It is thought the perforations have been plugged due to near wellbore formation damage. The proposed wellwork plan is to stimulate the open perforations in the Tyonek 40 sand with acid to remediate/remove near wellbore formation damage. Summary Procedure 1. MI RU CTU and pump equipment,test Quad BOP to 250psi low/4,000psi high. 2. Set coil tubing packer above T 40 to isolate from T10 and T 17 sands. Pressure backside of CT to 1000 psi with nitrogen. 3. Establish pumping rate and pressure with 5%Ammonium Chloride water. 4. Begin pumping acid job as follows: a. Acetic Acid preflush b. 9-1 Gas Well Mud Acid c. 9-1 Gas Well Mud Acid d. Acetic Acid spacer 5. Displace with nitrogen to perforations. 6. Shut down acid pumps for ISIP, 5 min SIP and 10 min SIP. 7. Equalize pressure across coil tubing packer with nitrogen and release packer. 8. Bleed off pressure on tubing and unload well with nitrogen assist as needed. 9. .Turn well over to production.

The well was tested in several deep Tyonek zones (T -130, 140, & 150), resulting in low rates. These perfs were isolated with a CIBP in May 2004 and the well was perforated in the T -81 & 100 sands. The results showed the T -81 to be wet and the well remained shut in until late 2011. The existing zones were isolated and the T -10, 17, & 40 were perforated with no indications of flow. The well remained shut in and built to 1,385psi SITP over a one year buildup. The well was blown down to production during diagnostic testing and began flowing at "150Mcfd for one week until it died. It is thought the perforations have been plugged due to near wellbore formation damage. di The proposed wellwork plan is to stimulate the open perforations in the Tyonek 10, 17, & 40 sands with acid to • remediate /remove near wellbore formation damage pep :orations Procedure firms �" 1 1.

The current wellbore schematic is attached. The well has remained shut in, unable to sustain flow, since June 2004. Bottomhole pressure was measured at 3660psi in June 2004 while holding "830psi surface tubing pressure. Current tubing pressure is 940psi. Objective: The primary objective is to add perfs in HV -3 and produce at a sustainable gas rate. Nitrogen will be used to displace the current water in the wellbore back into open perforations. A plug will be set above the open perfs. Perfs will continue to be added up -hole until sustainable flowrates are obtained. HV -3 - has no flowline, so it will be tested through HV -11's flowline to the test separator. HV -11 is currently shut in. Procedure: 1. Prep location and pad for test through HV -11 flowline. 2. Establish fluid level (FL) with echometer. 3. MIRU nitrogen equipment. Displace fluid back into open perfs with nitrogen. RD. 4. RU E -line and set plug at "9150'md (above T -81 perfs). 5. Perf T -40, 8140- 8180'MD. RD E -line and Test. a. If gas rate is sustainable ( >500mcfd) continue to flow for 24 hours. RDMO equipment. b. If no flow to surface, establish FL with echometer. c. If FL is apparent ( >500' above open perfs), displace fluid back into open perfs with nitrogen and set plug above open perfs. d. If no FL, formation is likely too tite to flow, no plug is necessary, move uphole and perf next potential zone. 6. Repeat step 5 for all potential zones until sustainable flow ( >500mcfd) is attained. Below are ALL potential add perf zones to be tested if necessary.

Weatherford did not send complete tool to pull plug. Ran in the hole with an overshot dressed with a 1-11/16" grapple and attempted to pull the plug, no success. Pulled out of the hole. Appeared that the plug was entering the overshot but a short catch grapple was needed to engage the plug. Waited on short catch grapple. Rigged down and moved equipment to allow coiled tubing to rig up on the well. Rigged back up on the well. Ran in the hole with the complete Weatherford pulling tool and pulled the bridge plug out of the hole. Rigged down the slick line unit. Waited for coiled tubing crew to return to location. Function tested the coiled tubing equipment and stabbed the injector head. Mixed the diesel with 5 gpt W-23 non emulsifier in the batch tank. Displaced the reel with diesel and tested the BOP equipment to 200 psi low and 5000 psi high. Cut off the connector head and picked up the Weatherford packer assembly.

