(rajv) (RayVaussim); Nienhaus, Doug R Subject Steelhead M -18 BOP test variance Winton, As discussed on the phone we are planning to re -start operations on the Steelhead after a six month delay waiting on a new work boat. M has been in an operational shut down status since January with a 3 1/2" kill string hung off. The well has not yet been perforated and thus we are seeking a variance which would allow us to perform an initial shell test on the BOP stack prior to pulling the kin string. After pulling the kill string a full function BOP test would be performed prior to running in the hole with the welbore cleaning tools. By performing a shell test instead of a full function test would erate having to test against a tubing hanger instead of a BOP test plug. Performing the full function BOP test after the kill string has been pulled would also reduce the operational logistics involved by eliminating the crossovers from 3 1/2" tubing back to 31/2" DP and 5" DP for the required pipe ram tests. Based on the fact the well is fined with kill weight fluid and has yet to be perforated, we do not feel there is an inherent risk with our proposed procedure. Please contact me at your earliest convenience if you require any additional information pertaining to this variance request.

Safe and efficient operations are no longer possible due to the hazardous ice conditions in Cook Inlet and the loss of the MV Monarch support vessel. Union Oil Company plans to resume operations approximately April 15, 2009 pending progress on • other work and the location of a suitable support vessel. We will file the required well records within 30 days pursuant to 20 AAC 25.072. The proposed configuration of the wellbore can be seen on the attached wellbore sketch. The 9 5/8" casing x 7" liner was jug tested to 3000 psi for 30 min on 1/23/09. The well bore is planned to be displaced to seawater and a kill string run to approximately 2768' within the next 72 hrs. A tree will be installed and the wellbore will be made secure until operations resume. Attached please find a basic procedure, well sketch, and form 10-403 in duplicate.

Subject: RE: Steelhead M -18, PTD 208 -162 Morning Tom, The remedial cementation on the 7" liner appeared to go well - we estimate 59 bbls behind pipe - we believe we lost 6 bbls towards the end of the job. Job was planned on 30% OH excess and in fact we pumped a few barrels more (70 bbls pumped). The only cement we saw came from the residual cement purposely left in the stinger - no cement above the lengthy liner lap (top at 4550 ft MD • 9 -5/8" shoe at 6120 ft MD). This leads us to believe we have got a pretty reasonable job, no doubt aided by liner being centralised and we obtained an unhindered circulating rate of 5 BPM @ 870 psi after perforating liner below cement retainer set at 7100 ft MD. Forward path is polish the PBR - currently in hole doing this. Then separate trip to set the ZXP liner top packer. Then test cased wellbore against cement retainer to 3000 psi.

I have passed this note on to my geological and reservoir colleagues responsible for the Inlet. It is unfortunate that the liner got stuck high and Unocal /Chevron has made good faith attempts to get the pipe to the desired depth. However, the resource must be considered in the path forward. What is the present schedule on the well work? I likely won't be in the office much longer today, but will check email from home and you can also reach me on my cell at 529 -1645.

Subject: RE: Steelhead M -18, PTD 208 -162 Afternoon Tom, With reference to your question on drilled reservoir that we will not be capturing, in completing well M -18 after the liner running tool failure. The C3 appears to be the best pay left below the 7" shoe. The B5, B4, and B1 are also present below the 7" shoe, but not as promising. Unfortunately due to sticking problems we had to eliminate gathering reservoir pressures in the 8 -1/2" hole section, after almost getting stuck with the TesTrak on our first pressure point in the A2 sand. The A2 sand pressure was very close to the pressure data point that was recorded in Well M -17. Based on the poor mud log shows in the A2 sand and all the other sands below the 7" shoe with the exception of the C -3 sand, we are assuming these sands have seen significant depletion from other wells completed in these zones. There is the potential for crossflow and it was a point of consideration in our decision. However if crossflow were to occur it would be going into gas zones that are currently being produced in existing gas wells and the gas theoretically would be recovered. I hope the above addresses your queries.

Prior to leaving the office I did apprise Commissioner Foerster of the situation and she gave her oral approval for you to proceed with the cementing operation. You indicate that the C3 sand is potential pay but now lies 1000' below the 7" shoe. Are there other potential pays in the interval below the 7" shoe? Is there any chance of cross flow between intervals? I look forward to your reply.

