In 2017 the SSSV failed and a K-valve was installed. The additional tubing pressure required by the K-valve does not allow the well to produce to its full potential. This proposed work will keep the original D-2 lateral. In addition it will add the B-1, B-3, and B-5 sands. Safety Concerns: x Discuss nitrogen asphyxiation concerns and identify any areas where nitrogen could collect and people could enter. x Consider tank placement based on wind direction and current weather forecast (venting methane and Nitrogen during this job) x Ensure all crews are aware of stop job authority (Review Standard Well Procedure – Nitrogen Operations) Wireline work: x Slickline will remove K-valve x Fish out or push down SL tools at ±4,730’ x A retrievable plug will be set at ±4,760’ o Test tubing against plug to ±900 psig with gas. x Dummy GLM at ±4,726’ if not recovering mandrel during workover x Pull GLV at ±3,456’ for circulation x Tubing cut at either a minimum depth of ±4,380’ or just below bottom GLM at ±4,750’ Procedure: 1.

MIRU Nitrogen Pumping Unit and Liquid Nitrogen Transport. 2.) Notify Facility Operator of upcoming Nitrogen operations. 3.) Perform Pre-Job Safety Meeting. Review operating procedures and appropriate Safety Data Sheets (formerly MSDS). 4.) Document hazards and mitigation measures and confirm flow paths. Include review on asphyxiation caused by nitrogen displacing oxygen. Mitigation measures include appropriate routing of flowlines, adequate venting and atmospheric monitoring. 5.) Spot Pumping Unit and Nitrogen Tank. Confirm liquid N2 volumes in transport. 6.) Rig up lines from the Nitrogen Pumping Unit to the well and returns tank. Secure lines with whip checks. 7.) Place signs and placards warning of high pressure and nitrogen operations at areas where Nitrogen may accumulate or be released. 8.) Place pressure gauges downstream of liquid and nitrogen pumps to adequately measure tubing and casing pressures. 9.) Place pressure gauges upstream and downstream of any check valves. 10.) Wellsite Manager shall walk down valve alignments and ensure valve position is correct. 11.) Ensure portable 4-gas detection equipment is onsite, calibrated, and bump tested properly to detect LEL/H2S/CO2/O2 levels. Ensure supplier has a working and calibrated detector as well that measures O2 levels. 12.) Pressure test lines upstream of well to approved sundry pressure or MPSP (Maximum Potential Surface Pressure), whichever is higher. Test lines downstream of well (from well to returns tank) to 1,500 psi. Perform visual inspection for any leaks. 13.) Bleed off test pressure and prepare for pumping nitrogen. 14.) Pump nitrogen at desired rate, monitoring rate (SCFM) and pressure (PSI). All nitrogen returns are to be routed to the returns tank. 15.) When final nitrogen volume has been achieved, isolate well from Nitrogen Pumping Unit and bleed down lines between well and Nitrogen Pumping Unit. 16.) Once you have confirmed lines are bled down, no trapped pressure exists, and no nitrogen has accumulated begin rig down of lines from the Nitrogen Pumping Unit. 17.) Finalize job log and discuss operations with Wellsite Manager. Document any lessons learned and confirm final rates/pressure/volumes of the job and remaining nitrogen in the transport. 18.)

Rig 404 BOP Test Procedure Attachment #1 Attachment #1 Hilcorp Alaska, LLC - BOP Test Procedure: Rig 404, WO Program – Oil Producers, Gas Producers, Water Injectors Pre Rig Move 1) Blow down well, bleed gas to Well Clean Tank that is vented thru flare to atmosphere 2) Load well with FIW to kill well. x Note: Fluid level will fall to a depth that balances with reservoir pressure. 3) Shoot fluid level at least 24 hours before moving on well. 4) Shoot fluid level again, right before ND/NU. Confirm that well is static. Initial Test (i.e. Tubing Hanger is in the Wellhead) If BPV profile is good 1) Set BPV. ND Tree. NU BOP. 2) MU landing joint. Pull BPV. Set 2-way check in hanger. 3) Space out test joint so end of tubing (EOT) is just above the blind rams. 4) Set slips, mark same. Test BOPE per standard test procedure. If the tubing hanger won’t pressure test due to either a penetrator leak or the BPV profile is eroded and/or corroded and BPV cannot be set with tree on. Profile and/or landing threads must be prepped while tree is off. Worst Case: BPV profile and landing threads are bad. 1) Attempt to set BPV through tree. If unsuccessful, shoot fluid level. 2) If fluid level is static from previous fluid level shots, notify Hilcorp Anchorage office that the well is static and the tree must be removed with no BPV. As approved in the sundry, proceed as follows: a) ND tree with no BPV b) Inspect and prepare BPV profile to accept a 2-way valve, or prepare lift-threads to accept landing joint to hold pressure. If well is a producer and the culprit is scale, attempt to clean profile with Muriatic acid and a wire brush or wheel. c) Set 2-way check valve by hand, or MU landing (test) joint to lift-threads d) For ESP wells - Ensure that cap is on cable penetrator e) NU BOP. Test BOPE per standard procedure. 3) If both set of threads appear to be bad and unable to hold a pressure test and / or a penetrator leaks, notify Operations Engineer (Hilcorp), Mr. Guy Schwartz (AOGCC) and Mr. Jim Regg (AOGCC) via email explaining the wellhead situation prior to performing the rolling test. AOGCC may elect to send an inspector to witness. As outlined and approved in the sundry, proceed as follows: a) Nipple Up BOPE b) With stack out of the test path, test choke manifold per standard procedure c) Conduct a rolling test: Test the rams and annular with the pump continuing to pump, (monitor the surface equipment for leaks to ensure that the fluid is going down-hole and not leaking anywhere at surface.) d) Hold a constant pressure on the equipment and monitor the fluid/pump rate into the well. Record the pumping rate and pressure. e) Once the BOP ram and annular tests are completed, test the remainder of the system following the normal test procedure (floor valves, gas detection, etc.) Rig 404 BOP Test Procedure Attachment #1 f) Record and report this test with notes in the remarks column that the tubing hanger/BPV profile / penetrator wouldn’t hold pressure and rolling test was performed on BOP Equipment and list items, pressures and rates. 4) Pull hanger to surface. (Requires tubing cuts as necessary to free tubing). CBU to displace annulus and tubing with kill weight fluid. 5) If a rolling test was conducted, remove the old hanger, MU new hanger or test plug to the completion tubing. Re-land hanger (or test plug) in tubing head. Test BOPE per standard procedure. Subsequent Tests (i.e. Test Plug can be set in the Tubing-head) 1) Remove wear bushing. a) Use inverted test plug to pull wear busing. MU to joint of tubing. b) Thread into wear bushing c) Back out hold down pins d) Pull and retrieve wear bushing. 2) Break off test plug and invert same- RIH with test plug on joint of tubing. Install a pump-in sub w/ test line plus an open TIW or lower Kelly valve in top of test joint w/ open IBOP. 3) Test BOPE per standard procedure. STANDARD BOPE TEST PROCEDURE (after 2-way check or test plug is set) 1) Fill stack and all lines with rig pump- install chart recorder on test line connected to pump-in sub below safety valve and IBOP in test joint assembly. 2) Note: When testing, pressure up with pump to desired pressure, close valve on pump manifold to trap pressure and read same with chart recorder (test pressures will be indicated in Sundry). 3) Referencing the attached schematics test rams and valves as follows. a) Close 1 st valve on standpipe manifold, close valves 1, 2, 10 on choke manifold and close the annular preventer, open safety valve on top of test jt and close IBOP. Pressure test to 250 psi for 5 minutes and xxx psi (see sundry) high for 5 minutes. If passes after 5 minutes on each, bleed off pressure back to tank and open annular. b) Close pipe rams and open annular preventer, close safety valve and open IBOP on test joint, close outside valve on kill side of mud cross, open 1st valve of standpipe, close valves 3, 4 & 9 on choke manifold, open valves 1 & 2 on choke manifold. Test to 250 psi for 5 minutes and xxx psi (see sundry) high for 5 minutes. If passes after 5 minutes on each, bleed off pressure back to tank. c) Test Dual Rams. If the well has dual tubing, and dual rams are installed in the stack, test the dual rams by picking up two test joints with dual elevators and lowering them into stack and position them properly in the dual rams. Close rams. Test to 250 psi for 5 minutes and xxx psi (see sundry) for 5 minutes. If passes after 5 minutes on each, bleed off pressure back to tank. d) Close inside valve / open outside valve on kill side of mud cross, close valves 5 & 6 / open valves 3 & 4 on choke manifold. Test to 250 psi for 5 minutes and xxx psi (see sundry) for 5 minutes. If passes after 5 minutes on each, bleed off pressure back to tank. e) Close manual and super choke / open valves 5 & 6 on choke manifold. Pressure up to ~ 1200 psi and bleed off 200 – 300 #s recording change and stabilization. If passes after 5 minutes, bleed off pressure back to tank. f) Close HCR (outside valve on choke side of mud cross), open manual & super choke. Test to 250 psi for 5 minutes and xxx psi (see sundry) for 5 minutes. If passes after 5 minutes on each, bleed off pressure back to tank. Rig 404 BOP Test Procedure Attachment #1 g) Close inside valve / open outside valve (HCR) on choke side of mud cross. Test to 250 psi for 5 minutes and xxx psi (see sundry) for 5 minutes. If passes after 5 minutes on each, bleed off pressure back to tank. h) Ensure all pressure is bled off- open pipe rams and pull test joint leaving test plug / 2-way check in place. Close blind rams and attach test line to valve 10 on choke manifold, close valve 7 & 8 / open valve 10 on choke manifold. Test to 250 psi for 5 minutes and xxx psi (see sundry) for 5 minutes. If passes after 5 minutes on each, bleed off pressure back to tank. i) Test additional floor valves (TIW or Lower Kelly Valve) and IBOPs as necessary. STANDARD TEST PROCEDURE OF CLOSING UNIT (ACCUMULATOR) 1) This is a test of stored energy. Shut off all power to electric and pneumatic pumps. 2) Record “Accumulator Pressure”. It should be +/- 3,000 psi. 3) Close Annular Preventer, the Pipe Rams, and HCR. Close 2 nd set of pipe rams if installed (e.g. dual pipe rams). Open the lower pipe rams to simulate the closing volume on the blinds. 4) Allow pressures to stabilize. 5) While stabilizing: Record pressure values of each Nitrogen bottle and average over the number of bottles. (i.e. Report might read “10 bottles at 2,150 psi”). 6) After accumulator has stabilized, record accumulator pressure again. This represents the pressure and volume remaining after all preventers are closed. (The stabilized pressure must be at least 200 psi above the pre- charge pressure of 1,000 psi). 7) Turn on the pump and record the amount of time it takes to build an additional 200 psi on the accumulator gauge. This is usually +/- 30 seconds. 8) Once 200 psi pressure build is reached, turn on the pneumatic pumps and record the time it takes for the pumps to automatically shut-off after the pressure to builds back to original pressure (+/- 3,000 psi). Note: Make sure the electric pump is turned to “Auto”, not “Manual” so the pumps will kick-off automatically. 9) Open all rams and annular and close HCR to place BOPE back into operating position for well work. 10) Fill out AOGCC report. FINAL STEP, FINAL CHECK 1) Test Gas Alarms 2) Double check all rams and valves, for correct operating position 3) Fill out the AOGCC BOPE Test Form (10-424) in Excel Format and e-mail to AOGCC and Juanita Lovett. Document both the rolling test and the follow up tests.

Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. When providing notice for a representative of the Commission to witness any required test, contact the Commission's petroleum field inspector at (907) 659 -3607 (pager).

Box 196427 Anchorage, AK 99519 -6247 Re: The request of Union Oil Company of California, operator of the Trading Bay Unit (TBU), for an Administrative Approval granting an exception to the well spacing requirements of Conservation Order 228 to drill and produce the TBU M -10 Middle Kenai Gas Pool well. Dear Mr. Martin: The Alaska Oil and Gas Conservation Commission (Commission) hereby approves Union Oil Company of California (UNOCAL)'s request for an exception to the well spacing requirements of Conservation Order 228 (CO 228) to drill and produce the TBU M -10 Middle Kenai Gas Pool well. The Commission received UNOCAL's request for Administrative Approval Pursuant to Rule 3 CO 228 for exception to the well spacing requirements of CO 228 on January 21, 2010. TBU M -10 will be a horizontal gas production well with a surface location 1,052 feet from the north line and 464 feet from the west line of Section 33, T9N, R13W, Seward Meridian (S.M.) and a projected bottom hole location of 156 feet from the south line and 1,563 feet from the west line of Section 28, T9N, R 13W, S.M. TBU M -10 will target the D -2 reservoir sand in the Tyonek Formation. The proposed TBU M -10 well and existing gas production well TBU M -03 will both be open to the D -2 reservoir sand within a 10 -acre block, in violation of the well spacing requirement established by Rule 1 of CO 228. An exception to Rule 1 is necessary to allow drilling and regular production of the TBU M -10 well from the D -2 reservoir sand. The productive interval of TBU M -10 open to the D -2 reservoir sand will be located entirely within Segment C of State of Alaska lease ADL 18730, established with the Alaska Department of Natural Resources on September 4, 2003. Segment C of State lease ADL 18730 is jointly owned by UNOCAL (48.8 %) and Marathon Alaska Production Company (51.2 %), and it lies within the boundaries of the TBU and the Grayling Gas Sands Participating Area (PA). UNOCAL is the operator for the TBU and the Grayling Gas Sands PA. • • CO 228.07 January 28, 2010 Page 2 of 2 Because of sand and water production problems, existing well TBU M -03 is not efficiently draining the gas reserves with the D -2 reservoir sand. The horizontal TBU M- 10 production well will more efficiently recover these reserves. A spacing exception to allow drilling and regular production from the TBU M -10 well will not result in waste or jeopardize the correlative rights of adjoining or nearby owners. Rule 3 of CO 228 allows the Commission to administratively amend the order as long as the operator demonstrates to the Commission's satisfaction that sound engineering practices are maintained and the amendment will not result in physical waste. The Alaska Oil and Gas Conservation Commission hereby authorizes the drilling and regular production of the TBU M -10 well pursuant to Rule 3 of CO 228.

Commission Alaska Oil & Gas Conservation Commission Anchorage 333 W. 7 Avenue Anchorage, Alaska 99501 Re: Steelhead Platform, Trading Bay Unit M -10, APD 2091540 Dear Commissioner, Enclosed for review and approval is the re- application for the Permit to Drill the Trading Bay Unit M -10 well from the Steelhead Platform. The above referenced well was spud 1/7/10. A pilot hole was drilled through the primary objective horizon (D3B) and on to a TD of 6940 MD. Log analysis indicates that the D3 is non - productive. As was the alternative plan, Union Oil Company of California intends to drill a horizontal wellbore into the secondary objective (D2). The proposed bottom hole location io in the D2 is not more than 500' vertically or laterally from the original permitted location in the D3. Pursuant to 20 AAC 25.05 and Conservation Ord 28, a spacing exception is needed to produce this wellbore in the planned D2 location. The TBU wellbore is open to production (though not likely producing) from the D2 and is separated from ,th planned trajectory of M -10 by 357' at 6884' MD of / the planned M -10 D2 trajectory. Union Oil Company of California therefore requests administrative approval of the spacing exception pursuant to Rule 3 of Conservation Order 228. The rig is currently plugging and abandoning the pilot hole and plans to start sidetrack operations within 36 hrs. ' Your timely review and approval of this APD and spacing exception request will be appreciated. In accordance with 20 AAC 25.005 (c)(4)(A -C)... (A) MASP calculations are attached for review. (B) The Grayling Gas Sands are potentially gas bearing throughout the section. The D2 is expected to have a pore pressure of approximately -450 psi. (C) Due to ongoing production operations in this field, sub - normally pressured sands occur in multiple places. Lost circulation and differential sticking are potential problems. Conventional solutions such as LCM and good drilling practice are intended to ameliorate the problems. An exception to 20 AAC 25.035 (c)(1)(B) is requested. The diverter system at Steelhead includes two 16" diameter diverter lines. The surface hole 4 section of M -10 is planned to be drilled with a 17'/" bit. Union Oil Company of California / A Chevron Company Page 1. of 2 • An exception to 20 AAC 25.035 (e)(3) is requested. The BOP stack for Steelhead includes 20 %" 3M ram preventers and a 21 %a" 2M annular preventer. The MASP for the subject well, when calculated in the most pessimistic manner, exceeds the rated working pressure of the annular preventer. The annular preventer will not be used in a secondary well control event in excess of its rated working pressure. Union Oil Company also requests that the test pressure for the annular be established at 1000 psi. The annular preventer has been previously tested to 2000 psi. Repeated testing to 2000 psi will degrade the annular element. Pursuant to 20 AAC 25.005 (c)(14)... Qualified drilling waste will be discharged in accordance with NPDES permit AKG -31 -5000 which became effective 7/2/2007 and expires 7/2/2012. At this time, Union Oil Company does not intend to apply for annular disposal approval. 7 The remaining requirements of 20 AAC 25.005 are attached for review or currently on file with the Commission.