Ran in the hole and tagged up on the wireline bridge plug at 10513' to confirm depth counter operation. Pulled out of the hole to 10050' and set the packer. Pumped data frac into T-140 perfs from 10154' to 10168' as follows: 24 bbls of diesel at an average rate of 0.8 bpm at 6000 psi. Reduced the rate to 0.6 bpm after pumping 17 bbls due to pressure. Pumped the last 7 bbls at 0.6 bpm at 5550 psi. Shut down with an ISIP of 3768 psi. Monitored the well. The shut in pressure fell to 1792 psi. Bled the pressure off and released the packer. Allowed the pressures to equalize. Pulled out of the hole with the coiled tubing maintaining 600 to 800 psi on the annulus with the fluid pump. Rigged up the slickline unit. Ran in the hole with the Weatherford pulling tool and latched onto the bridge plug at 10513'. Equalized the plug and pulled the same out of the hole. Rigged down the slickline unit. Rigged up the coiled tubing unit and stabbed the injector head. Tested the lubricator. Ran in the hole with the packer to 10522'. Set the packer. Pumped data frac into T-155 perfs from 10640' to 10678' as follows: 24 bbls of diesel at an average rate of 1.2 bpm at 5550 psi. Shut down with an ISIP of 2700 psi. Monitored the well. The shut in pressure fell to 1649 psi. Bled the pressure off and released the packer. Allowed the pressures to equalize. Pulled out of the hole with the coiled tubing maintaining 700 to 1000 psi on the annulus with the fluid pump. 5/14/04 Finished pulling out of the hole with the coiled tubing maintaining 700 to 1000 psi on the annulus with the fluid pump. Layed down the packer and setting tool and picked up the jet nozzle. Layed down 3 riser joints and stabbed the head. Tested the lubricator and blew the reel dry with nitrogen. Ran in the hole with the jetting assembly to 10700' stopping every 2000' adding 750 psi to coil to maitain a differential pressure of less than 1500 psi per Schlumberger specifications. While trying to pressure up to 3750 psi at 10000' the pressure started to increase in the annulus and drop in the tubing. Bleed annulus and began jetting the well with Nitrogen at a rate of 250 scf per minute. Increased the rate to 500 scf per minute and finished jetting the well. Recovered a total of 71 bbls of diesel. Troubleshooted coil problems and evaluated options to proceed. Decision was made to pull out of the hole to inspect the coil for a possible hole. Pulled out of the hole with the coiled tubing visually inspecting the same. Displaced the reel with 34 bbls of diesel and pulled the head. Broke off the jet nozzle and made up the test sub. Tested the coiled tubing to 200 psi low and 5000 psi high, good test. Broke off the test sub and made up the jet nozzle. Stabbed the injector head and tested the break to 5000 psi. Displaced the reel with nitrogen. Opened the well with a tubing pressure of 1150 psi. Ran in the hole with the coiled tubing to 10700' maintaining 1200 psi on the annulus. Began jetting the well with Nitrogen at a rate of 600 scf per minute with 1128 psi on the tubing maintaining 750 psi on the annulus with the choke for 40 minutes. Increased the rate to 800 scf per minute with 1370 psi for 24 minutes. Increased the rate to 900 scf per minute with 1617 psi for 47 minutes. Shut down after pumping a total of 950 gallons of nitrogen. Recovered a total of 5 bbls of diesel (76 bbls total). Pulled out of the hole to 9800' and prepared to flow test the well. The shut in tubing pressure was 1005 psi and the shut in casing pressure was 911 psi. Opened the well up to the testers adjusting the choke to maintain 750 psi backpressure. Tested the well with coil in the hole simulating a velocity string. Well was unloading nitrogen. 5/15/04 Well flowing back nitrogen then died. Would not flow against the 750 psi of back pressure. Reduced the backpressure to 250 psi and then well resumed flowing. After 15 minutes had burnable gas at the flare. Flow decreased flow from 788 Mcf/d to 108 Mcfld of intermittent flow. Continued to flow the well while waiting on a fluid level machine. Attempted to shoot fluid level, there was too much interference to see fluid. Pulled out of the hole with the coiled tubing. Rigged up Pollard and shot the fluid level, fluid level was at approximately 9000'. Secured the well and rigged down the Schlumberger coiled tubing equipment.

Ninilchik]] " -- Tom Maunder, PE AOGCC Mr. Yezierski, The Unocal development you are referring to is called Happy Valley and is within the Deep Creek Unit administered by the State Division of Oil and Gas. The AOGCC has issued permits for 8 wells to be drilled from the same pad located in section 22. According to the information published for these wells, 4 wells reach total depth in section 22 and 1 each in sections 14, 15, 21 and 28. No wells have been proposed for sections 23 or 24. Our regulations do require notice to landowners depending on the distance from the proposed activity. In the case of these gas wells, all owners within 3000' laterally of the well at the production zone should be notified. Although you did not provide the footage distances to the section lines for your property, it would appear that it is likely beyond the 3000' notice distance. If you would like, we can add you to our notice list for any activities that require public notice in this area. You may also explore our web site at www.aogcc.alaska.gov. In the "Orders" section under conservation orders you will find several orders relating to the drilling of the wells at Happy Valley. "Drilling Statistics" would have information regarding when permits are issued or wells are completed. With regard to Unit administration and other land activities, you might contact Ms. Carol Lee at the Division of Oil and Gas. I have included her eddress above. I hope this information is of help.