A brief well history follows: • The well was drilled and cased to 1441 with 13 3/8 surface casing. The casing was cemented successfully in 2 stages. • The well was then drilled to 89 deg and back to 63 deg where the 9 5/8 intermediate casing was cemented to 6120. The casing was cemented successfully in 2 stages. • Drilling of the 8 1/2 section was completed to 9930' MD @ 63 deg. Hole conditions were questionable at the completion of drilling operations. Losses were noted at 8190' The BHA was backreamed all the way back to the 9 5/8 shoe. • A 7" liner was run to the B2/B3 coal at 8303 but could not be worked deeper. • The liner was pulled and a clean out run made. Packing off of the drill string was evident but eventually cleaned up. • A 2nd attempt was made to run the liner with rotary capability. The liner was worked with difficulty past the B2/B3 coal and to 8420' but was packing off and could not be worked deeper. It was worked back to 8375 where the liner running tool failed. This left the liner top @ 4545 and the shoe at 8375. • Evaluation of the logs indicates substantial pay behind the 7" liner and 9 5/8 casing. The C3 sand, which was potential pay is left at 9400' (below the 7" shoe). • After many hours of evaluation, we conclude that the best option is to cement the liner in place and continue with completion operations. Hole conditions deteriorate below the B coal at 7500' and the shoe is likely packed off completely at this point. Therefore we would like to cement the liner from 7100' which gives us the best chance of covering pay and not packing off during cementation. The procedure forward would be as follows: • Run and set 7" retainer at 7100. This tool has a small perforating gun below it. Set retainer and fire gun. • Establish circulation past liner hanger. • Cement liner with 64 bbls slurry. (30% OH excess and 1375' of lap) • Circulate clean • Run polish mill and polish tie back sleeve. • Run and set ZXP liner top packer • Test casing and liner to 3000 psi. • Swap the wellbore to completion brine. • Proceed with GP completions Attached you will find a proposed wellbore sketch. Some of the completion details are not yet determined but the pertinent information for the issue at hand is noted on the drawing. Also attached is a copy of the unregistered well survey and planned trajectory. Please indicate you concurrence with the proposed plan by return email if you find it acceptable.

If they were ok, then just an email saying that AOGCC's calculated coordinates are apparently incorrect. A stat tech brought this surface coordinate discrepancy to my attention yesterday. I initially thought that there might be a problem with AOGCC's coordinate conversion software, so I spent time thoroughly cross - checking our results. After checking our results using two other conversion programs, AOGCC's calculations appear to be correct and consistent. So, I pulled out a 1993 book titled "Platform Information, Cook Inlet, Alaska" by Belmar Engineering. This book has specs on all Cook Inlet platforms, including Steelhead, and it has listings of conductor coordinates in X,Y format. Only a few of these conductors have associated well names, but luckily the conductor B2 -3 is labeled as containing the TBU M -2 well. The surface coordinates for M -2 are 603 FWL and 1043 FNL. So, the X coordinate from the west section line for TBU M- 18 should be more like 607' FWL rather than the 377' FWL value shown on the M -18 permit application. That's why I thought I'd check with you to see if the 377' FWL value might be a typo or cut and paste problem.

One of the sections was returning a northwest vertex that was not the corner, but was actually east of the corner. This, in effect, moved the western boundary of the section to the east, which shortened the FWL distances. I did a temporary fix by removing that vertex. Now I have to go in and adjust the code to deal with this situation in the future. Sony for the problems.

(rajv) (RayVaussine) Subject: M -18 permit Tom, I am in receipt of the M -18 permit. Thanks. The testing requirements are noted as 250/3000 for the rams and 250/2000 for the annular. 18AAC 25.035 (e)(10)(A) indicates a test pressure of 50% of rated working pressure for annular preventers. Though I understand the issue with M -18, I would request that we prove the system by testing the annular to 2000 the first time and then a lower pressure on subsequent tests. A 21 1/4 2M annular is a large preventer and the fatigue caused by regular 2000 psi tests on 5" DP will likely shorten element life considerably. If you are receptive to this, please advise of subsequent test presssure requirements for this annular.