The well will be spudded with a pre- hydrated gel drilling fluid and the 17 -'/" interval will then be drilled to section TD at 1,401' MD where 13 -3/8" casing will be run and cemented. The 9 -1/4" pilot hole will be drilled to 6,900'. Cement plugs will be utilized to plug back the pilot hole to approximately 4500' MD, where an open hole sidetrack will kick off to drill the 9 "'A" interval to the 7" casing point at 5759' MD. The 7" casing will be run and cemented. The 6 -1/8" production horizontal will be drilled to TD at 7,126' MD. A 4 -' /" wire - wrapped screen, open hole completion will be ran. 6% KCI brine and corrosion inhibitor will be required for completion. Spud the well with a FW AQUAGEL mud at 9.0 ppg. The mud weight will then be held in the 9.0 to 9.3 ppg mud weight range to the surface hole TD unless hole conditions dictate otherwise. Our primary focus for surface hole drilling operations will be adequate mud weight for well control and sufficient mud viscosity for efficient hole cleaning. Before cementing the surface casing, ensure the mud weight is 9.5 ppg. LCM will be added to help strengthen the wellbore. A 2% KCI /CLAYSEAL /GEM mud will be maintained through the 9 -1/4" interval. This mud offers good LCM responses if losses are encountered. Special emphasis should be placed on maintaining low ECD's and surge /swab pressures to minimize the potential for lost circulation and disturbing the coal beds. This mud is formulated with three mechanisms to provide waste minimization and effective wellbore stabilization: glycol (GEM GP), ionic inhibition (KCI), and polymer encapsulation (Clayseal). Barotrol can be used to help stabilize the coal seams. The filtrate will be tightened in the lower section of the interval. Background LCM will be added to help seal and strengthen the wellbore. The production interval will utilize an 8.8 ppg 2% KCI BARADRILn system built from freshwater. Baracarbs 5/25/50 will be strung into the system while drilling to help prevent differential sticking and reduce formation damage. The mud weight will be maintained to TD. Primary Drilling Objectives: • Not exceeding the maximum allowable concentration of any product • Monitoring all discharges • Zero fluid related HSE incidents • Achieve wellbore stability • Achieve good hole cleaning considering hole angle, geometry and anticipated ROP rates • Lost circulation mitigation/control • Achieve good Zonal Isolation as per plan • Achieve minimal formation damage im a to r • . s Neams United States of America Cook Inlet Baroid Fluid Services Kenai Offshore, Alaska 1 -19 -10 -- Page 3 of 25 BAROID FLUID SERVICES S Operator • CHEVRON - MID - CONTINENT P EBIZ v 1.3 Well Name M -10 Critical Fluid Issues: • Eliminating /controlling losses in the under pressured zones. • Maintaining a low ECD in the production zone to reduce risk of lost returns. • Maintaining a stable wellbore through coal seams by reducing ECD's, surge, and swab. • Reducing drilling wastes with the inhibited drilling fluid system. • Follow new NPDES regulations Well Specifics: Casing Program MD Footage 17 -1/2" hole (13 -3/8" csg) 1401 931 9 -1/4" hole (7" csg to 5759') 5759 4358 6 -1/8" Hole (4 -1/2" Screens) 7126 1367 HALLI B U RTO N United States of America Cook Inlet Baroid Fluid Services Kenai Offshore, Alaska 1 -19 -10 -- Page 4 of 25 BAROID FLUID SERVICES.

Filtrate control: Maintain the filtrate <8 using DEXTRID and /or PAC L. Additions of CONDET may be required to control screen blinding /BHA balling. Losses in this interval can be controlled with additions of 3 ppb BAROFIBRE and 3 ppb of Baracarb 50 or by dedicated LCM pills. Operations Summary: Mix a -50 bbl LCM pill prior to drilling out. The pill formulation will be: 45 bbls base mud, 15 ppb BAROFIBRE, and 15 ppb of BARACARB 50. Pre - hydrated AQUAGEL should be used to maintain rheological parameters. Maintain the mud as clean as possible while drilling. Should sweeps be required, a high viscosity sweep is recommended. Run DFG (Drilling Fluid Graphics) to confirm hole cleaning efficiency based on current rheology, flow rates, angle and cuttings size. Sweep Formulation: 65 bbl of mud with -1 pp b of BARAZAN D+ added. AQUAGEL and BARAZAN D+ should be used to maintain rehology. X -TEND II should be used to supplement the AQUAGEL. DEXTRID and /or PAC L should be used for filtrate control. Background LCM (10 ppb total) BARACARBs /BAROFIBRE /STEELSEALs should be maintained in the system while drilling the surface interval to prevent losses and strengthen the wellbore. While drilling, monitor the torque and drag to determine if liquid lubricant is required. If so, approval from town will be required prior to additions of lubricants.

O e ra CHEVRON - MID - CONTINENT • P EBIZ v 1.3 Well Name M -10 At TD, a Wallnut "flag" (30 bbl pill with 5 ppb of WALLNUT M) or carbide pill should be pumped to gauge hole washout and to calculate the required cement volume. The cement will then be pumped and drilling mud will be used to bump the plug. Pretreat this chase mud with 1 ppb Bicarb and 0.5 ppb citric acid. The mud weight will be increased to 9.5 ppg before running surface casing and cementing. Losses have historically occurred in this interval. Ensure that the mud weight is maintained in the 9.0 -9.3 ppg range through this area. Maintaining background LCM concentrations at 10 ppb total ( BARACARBs /BAROFIBRE /STEELSEALs) has proven successful on M -17, M -18, M -06, and M -20. Stress slow pipe movement to the drillers to reduce surge /swab on the zone. Stage pumps on slowly after connections and begin rotation prior to pumping (this will break the gels and reduce the pressure required to break the gels). Reduce system YP with BARATHIN or CARBONOX as required for running casing (do not jeopardize hole conditions). Run casing carefully to minimize surge and swab pressures. Reduce the system rheology with BARATHIN or CARBONOX once the casing is landed to a YP < 20 (check with the cementers to see what yp value they have targeted). Consider spotting a STEELSEAL 400 LCM pill prior to running the 13 -3/8" casing if losses have been seen in this interval. The plug will be bumped with mud on the well. This well is a large borehole. Modeling shows that it will become much more difficult to clean if flowrates drop below 800 gpm. Maintain a minimum 25 YP at all times. Be prepared to increase the YP if hole cleaning becomes an issue. Run DFG (Drilling Fluid Graphics) to confirm hole cleaning efficiency based on current rheology, flow rates and cuttings size. Maximum Acceptable ROP in fph at Specified GPM and RPM GPM—) 600 800 1000 80 rpm 48 64 87 100 rpm 52 74 95 Baroid recommends a flowrate in the 800 gpm range to maximize hole cleaning efficiencies at these higher penetration rates. However if losses occur, the flow rate can be reduced in conjunction with a slower penetration rate which would reduce the ECD /losses.