N 'V fI' (( ~; Q '\¡ Winton; Please be advised that we have begun moving the Kuukpik Rig #5 to the Happy Valley main pad to drill HV Wells #3, #4 & #5. The anticipated spud date is Sunday (+1- 1 day). This e-mail is also intended to notify the AOGCC of several minor changes to our approved General Drilling Procedure. Please be advised that we are planning the following procedural changes for the purpose of optimization: (1) Batch Drilling: The rig package can be safely & efficiently skidded between the three wells, which were permitted T apart, similar to an offshore rig package. Unocal plans to batch drill the three 12 1/4" holes, skidding from well to well, followed by three 8 1/2" intermediate holes, followed by three 6 1/8" holes. The ability to skid the rig and employ batch drilling techniques offers potential cost savings due to; (a~) only PU & LD pipe one time for three wells, (b.) more efficient mud usage (use the spud mud for three sections, the intermediate WBM for three sections, etc.), and (c.) more efficient BHA handling (one BHA potentially can drill three sections in a row). The attached schedule shows when we plan to nipple up and test BOPs for drilling 8 1/2" & 6 1/8" holes. Please note that we do not intend to utilize a diverter, as this requirement has been waived by the AOGCC. «Batch Drill and Test Schedule 1-15-04.mpp» (2) Casing Drilling: We plan to utilize Weatherford's DwC (drill with casing) technology on the 12 1/4" surface holes. Essentially we intend to drill the 12 1/4" hole with the 95/8" casing, using a (PDC drillable) 12 1/4" BBL drill shoe, and then cement the casing to surface as per the approved program. This technique is particularly attractive in a batch drilling environment. In addition, we intend to utilize a KCL-WBM for the 8 1/2" hole instead of the original planned LSND-WBM. This is expected to further minimize waste generation, since less hole washout problems are predicted with the KCL-WBM. Finally, we have 'tweaked' the trajectories of the first two wells, Happy Valley Wells #3 & #4. Although the geologic targets remain the same, we intend to kick off from vertical just below the 9 5/8" surface casing instead of as permitted (below the 7" intermediate casing shoe). Essentially, kicking off shallower shortens the distance to the target, thus reducing the measured depth of the well at the permitted objective location. It also offers minor advantages with respect to collision avoidance. I will 1 of 2 1/27/20044:01 PM Notification of impending spud - Happy Valley Well... . . send you the revised trajectories if you want them. Please let me know if additional information is required or if I can be of service in any way. Thanks. Jerry F. Bowen, P.E.

This permit to drill does not exempt you from obtaining additional permits or approvals required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. A weekly status report is required from the time the well is spudded until it is suspended or plugged and abandoned. The report should be a generalized synopsis ofthe week's activities and is exclusively for the Commission's internal use. The permit is approved subject to full compliance with 20 AAC 25.055. Approval to perforate and produce is contingent upon issuance of a conservation order approving a spacing exception. Unocal assumes the liability of any protest to the spacing exception that may occur. 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. Please provide at least twenty-four (24) hours notice for a representative of the Commission to witness any required test.

Preliminary Mud Program tit e WAIVER REQUESTS Unocal respectfully requests waivers to; (1.) AOGCC regulations 20 AAC 25.035 (C) (2.) AOGCC regulations 20 AAC 25.050 (C)(1) WAIVER #1: Unocal request permission to drill the 12 %" suñace hole to a depth of +1- -*" 1037' without a diverter. AOGCC regulation 20 AAC 25.035 (h) (2) stipulates: (h) "Upon request f the operator, the commission will, in its discretion, approve a variance ...... (2) from the diverler system requirements in (C) of this section if the variance provides at least equally effective means of diverting flow away from the drill rig or if drilling experience in the near vicinity indicates that a diverter system is not necessary. " Based on our experience drilling 12 %" suñace holes in Happy Valley #1 & #2, it has been proven conclusively that no shallow gas hazards exist beneath this pad to a depth of at least 1037' BRT. The 12 %" suñace hole for Happy Valley #3 will be drilled from the same pad as Happy Valley #1 (suñace location +1-70' away), and to the same depth as Happy Valley #1 suñace hole. The Geologist, Dave Buthman, has reviewed the shallow geology and has prepared the following summary of the shallow lithology: From surface to 1037' VD beneath the Happy Valley surface pad, we anticipate the following lithologies: 0-300': interbedded med to coarse grained sand and coarse gravels 300-1037': interbedded light gray silty claystones, argillaceous siltstones, gray silty claystones, light gray fine to medium grained sandstones, with a few thin brown lignitic coals. We do not anticipate any significant faulting, nor do we expect any oil or gas to be trapped, as no suitable seals exist within this shallow section. For the purpose of basic risk mitigation, Unocal will utilize a gellnative spud mud which is expected to weigh approximately 9.3 ppg when drilling at the planned suñace hole TD of 1037', to eliminate the risk of a shallow water flow. e e WAIVER #2: Unocal requests permission to drill the 12 %" surface hole to +1-1037' ¥ without surveying until after the 9 5/8" casing is cemented. AOGCC regulation 20 AAC 25.050 (h) stipulates: (h) ltUpon application, the commission will, in its discretion, waive all or part of the directional survey requirements of this section or approve alternate means for determining the location of a wellbore if the variance at least equally ensures accurate surveying of the wellbore to prevent well intersection, to comply with spacing requirements, and to ensure protection of correlative rights. 11 Due to plans to drill the 12 %" surface hole vertically to 1037', there is no cost-effective means to survey once each 500' as required in regulation 25.050 (C)(1). Unocal will obtain the required surveys at the first opportunity after cementing the 9 5/8" casing, before drilling the 8 %" hole, to eliminate the risk of a well-to-well collision and ensure accuracy of the final BHL. e """", . ...... f': 0 F AI.. t t ~ ~~."'''.''''~ " _.l. ~.., ....~L' -~,., .:,~ I : * ....49 II::I.