All of the intended completion intervals for the M -18 well fall below the 9 5/8 casing shoe. Per your request, I have indicated the producing intervals of the nearest 2 wells that are producing from or are capable of production from the same intervals as the intended completion in the M -18 wellbore. For reference, I also plotted a circle encompassing 10 acres which is the required spacing pursuant to Conservation Order 228. As you can see, K -20 is the only wellbore to fall within the 10 acre spacing along the intended trajectory of M -18. K -20 is incapable of production from equivalent strata. Therefore, a spacing exception should not be necessary to drill M -18. If you have any questions, please don't hesitate to contact myself or Jim Rose at 907 - 263 -7637. Sincerely, Timothy C.

Drilling operations are expected to commence approximately December 1, 2008 depending on the progress of other ongoing projects. 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 -18 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. 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 section of M -18 is planned to be drilled with a 17 % /2" bit. Union Oil Company of California / A Chevron Company Page 1 of 2 • • In accordance with 20 AAC 25.050 (b)(2)(B)... Union Oil Company of California is the only operator of wells within 200' of the planned trajectory of M -18. 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. The remainder of the requirements of 20 AAC 25.005 are attached for review or are on file with the Commission.

With the exception of M -9, all wells pass major risk criteria. M -9's closest approach is behind the conductor of M -18 and improves with depth below the conductor shoe. Collision risk will be mitigated procedurally by monitoring annular pressures of adjacent wellbores and placing an observer in the wellhead room to listen for indications of a collision.

Mud weight: Maintain the 9.0 — 9.2 ppg density or as directed. 2. Rheology: Maintain a YP between 25 -35 or as needed to achieve adequate hole cleaning. 3. Filtrate control: Maintain the filtrate <10 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 1 -2 ppb BAROFIBRE and 1 -2 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, 9 ppb Barofibre, 9 ppb Wallnut F, and 12 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 or Barolift is recommended. Run DFG (Drilling Fluid Graphics) to confirm hole cleaning efficiency based on current rheology, flow rates, angle and cuttings size. Sweep Formulation: 25 bbl of mud with -1 ppb of Barazan D added or 0.25 ppb of Barolift. Dextrid and /or PAC L should be used for filtrate control. While drilling, monitor the torque and drag to determine if liquid lubricant is required. 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 - 9.0 range with caustic soda. Daily additions of Aldacide G / X -Cide 207 should be made to control bacterial action. M -18 v1.0 2 8/25/08 • • Halliburton BAROID Chevron Mud Program At TD, a Wallnut "flag" (30 bbl pill with 15 ppb of Wallnut Fine) should be pumped to gauge hole washout and to calculate the required cement volume. Spot the above LCM pill in the bottom of the hole. If it has been used, mix a duplicate pill to spot on bottom. 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. Losses have historically occurred in this interval. Ensure that the mud weight is maintained in the 9.1 -9.2 ppg range through this area. 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). Spot the above LCM pill in the bottom of the hole. If it has been used, mix a duplicate pill to spot on bottom prior to running casing. Reduce system YP with Barathin as required for running casing as allowed (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 < 20 (check with the cementers to see what yp value they have targeted). Consider spotting a Steelseal LCM pill prior to running the 13 -3/8" casing if losses have been seen in this interval. The plug will again 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 1000 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-3 600 800 1000 80 rpm 69 92 119 100 rpm 72 96 123 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 or Barolift sweeps to enhance hole - cleaning efforts. Monitor sweep effectiveness. • Successfully land and cement casing.

Rheology: Maintain a YP between 13 and 20. Pump high viscosity or Barolift sweeps throughout the interval as needed, particularly prior to POH for casing. Optimized mud rheology and flow rate will be the primary mechanisms for achieving hole cleaning in this deviated wellbore. Maximize pipe rotation (ideally > 100 RPM). 3. Other issues: The use of good drilling practices to minimize excessive swab and surge pressure should be employed to minimize the chances for losses and differential sticking. Operations Summary: Mix a -50 bbl LCM pill prior to drilling out. The pill formulation will be the 70 ppb pill from the LCM tree. Mix the recommended LCM material in thinned back base mud. Drill out the cement/casing with the existing mud system. Soda ash and citric acid should be used to pretreat for any negative effects of the cement. After obtaining a leak off, begin drilling ahead displacing to the KCI based fluid. Baracarb 5, 25 and /or 50 should be strung into the system at 4 -8 sx/hr for losses. Barofibre can be added to this mix. The Clayseal concentration should be 1 ppb in the initial mix. As the mud shears, slowly raise the Clayseal concentration to its full 4 ppb concentration. 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 or Barolift sweep is recommended. Sweep Formulation: 50 bbl of mud with -1 ppb of Barazan D added or .25 ppb of Barolift. Dextrid and PAC L should be used for filtrate control (6cc range).