As the mud shears, slowly raise the CLAYSEAL concentration to its full 4 ppb concentration. GEM GP should be maintained at 1.5% v/v (5.2 ppb). BARAZAN- D+ should be used to maintain rheological parameters. Maintain the mud as clean as possible while drilling. Should sweeps be required, a high viscosity sweep is recommended. Sweep Formulation: 50 bbl of mud with -1 ppb of BARAZAN D+ added. DEXTRID and PAC L should be used for filtrate control (6cc range). 4 ppb BAROTROL should be added to help control coals and shales. While drilling, monitor the torque and drag to determine if liquid lubricant is required. If so, approval from town will be required prior to additions of lubricants. STICKLESS 20 drilling beads could provide an alternative to lubricants. Additions of CONDET are recommended to reduce the incidence of bit balling and shaker blinding when penetrating high -clay content sections. Maintain the pH in the 8.5 - 9.5 range with caustic soda. Daily additions of ALDACIDE G / X -Cide 207 should be made to control bacterial action. Maintain Cl- with 2% KCI. The GEM GP can be raised above the 1.5% level to help reduce torque. Do not exceed 3% v/v of GEM GP. At TD, the pilot hole will be plugged back to -4500' MD and then an open hole sidetrack will be performed and drilled to the 7" casing depth at 5759' MD. The 7" casing will be run and cemented. Reduce system YP as required for running casing (do not jeopardize hole conditions). Run casing carefully to minimize surge and swab pressures. Reduce the system rheology once the casing is landed to a YP < 15 (check with the cementers to see what YP value they have targeted). Consider spotting a STEELSEAL LCM pill (20 ppb of the different sizes of STEELSEAL) prior to running the casing if losses have been seen in this interval.

Pump 50 bbl STEELSEAL pill: 45 bbl mud with 50 sx (50 ppb) STEELSEAL added 2. Chase with 50 bbl HYDRO -PLUG pill: 50 bbl water, 80 sx (80 ppb) HYDRO -PLUG 3. Make sure the HYDRO -PLUG pill clears the pipe. Apply a squeeze of 150 -250 psi. (see attached) 4. If possible, drill through the loss zone prior to spotting the pills, otherwise there's a good chance you'll lose circulation again. HYDROPLUG Mixing and Spotting Procedures Overview HYDRO -PLUG is self - expanding lost circulation material (LCM) that hydrates with time and temperature. HYDRO - PLUG is pumped in an un- hydrated state in a liquid medium. The liquid pill is designed to pass through measurement - while- drilling (MWD) and other downhole tools. The HYDRO -PLUG lost circulation treatment is compatible with both invert emulsion and waterbase fluids. Rig pumps are normally used to place HYDRO -PLUG. No special equipment is required. For best results, FRESH COLD water only should be used to mix in. Mixing Procedures Caution: Do not add Lime or Caustic Soda. Make sure the pill pit is clean. Do not add any chemicals other than the viscosifiers recommended below. • Un- weighted - No viscosifying agent is required. - Mix 80 lbs per bbl of HYDRO -PLUG in fresh water. - Pump immediately. • Weighted up to 12.0 ppg - Mix 0.50 to 0.75 lbs per bbl BARAZAN in fresh water. - Add barite for desired density - Then add 80 lbs per bbl HYDRO -PLUG through the hopper. Run a small stream of fresh water while mixing the Hydro - Plug, as barite will absorb some free water. - Pump immediately. • Weighted from 12.0 to 17.0 ppg - Mix 6 lbs per bbl AQUAGEL in fresh water. - Add barite for desired density. - Then add 60 lbs per bbl HYDRO -PLUG through the hopper. Run a small stream of fresh water while mixing the Hydro - Plug, as barite will absorb some free water. - Pump immediately. Pill Volumes • 8 Hole: 40 to 50 bbl minimum. • 6" Hole: 25 to 30 bbl minimum.

Note: Plan and prepare ahead of time. The mixing, pumping and spotting of the pill should take no more than 90 to 120 minutes. Setting Times Ensure to obtain the correct BHT prior to pumping. Temp Time 70 — 100° F 5 — 7 hours 100 —150° F 4 — 6 hours 150 — 200° F 3 — 4 hours 200 — 300° F 2 — 3 hours Another Application — Cement Plug/Cement Squeeze HYDRO -PLUG can be used to help achieve a successful cement job. Procedure: Mix HYDRO -PLUG material as per above mixing instructions, then pump and clear pipe prior to pumping cement. As the cement is pumped, HYDRO -PLUG will penetrate and seal fractures, thus allowing cement returns to surface.

All operations shall proceed with the necessary precautions to prevent a kick. Special attention is required in the following areas: 1. Monitor trip tank on each trip into and out of the hole. 2. Carefully monitor PVT for gain / loss. 3. Have LCM material onboard and ready for use in the event significant losses occur. 4. Minimize surge and swab pressures while tripping. 5. Review cement spacers and washes to ensure the well is not under balanced at any point during cementing operations. 6. Perform diverter drills until the crews are familiar with the procedure. • M -10 wellbore passes all major risk to surrounding wellbores. Record annulus pressures on surrounding well (M -19, M -14, M -15 and M -13) prior to spud and monitor during the drilling of the surface hole section. 9 1 /4" Hole Sections • Shallow gas sands will be encountered that have the potential to flow and cause a loss of well control.

Carefully monitor PVT for gain / loss. 3. Have LCM material onboard and ready for use in the event significant losses occur. 4. Minimize surge and swab pressures while tripping. 5. Review cement spacers and washes to ensure the well is not under balanced at any point during cementing operations. 6 1/8" Hole Section • Significantly under pressured reservoir sands will be encountered A heightened awareness of kick detection, pre -job planning and trip tank calibration will be essential while drilling /trip ping the intermediate interval. • Loss circulation is considered to be a major risk due to the depleted reservoir sands which will be encountered. Loss circulation materials will be readily available for adding to the mud system should significant losses be encountered. Consult the Lost Circulation Decision Tree regarding LCM treatments and procedures • Differential sticking is a considerable risk while drilling these depleted sands. Keep the drill string moving whenever possible. • Numerous coals will be drilled through. Unocal coal drilling strategy; limiting the amount of coal drilled ( <10') prior to back reaming should be followed. HYDROGEN SULFIDE - H2S • Steelhead is designated as an H2S drill site. Standard Operating Procedures for H2S precautions should be followed at all times.

Pressure at which this first occurs is the leak-off point. • LOT Limit - 16.0 ppg EMW for all surface casing shoe tests; determined from previous experience with formation breakdown problems by attempting higher leak-offs. • Open Hole LOTs (OH LOTs)- Leak-off tests performed with open hole from the casing shoe to some point above the target reservoir. Generally done when leak-off is required but could not be achieved just below the casing shoe; or where weaker formations are suspected above the target reservoir but below the casing shoe, and assurance is required of being able to achieve estimated mud weight. Procedure for FIT: 1. Drill 20' of new hole below the casing shoe. 2. Circulate the hole to establish a uniform mud density throughout the system. P/U into the shoe. 3. Close the blowout preventer (ram or annular). 4. Pump down the drill stem at 1/4 to 1/2 bpm. 5. On a graph with the recent casing test already shown, plot the fluid pumped (volume or strokes) vs. drillpipe pressure until appropriate surface pressure is achieved for FIT at shoe. 6. Shut down at required surface pressure. Hold for a minimum 10 minutes or until the pressure stabilizes, Record time vs. pressure in 1-minute intervals. 7. Bleed the pressure off and record the fluid volume recovered. The pre-determined surface pressure for each formation integrity test is based on achieving an EMW at least 1.0 ppg higher than the estimated reservoir pressure, and allowing for an appropriate amount of kick tolerance in case well control measures are required. Formation integrity tests are conducted on all casing shoes with the exception of some surface casing situations. Where annular pumping will be done on a well, the formation below the surface shoe is taken to leak-off. This ensures that future disposal fluids can pumped away without risk of damage to the surface shoe. If two attempts at establishing leak-off at the shoe are unsuccessful (using 16.0 ppg EMW LOT limit per definition above), then an open-hole LOT is performed. Where required, the LOT is performed in the same fashion as the formation integrity test, Instead of stopping at a pre-determined point, surface pressure is increased until the formation begins to take fluid; at this point the pressure will continue to rise, but at a slower rate. The system is shut in and pressure monitored as with an FIT. • • -Now ° 'wit ik G i i ._ i I -I /G' ,0psI i I H 2 A I .P i STACK LEVEL II 1 u u INSPECTION ®LIFTING DEVICE ii r 0111.i.

Commission Re: Steelhead Platform, Trading Bay Unit M -10 / Anchorage Dear Commissioner, Enclosed for review and approval is the application for the Permit to Drill the Trading Bay Unit M -10 well from the Steelhead Platform. Drilling operations are expected to commence approximately November 3, . ;009 depending on the progress of other ongoing projects. Per Conservation Order 228, Trading Bay Unit requires 10 acre . - •ng. There are no wells producing or capa f production from the target strata of TBU / 1 within 745' of the planned wellpath of TBU M 0 Therefore, a spacing exemption is not requir - • 0 drill or produce TBU M -10. The 9 %" intermediate hole will have a pilot hole drilled below the target sand to evaluate future productive horizons. The MASP has been calculated to the deepest expected TVD of the pilot hole. Based on the well design of the planned horizontal section being landed shallower than the pilot hole, no FITwill be performed after drilling out of the 7" casing. In accordance with 20 AAC 25.005 (c)(4)(A -C)... (A) MASP calculations are attached for review. (B) The Grayling Gas Sands are potentially gas bearing throughout the section. Potential target reservoirs and their predicted pore pressures are indicated in the attached M -10 Well Design Summary. (C) Due to ongoing production operations in this field, sub - normally pressured sands occur in multiple places. Lost circulation and differential sticking are potential problems. Conventional solutions such as LCM and good drilling practice are intended to , ameliorate the problems. I An exception to 20 AAC 25.035 (c)(1)(B) is requested. a35 L \ The diverter system at Steelhead includes two 16" diameter diverter lines. The surface hole section of M -10 is planned to be drilled with a 17 %" bit. / Union Oil Company of California / A Chevron Company Page 1 of 2 • • An exception to 20 AAC 25.035 (e)(3) is requested. ✓ ( L i o The BOP stack for Steelhead includes 20 3 /" 3M ram preventers and a 21 %4" 2M annular preventer. The MASP for the subject well, when calculated in the most pessimistic manner, exceeds the rated working pressure of the annular preventer. The annular preventer will not be used in a secondary well control event in excess of its rated working pressure. Union Oil Company also requests that the test pressure for the annular be established at 1000 - psi. The annular preventer has been previously tested to 2000 psi. Repeated testing to 2000 psi will degrade the annular element. Pursuant to 20 AAC 25.005 (c)(14)... Qualified drilling waste will be discharged in accordance with NPDES permit AKG -31 -5000 j which became effective 7/2/2007 and expires 7/2/2012. At this time, Union Oil Company does notjntend to apply for annular disposal approval. The remaining requirements of 20 AAC 25.005 are attached for review or currently on file with the Commission.

Version 1.0 Rigsite Hazards and Contingencies BAROID FLUID SERVICES • O era CHEVRON - MID - CONTINENT P EBIZ v 1.1 Well Name M -10 Objective and Methods Steelhead Producer Introduction: The following mud program was prepared for a deviated well on the Steelhead platform in the Cook Inlet, Alaska. The well will be spudded with a pre- hydrated gel drilling fluid and the 17-%" interval will then be drilled to section TD at 1,401' MD where 13 -3/8" casing will be run and cemented. The 9 -1/4" pilot hole will be drilled to 6,900'. A balanced heavy weight mud will be spotted in the open hole from 6,100' to 6,900'. The 7" casing will be ran and cemented at 6,100'. The 7" casing will be drilled out and some /all of the heavy mud will circulated out of the hole. The 9 -1/4" Pilot hole will be abandoned with cement plugs at the horizontal kickoff depth. The 6 -1/8" production horizontal will be drilled to TD at 7,620' MD. A 4 -'h" wire - wrapped screen, open hole completion will be ran. 6% KCI brine and corrosion inhibitor will be required for completion. Spud the well with a FW AQUAGEL mud at 9.0 ppg. The mud weight will then be held in the 9.0 to 9.3 ppg mud weight range to the surface hole TD unless hole conditions dictate otherwise. Our primary focus for surface hole drilling operations will be adequate mud weight for well control and sufficient mud viscosity for efficient hole cleaning. Before cementing the surface casing, ensure the mud weight is 9.5 ppg. LCM will be added to help strengthen the wellbore. A 2% KCI /CLAYSEAL /GEM mud will be maintained through the 9 -1/4" interval. This mud offers good LCM responses if losses are encountered. Special emphasis should be placed on maintaining low ECD's and surge /swab pressures to minimize the potential for lost circulation and disturbing the coal beds. This mud is formulated with three mechanisms to provide waste minimization and effective wellbore stabilization: glycol (GEM GP), ionic inhibition (KCI), and polymer encapsulation (Clayseal). Barotrol can be used to help stabilize the coal seams. The filtrate will be tightened in the lower section of the interval. Background LCM will be added to help seal and strengthen the wellbore. The production interval will utilize an 8.8 ppg 2% KCI BARADRILn system. Baracarbs 5/25/50 will be strung into the system while drilling to help prevent differential sticking and reduce formation damage. The mud weight will be maintained to TD. Primary Drilling Objectives: • Not exceeding the maximum allowable concentration of any product • Monitoring all discharges • Zero fluid related HSE incidents • Achieve wellbore stability • Achieve good hole cleaning considering hole angle, geometry and anticipated ROP rates • Lost circulation mitigation/control • Achieve good Zonal Isolation as per plan • Il4 Achieve iWii eev e minimal l�BU formation , ON United States of America Cook Inlet Baroid Fluid Services Kenai Offshore, Alaska 11 -23 -09 -- Page 3 of 25 BAROID FLUID SERVICES.

Losses in this interval can be controlled with additions of 3 ppb BAROFIBRE and 3 ppb of Baracarb 50 or by dedicated LCM pills. Operations Summary: Mix a -50 bbl LCM pill prior to drilling out. The pill formulation will be: 45 bbls base mud, 15 ppb BAROFIBRE, and 15 ppb of BARACARB 50. Pre - hydrated AQUAGEL should be used to maintain rheological parameters. Maintain the mud as clean as possible while drilling. Should sweeps be required, a high viscosity sweep is recommended. Run DFG (Drilling Fluid Graphics) to confirm hole cleaning efficiency based on current rheology, flow rates, angle and cuttings size. Sweep Formulation: 65 bbl of mud with -1 ppb of BARAZAN D+ added. AQUAGEL and BARAZAN D+ should be used to maintain rehology. X -TEND II should be used to supplement the AQUAGEL. DEXTRID and /or PAC L should be used for filtrate control. Background LCM (10 ppb total) BARACARBs /BAROFIBRE /STEELSEALs should be maintained in the system while drilling the surface interval to prevent losses and strengthen the wellbore.