Maximize rpms at all times. ROPs above these levels or with no rotation (sliding) or low rpm will require an increased frequency of the following remedial hole cleaning practices: • extended periods of circulation (with maximum pipe rpm, targeting > 100 rpm) • hole cleaning sweeps (change flow regime of base mud by using fibers, density or rheology for carrying capacity) • connection practices - employing extended gpm, rpm and back reaming during the connection M -18 v1.0 5 8/25/08 • • • Halliburton BAROID Chevron Mud Program 8 -1/2" Hole Recommendations (7" liner) to 9970' Mud Type: 2% KCI, Clayseal, GEM Properties: Densi Viscosi Plastic Viscosi Yield Point API FL • H 6250' — 9970' 9.2 -9.3 40 -53 6 - 15 13 - 20 <5 8.5 -9.5 System Formulation: 2% KCI, Clayseal, GEM Product Concentration Water 0.905 bbl KCI 7 ppb (8 -9 K chlorides) Caustic 0.2 ppb (9 pH) Barazan D 1.0 ppb (as required 18 YP) Dextrid 1 -2 ppb Clayseal 4 ppb Aldacide G 0.1 ppb GEM GP 1.5% by volume Baracarb 50 10 ppb Baroid as needed Mud Type: 9.2 ppg KCI /Clayseal /GEM System. 1.

Follow the hole cleaning guidelines to assist in drilling parameter selection. Use connections for high RPM and pump rate support when these parameters are limited during drilling operations. • Follow the coal drilling guidelines. Coal Drilling The following lessons were learned from extensive experience drilling coal seams in Cook Inlet. The hole stability risks when drilling coal seams are often high, and the fluid design and drilling operations have been optimized to combine reduced risk with reduced costs. The need for good planning and drilling practices is also emphasized as a key component for success. • Keep the drill pipe in tension to prevent a whipping effect which can disturb coal sections. • Use asphalt -type additives to further stabilize coal seams. • Increase fluid density as required to control the running coal. • Emphasize good hole cleaning through hydraulics, ROP and system rheology. In the event that sloughing coal is encountered, consider spotting a 30 ppb BAROTROL pill across the coal seam. The pill can be safely "squeezed" into the coal by closing the bag and applying pressure not to exceed the total annular pressure loss (based on ECD values using the DFG software). System density increases can also be employed in increments of 0.5 ppg. Solids Control Equipment Maximize the use of all solids control equipment to ensure that the solids content of the system is kept to a minimum during this interval. 1. Run the shale shakers with as fine a screen size as possible. • Size shakers screens with coarse mesh initially • Adjust screen size as solids loading, mud rheology and flowrates allow • Inspect the shakers frequently, taking time to repair / replace damaged screens 2. Maximize the use of the centrifuge, keeping the fluid as clean as possible. Running Casing / Cementing Preparation Monitor hole fill /returns closely while running the liner to insure losses haven't occurred. Refer to Baroid's DFG+ program if calculated surge /swab values are needed. Condition the mud prior to the cement job. Completion The well will be completed with a 3% KCI brine. If rig ops allow, bump the plug with the brine, then finish displacing the casing after coming off the liner hanger. M -18 v1.0 7 8/25/08 Chevron • •teelhead Platform 4110 Well M -18 %10.

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 -9, M -2, M -3, M -4 are all critical close approach wells. Record annulus pressures on these wells prior to spud and monitor during the drilling of the surface and 1St intermediate hole sections. 12 - 1/4" Hole Sections • Shallow gas sands will be encountered that have the potential to flow and cause a loss of well control. 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. 8 - 1/2" 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.