The cement will then be pumped and drilling mud will be used to bump the plug. Pretreat this chase mud with 1 ppb Bicarb and 0.5 ppb citric acid. The mud weight will be increased to 9.5 ppg before running surface casing and cementing. Losses have historically occurred in this interval. Ensure that the mud weight is maintained in the 9.0 -9.3 ppg range through this area. Maintaining background LCM concentrations at 10 ppb total ( BARACARBs /BAROFIBRE /STEELSEALs) has proven successful on M -17, M -18, M -06, and M -20. Stress slow pipe movement to the drillers to reduce surge /swab on the zone. Stage pumps on slowly after connections and begin rotation prior to pumping (this will break the gels and reduce the pressure required to break the gels). Reduce system YP with BARATHIN or CARBONOX as required for running casing (do not jeopardize hole conditions). Run casing carefully to minimize surge and swab pressures. Reduce the system rheology with BARATHIN or CARBONOX once the casing is landed to a YP < 20 (check with the cementers to see what yp value they have targeted). Consider spotting a STEELSEAL 400 LCM pill prior to running the 13 -3/8" casing if losses have been seen in this interval. The plug will be bumped with mud on the well. This well is a large borehole. Modeling shows that it will become much more difficult to clean if flowrates drop below 800 gpm. Maintain a minimum 25 YP at all times. Be prepared to increase the YP if hole cleaning becomes an issue. Run DFG (Drilling Fluid Graphics) to confirm hole cleaning efficiency based on current rheology, flow rates and cuttings size. Maximum Acceptable ROP in fph at Specified GPM and RPM GPM--+ 600 800 1000 80 rpm 48 64 87 100 rpm 52 74 95 Baroid recommends a flowrate in the 800 gpm range to maximize hole cleaning efficiencies at these higher penetration rates. However if losses occur, the flow rate can be reduced in conjunction with a slower penetration rate which would reduce the ECD /losses. Hazards / Concerns — Surface Interval: • Optimize solids control equipment to maintain density and sand content. • Maintain YP between 25 -35 to optimize hole cleaning and to control ECD. • Pump high viscosity sweeps to enhance hole - cleaning efforts. Monitor sweep effectiveness. • Successfully land and cement casing.

Sweep Formulation: 50 bbl of mud with -1 ppb of BARAZAN D+ added. DEXTRID and PAC L should be used for filtrate control (6cc range). 4 ppb BAROTROL should be added to help control coals and shales. While drilling, monitor the torque and drag to determine if liquid lubricant is required. If so, approval from town will be required prior to additions of lubricants. STICKLESS 20 drilling beads could provide an alternative to lubricants. Additions of CONDET are recommended to reduce the incidence of bit balling and shaker blinding when penetrating high -clay content sections. Maintain the pH in the 8.5 - 9.5 range with caustic soda. Daily additions of ALDACIDE G / X -Cide 207 should be made to control bacterial action. Maintain Cl- with 2% KCI. The GEM GP can be raised above the 1.5% level to help reduce torque. Do not exceed 3% v/v of GEM GP. At TD, a 13.8 ppg balanced pill (base mud thinned and weighted to 13.8 ppg with barite) will be spotted from 6100' -6900' before the final trip out of the hole to run the 7" casing. The pill should be spotted with reduced pump rates to reduce the chance of losses. This pill will allow the 7" casing to be run and cemented at 6100' in a two stage cement job leaving 6100' - 6900' open - 1 stage cement will be 13.5 ppg. Reduce system YP as required for running casing (do not jeopardize hole conditions). Run casing carefully to minimize surge and swab pressures. Reduce the system rheology once the casing is landed to a YP < 15 (check with the cementers to see what YP value they have targeted). Consider spotting a STEELSEAL LCM pill (20 ppb of the different sizes of STEELSEAL) prior to running the casing if losses have been seen in this interval.

Based on offset drilling & well test data, the pore pressure gradient is predicted to be a 0.440 psi /ft gradient (8.7 EMW) from surface to planned total depth at 4785' ND BRT. 2.The 17' " surface hole will be drilled to approximately 1450'/1410' MD /TVD under an existing structural pile conductor and will use a diverter system for well control. The diverter system is not designed to shut the well in and contain pressure. Therefore, MASP is 0 psig for this hole section. 3. The M.A.S.P. during drilling operations will be governed by pore pressure at TD. The calculations take into account a gas gradient to surface of .1 psi /ft. The intermediate hole section will be drilled to a deeper TVD (Pilot Hole) to evaluate target sands. After evaluation a target sand will be chosen (D -3B or D -2) to drill a horizontal leg. The MASP is being calculated from the deepest expected ND of the pilot hole. 4. The M.A.S.P. during production operations will be the estimated SIBHP minus the gas hydrostatic pressure between TD & the surface. 17.5" Hole Fracture Pressure Conductor (470 ND): Max. Est.

Pressure at which this first occurs is the leak -off point. • LOT Limit - 16.0 ppg EMW for all surface casing shoe tests; determined from previous experience with formation breakdown problems by attempting higher leak -offs. • Open Hole LOTs (OH LOTs)- Leak -off tests performed with open hole from the casing shoe to some point above the target reservoir. Generally done when leak -off is required but could not be achieved just below the casing shoe; or where weaker formations are suspected above the target reservoir but below the casing shoe, and assurance is required of being able to achieve estimated mud weight. Procedure for FiT: 1. Drill 20 of new hole below the casing shoe. 2. Circulate the hole to establish a uniform mud density throughout the system. P/U into the shoe. 3. Close the blowout preventer (ram or annular). 4. Pump down the drill stem at 1/4 to 1/2 bpm. 5. On a graph with the recent casing test already shown, plot the fluid pumped (volume or strokes) vs. drillpipe pressure until appropriate surface pressure is achieved for FIT at shoe. 6. Shut down at required surface pressure. Hold for a minimum 10 minutes or until the pressure stabilizes. Record time vs. pressure in 1- minute intervals. 7. Bleed the pressure off and record the fluid volume recovered. The pre - determined surface pressur, for each formation integrity test is based on achieving an EMW at least 1.0 ppg higher than the estimated reservoir pressure, and allowing for an appropriate amount of kick tolerance in case well control measures are required. Formation integrity tests are conducted on all casing shoes with the exception of some - surface casing situations. Where annular pumping will be done on a well, the formation below the surface shoe is taken to leak -off. This ensures that future disposal fluids can pumped away without risk of damage to the surface shoe. If two attempts at establishing leak -off at the shoe are unsuccessful (using 16.0 ppg EMW LOT limit per definition above), then an open -hole LOT is performed. Where required, the LOT is performed in the same fashion as the formation integrity test. Instead of stopping at a pre - determined point, surface pressure is increased until the formation begins to take fluid; at this point the pressure will continue to rise, but at a slower rate. The system is shut in and pressure monitored as with an FIT. it -18 20 3/4" BOP / Diverter Stack up • i r 21 1/4" 2M Hydril Annular 4.22' I I HUB CLAMP I 20 3/4" 3 M Hydril DBL Gate Pipe Rams 4 .71' 20 3/4" 3M Bli R ams 1 1 I HUB CLAMP 20 3/4" 3M ucis Mud Cross 2.00' HUB CLAMP I I 20 3/4" 3M Single Gate 2.71' I HUB CLAMP 6" Ansi 600 Diverter Valves 20 3/4 3M 2.00 NT2 Connector XO Diverter Spool 3.00' 203/43MNT2 ------ a t,t41��1e, Connector I ,n, 1 20 3/4" 3M Riser 20 3/4" 3M Riser VETCO 20 3/4" NT2 Connector VETCO NT2 HEAD 6" ANSI 600 RTJ • 1 .

The BHA was a 17 W Hughes GTS -C1, bit sub, 17 stabilizer, 3 NMDC, XO, HWDP. This objective was accomplished. BHA 2 (480' 1442'MD / 480' 1411'TVD) Drilling Run The objective of the run was to build at 3 °I100 to the 13 3/8" casing point. This objective was accomplished. The BHA was a used 17 Hughes GTS -C1, 1.5° PDM, 16" stabilizer, Gyropulse, MWD, ARC, 17 stabilizer, 3 NMDC, XO, 18 HWDP. This assembly generated the required 3 °/100 with 50% sliding. After reaching 600' all slides were picked up above and reamed down with out any effect on our DLS. Once we were clear of any close approaches the survey interval was increased to 100'. The average ROP was 104 ft/hr. This was the 6 rerun for this bit. It was graded 2- 2- WT- S- IN- E- NO -TD. There is a fairly strong right hand walking tendency in the surface holes here. The trip out of the hole was without any problems. The 13 3/8" casing was cemented 40' off bottom due to not being able to wash it down any farther. It was cemented without problems. 9 1/4" Intermediate Hole BHA 4 (1442'- 1462'MD 1 1411'-1430'TVD) Drilling Run The objective of the run was to drill the float equipment and 20' of new hole for the FIT with a. This objective was accomplished. The BHA was a used 12 XR +C, bit sub, NMDC, 12 stabilizer, 2 NMDC, XO 18 HWDP. When we got the bit out of the hole it was discover that all three cones had been locked up while drilling the float equipment as there were flat spots on all three of them. There was not locking them up when we got out of the hole. We are thinking that while drilling the Davis Lynch cementer something got caught between the cones and locked them up as it took quite a bit to drill through it and the float equipment. Page 1 of 5 • BHA 5 (1462'- 5740'MD / 1430'- 4646'TVD) Drilling Run The objective of the run was to do the 4 °/100 curve to the casing point. This objective was not accomplished due to the bit wearing out. The BHA was a Smith MSi616 with 6 x 13's, Xceed 675, ARC, MWD, ADN675, 9 1/8" stabilizer, 1 NMDC, 6 HWDP, 6 1/2" jars, 11HWDP. The drilling parameters were 120 to 160 RPM, 5 to 12K WOB, and 650 to 750 GPM. The 4 °/100 was accomplished for the most part with a 60% setting on the Xceed. The DSL did not fall off until the bit dulled. The Xceed tool would generate DSL right at the programmed toolface. It did this even though it was only getting a good survey every or or 6th survey. So there was no issue with the angle X. Towards the end of the run it was down linked to get its angle X from the MWD as a precaution. A short trip was made at 4500'. It was made on elevators with a few minor tight spots. The trip out for the bit was also made on elevators. On surface the stabilizer above the ADN675 was worn down to 8 1 /8 ". The Xceed stabilizers showed no wear it was rerun on the next BHA. The average ROP for the run was 98 ft/hr. The bit was graded 6- 4- CR- C- X- I- WT -PR. BHA 6 (5740'- 6940'MD) Drilling Run The objective of the run was to do the 4° /100 curve TD. This objective was accomplished. The BHA was a Smith MSi616 with 6 x 13's, Xceed 675, ARC, MWD, ADN675, 9 1/8" stabilizer, 1 NMDC, 6 HWDP, 6 1/2" jars, 11HWDP. The drilling parameters were 120 to 160 RPM, 5 to 12K WOB, and 650 to 750 GPM. The Xceed generated the required DSL with out any problems. A setting of 60% gave around 4 DLS while dropping angle. After the run all stabilizers came out with the same OD as they went in with. The D3 sand did not look that good so the decision was made to cement the well back and do the D2 lateral. The average ROP for the run was 63 ft/hr. The bit was graded 1- 1- CT- N- X- I- ER -TD. BHA 7 (4236'- 6940'MD) Cement Run BHA was used to set four cement plugs for the D2 sidetrack. BHA 8 (4236'- 4236'MD) Drilling Run The BHA was a Smith MSi616 RR1 with 6 x 14's, Xceed 675, ARC, MWD, 9 1/8" stabilizer, 1 NMDC, 6 HWDP, 6 1/2" jars, 11 HWDP. The drilling parameters were 80 to 100 RPM, 2 to 6K WOB, and 650 to 750 GPM. Cement wasn't set. POOH to re- cement. The bit was graded 1- 1- CT- N- X- I- ER -TD. BHA 9 (4000' - 4660'MD) Cement Run BHA was used to set cement plugs for the D2 sidetrack due to bad cement on last plug of BHA 7. BHA 10 (4043' - 4438' MD) Drilling Run The objective of the run was to kick off a cement plug and land in the D2 sand with 5 DLS. This objective was not successful. Page 2of5 • 1 • The BHA was a Smith MSi616 RR2 with 6 x 14's, Xceed 675, ARC, MWD, 9 1/8" stabilizer, 1 NMDC, 6 HWDP, 61 /2" jars, 11 HWDP. The drilling parameters were 120 to 160 RPM, 5 to 12K WOB, and 650 to 750 GPM. The Xceed tool started out with the tool in neutral to drill the cement plug, which it rotated off of while in neutral. Tool was then put into HS @ 70% for 44' to make sure we were off of plug. The next command was 84L @ 90% 1 stand, this DLS was a 2.88. After the survey the tool was put into 72L @ 100% and monitored. Next survey showed a 4.86 DLS and we needed 6 DLS to land at this point. TOOH for insufficient DLS, no other PDC bit was available so the decision was made to pick up a motor and mill tooth bit. The average ROP for the run was 77 ft/hr. The bit was graded 2- 2- WT- A- X -I -CT -BHA BHA 11 (4438'- 5105' MD) Drilling Run The objective of the run was to land in the 02 sand with 6 DLS. This objective was not successful. The BHA was a Smith FDS+ with 3 x 18's, PDM 7:8 -5.0, 9 1/8" stabilizer, ARC, MWD, 1 NMDC, 6 HWDP, 6 1/2" jars, 11 HWDP. The drilling parameters were 50 to 60 RPM, 8 to 22K WOB, and 580 GPM. BHA was giving desired response and larger DLS than expected, however around 5075' the BHA started to torque while rotating and would not slide, and showed no differential getting to the bit while sliding. The ROP dropped off while rotary drilling however we did have differential pressure. The decision was made to make a wiper trip and see if it was a hole cleaning issue. Two tight spots were found on the trip resulting in back reaming. First one was 4752' which had a DLS between 6.7 and 6.8. The second one was from 4580' to 4536' which is where the 9.0 DLS from the initial motor slide was located. On the trip in and following trip it was not a problem. The average ROP for the run was 37 ft/hr. The bit was graded 4- 3- WT- 3- E- 2- ER -ROP BHA 12 (5105' -5684' MD) Drilling Run The objective of the run was to land in the D2 sand with 5 DLS. This objective was not successful. The BHA was a Smith MSi616 RR3 with 6 x 14's, Xceed 675, ARC, MWD, 9 1/8" stabilizer, 1 NMDC, 6 HWDP, 6 1/2" jars, 11HWDP. The drilling parameters were 120 to 140 RPM, 6 to 15K WOB, and 650 to 750 GPM. The Xceed was put into 12L @ 100% once we got back to bottom, and the resulting DLS was a 6.7. Tool was then put into 18L © 100% and drilled from 5215' to 5386' with a DLS of 6.8. This had brought us 20' high to plan so the Xceed was put into 36L @ 80 %; this resulted in a 4.71 DLS. The Xceed was then put into 72L @ 40% to get some left hand turn and help keep the nose up. The Xceed inclination showed it was still building at this setting. Xceed was then set to neutral and rotated from 5575' to 5620' while in neutral. At 5620' the Xceed inclination showed a slight drop so the tool was put back into 72L @ 40% and monitored to 5649'. At 5649' the Xceed inclination did not show any build that was observed previously from the same setting. Xceed was then put into a 12L @ 90% and held there until 5671' were the Xceed inclination did not show any build. Xceed was then put into 100% steering to get needed build rate, this resulted in a 5.3 DLS while needing 6.5 to land. The average ROP for the run was 34.4 ft/hr with the last 100' drilled slowed down to 8' to 15' / hr ROP. The bit was graded 5- 4- RO- A- X -I -HC -BHA. This bit had been run with previous runs and pulled before due to bad DLS when required, client was aware of this BHA 13 (5684- 5800' MD) Drilling Run The objective of the run was to land in the D2 sand with 7 DLS. This objective was not successful. Page 3 of 5 ID The BHA was a Smith FDS+ RR1 with 3 x 18's, Xceed 675, ARC, MWD, 9 1/8" stabilizer, 1 NMDC, 6 1/2" jars, 2 HWDP, 8 STDs DP, 11HWDP. The drilling parameters were 80 to 100 RPM, 10 to 15K WOB, and 650 to 750 GPM. The Xceed was run it with a used milltooth from previous BHA 11. Xceed inclination was closely monitored while drilling and the client was informed when the needed DLS from the Xceed was not achieved. Client decided to drill ahead to target and set casing at what ever angle we managed to achieve. Casing point was reached @ 5800' with a projection 79.65 angle at a TVD of 4538'. The average ROP for the run was 16.6 ft/hr. The bit was graded 5- 4- WT- 3- E- 2- ER -ROP. BHA 14 815 (0'- 5788' MD) Casing cleaning runs BHA 14 was a dumb iron BHA used to clean out the casing to the float collar BHA 15 was a scrapper and magnet BHA to clean out casing for USIT log run. BHA 16 (5800' - 5830' MD) Drilling Run The objective of the run was to land in the D2 sand with 4 DLS. This objective was not successful. The BHA was a Hughes HCD505ZX with 2 x 12's,2 x 14's, 1 x 10, PDX5 475, Impulse MWD, VPWD, 475ADN, 6" stabilizer, 1 NMFDC, Well Commander CCV, X/O, 4 3/4" jars, 2 HWDP, 26 STDs 3 1/2" DP, 15 jts 4" HWDP. The drilling parameters were 80 to 100 RPM, 6 to 20K WOB, and 230 to 275 GPM. The PDX5 was run into the casing and drilled the float collar, no cement was found between float collar and shoe track. Shoe track was drilled with no issues and no cement was drilled between shoe track and bottom of 9'/." well bore. PDX5 was put in to 100% steering HS for the needed 4 DLS to land at the top of the D2 sand. ROP was between 3' and 15' per hour. After drilling to 5820' and performing the FIT, we continued to drill to 5830' where it was decide to TOOH to check the bit. On surface the bit was found to have the size 10 jet packed off with a combination of cement, siltstone, and sand. The average ROP for the run was 8.1 ft/hr. The bit was graded 0- 0- PJ- C- X- 0- CT -ROP. BHA 17 (5830' — 7520' MD) Drilling Run The objective of the run was to land in the D2 sand with 4 DLS. This objective was successful. The BHA was a Hughes Smith MS1613 with 6 x 12's, PDX5 475, Impulse MWD, VPWD, 475ADN, 6" stabilizer, 1 NMFDC, Well Commander CCV, X/O, 4 3/4" jars, 2 HWDP, 26 STDs 3 %" DP, 15 jts 4" HWDP. The drilling parameters were 80 to 140 RPM, 6 to 10K WOB, and 230 to 275 GPM. The max build that the PD generated was 5.5° /100. The inc hold worked well the entire run. The average ROP was 55.78. The bit was graded 1- 1- BT- S- X- I- NO -TD. The short trip and the trip out of the hole was made without any problems. Lessons Learned 17 1/2" Surface Hole 1. Strong right hand walking tendency in surface hole here. 2. Gyro -pulse saves a lot of rig time compared to wireline gyros. 9 1/4" Intermediate Hole Page 4 of 5 • 1. On the bit trip the MWD and LWD tools were downloaded on the trip out of the hole. This proved to take longer than laying them down and picking them back up. Next we will just lay them down and pick them back up. If they end up waiting for the toots to be downloaded they can service the rig. 2. Exceed is a good tool for the Cook Inlet. It produced 4 DLS on one PDC run, 6 on another PDC run, and 4s and 6s on a mill -tooth run. Exceed is superior to a motor for drilling coal because rotation is critical to clean the coal cuttings. We were unable to slide with a motor, presumably because hole - geometry caused a stabilizer to bind into a keyseat. We used the same mill -tooth bit to drill 200' with Exceed that had been pulled from the unsuccessful motor run. X -5 probably would not have achieved the same DLS as Exceed. 3. The Xceed tool will give a better DLS in soft formations with slightly lower GPM and slower rotary. The DLS while drilling the coal with 750 GPM was a 3 and after dropping the GPM to 650 it increased to a 4 DLS. 4. Need to be sure to gauge all stabilizers / wear bands in BHA on the way out or the way in ever time the BHA is tripped and record wear so we can monitor the changes. 6 1/8" Production Hole 1. PDX5 ran with no issues, formation has a definite left hand walk, 25% right just barely held it at times. 2. Page 5 of 5 Chevron Drilling & Measurements I OW 2525 Gambell Street.

This direction and inclination was projected from the final survey point to TD, which resulted in the following bottom -hole coordinates: Measured Depth: 6940.00 feet True Vertical Depth: 5105.78 feet Displacement at Azimuth: 728.95 feet at 10 degrees M -10: The final MWD survey point was located at 7484.09 feet with an inclination of 89.49 degrees and an azimuth of 2.99 degrees. This direction and inclination was projected from the fmal survey point to TD, which resulted in the following bottom -hole coordinates: Measured Depth: 7520.00 feet True Vertical Depth: 4555.87 feet Displacement at Azimuth: 1427.01 feet at 10 degrees Formation Evaluation 17 -1/2 inch surface Section The surface section was drilled from 480 to 1442 feet in one run. A motor was used for directional control. A GyroPulse* was used for surveying due to high magnetic interference from nearby casing to provide Gyro While Drilling operations. VISION* Service Resistivity, Gamma Ray, and APWD were also supplied in real -time and from memory once the tools were retrieved. After the surface hole was drilled, 13 3/8 inch casing was set. The final measured bottom -hole temperature was 94.12 degrees Fahrenheit. 9 -1/4 inch Intermediate Section (PB1 Pilot Hole) The intermediate section was drilled from 1442 to 6940 feet in two runs. The BHA used for this section included MWD, LWD (VISION* Resistivity, Gamma Ray and Neutron Density), and the Xceed rotary steerable tool. At 5740 feet, the decision was made to trip out for a bit change. The pilot hole was then completed with a new bit to 6940 feet. Real time and recorded mode data was provided in order to decide which sand to place the horizontal production section in. The final measured bottom -hole temperature was 134.6 degrees Fahrenheit. 9 -1/4 inch Intermediate Section (M -10 Sidetrack) This section was drilled from 4043 to 5800 feet in 5 runs. The first run was aborted due to poor cement quality. The remaining runs were drilled with MWD and LWD (VISION* Resistivity and Gamma Ray) tools. Three of these were drilled with the Xceed rotary steerable tool. On the second of these runs, it was decided to use a PowerPak* mud motor in order to achieve the required dogleg. Both PDC and Milltooth bits were used for these runs and were changed according to needs and availability to achieve the desired results. The final measured bottom -hole temperature was 114.4 degrees Fahrenheit. 2 • Chevron Schlumberger 6 -1/8 inch Production Section (M -10 Lateral) The production section of the well was drilled from 5800 feet to 7520 feet in one run. PowerDrive* rotary steerable tool was used for directional control during this hole section, providing Gamma Ray and Inclination at bit. VISION* Service Resistivity, Gamma Ray, PWD, Azimuthal Density, and Neutron Porosity were supplied in real -time. These services included borehole density images in real -time used by the DCS Well Placement engineers for picking formation dip angles. The final measured bottom -hole temperature was 118.4 degrees Fahrenheit. Innovation & Lessons Learned Borehole Density Images were provided in real time for well placement purposes. Formation dip angles were determined from these images. This data was transmitted via the internet to Schlumberger's InterAct service which allowed real time monitoring of the drilling data by engineers in town, as well as by the rig site geologist. In preparation for the production lateral, some difficulties were experienced with the azimuthal system in the Density Neutron tool. Both primary and backup tools were experiencing external magnetic interference from a combination of steel on the deck and possibly from MiSwaco magnet tools nearby. The lesson to take away is that if we experience this problem in the future, we can lift the Density Neutron with the crane to eliminate the effects of external magnetism in order to continue successfully with tool preparation. Schlumberger Oilfield Services Drilling & Measurements appreciates the opportunity to provide Chevron Exploration (Alaska) Inc. with MWD and LWD services.

OBJECTIVES M -10 is a development well that extends to the east from leg A -1 on the Steelhead Platform. Its primary targets are the Grayling Sands from the B -1 extending through to the D -06 sands. The target location is a shallow horizon that has little departure from the platform. The well design has a high angle pilot hole being drilled through the D -06 sand to evaluate the best sand package to target for a horizontal completion. Based on analysis from the MWD logs, a choice of the best productive sand will be chosen for a 1400' MD horizontal section to be drilled. The horizontal will be completed with open hole screen. 2.2.