Š VJ6k 1. Based on offset drilling & well test data, the pore pressure gradient is predicted to be a si/ft gradient from surface to planned total depth at 11,383' VD BRT. Unocal has drilled two wels to 9700' V n this pad, and has reviewed data from three other deeper wells within a 2.5 mile radius (NNA #1, HV #31-22 & Deep Creek Unit #1). 2. The M.A.S.P. during drilling operations will be governed by the 7" shoe frac gradient, and is calculated based on a full column of gas between the 7" shoe and the surface. The shoes for HV #3 will be at the same depth as the shoes in HV #1, thus the LOT data from HV #1 is useful for relatively accurate kick tolerance & MASP calculations. 3. The MAS.P. during production operations will be the estimated SIBHP minus the gas hydrostatic pressure between TD & the surface. The 7" intermediate casing must be designed to handle a potential burst load case based on a shallow leak in the 31/2" pipe early in the life of a 11,383' VD gas completion (i.e. before reservoir pressure declines).

Prior to drilling out the shoe track, a casing test will be performed at a constant rate. Plot drill pipe pressure and casing pressure versus barrels pumped using the latest Unocal FIT/LOT program. Note: It is recommended to do this test at the same rate at which the LOT will be performed, if practical. This test can be useful as a baseline for the LOT to determine the volume required. 2. Drill out shoe track, clean out rat hole, and make 10' of new hole. 3. Circulate bottoms up and note bottoms up formation. 4. Have a consistent mud weight in the drill string, annulus, choke line and kill line. 5. Pull bit inside casing shoe. 6. Install gauges, preferably calibrated, on standpipe and choke manifold. Note: Pressure rating on the gauges should be of an acceptable range for the anticipated pressure required. Recorders should be used if available. 7. Rig up and pressure test lines to a low and high pressure. 8. Shut-in BOP on drill pipe. 9. Break circulation through choke manifold. Close choke. 10. Pump mud down the drill pipe at constant rate (~ - 1 bpm). 11. Record the drill pipe pressure and annulus pressure at a constant volume increment as established above. Note: Also record the subsea stack gauge(s) pressure(s), if applicable 12. Stop pumping after having gathered 4 data points at injection pressure. See example of injection pressure in Attachment IV 13. Record the 10 second shut-in pressures, and pressures every one minute for three minutes. Page 5 of 12 UNOCAL Drilling Worldwide tit SOP: Formation Integrity Test &~ak-Off Test Procedure Revised: 09/04/03 by DriUing Superintendent Network 14. Bleed off annulus pressure, record the volume bled back, and open BOP. Note: Only bleed pressure off on the annulus side, especially if using motors and LWD tools. 15. Plot drill pipe pressure and casing pressure versus barrels pumped using the latest Unocal FIT/LOT program. The pressure to be used for calculating the LOT is the 10 second shut-in pressure on the casing gauge. Note: Also record the subsea stack gauge pressures, if applicable. 16. Report LOT results as per the reporting section in the SOP. NOTE: Deviations from this LOT procedure will be subject to Management of Change documentation. Page 6 of 12 It tit Cement Volume Calculation Happy Valley Well #3 Kenai Peninsula, Alaska Assumptions: 1. The 9 5/8" surface casing must be cemented to surface, to provide maximum; (a.) structural stability, (b.) long term well control security, and (c.) protection of fresh water sands. Based on experience with HV #1 & #2, the volume calculation below assumes 50% excess slurry will be required ensure cement returns to surface. 2. The 7" intermediate casing cement volume will be based on a cement top at +/-1600' MD, which is designed to be approximately 563' below the planned 9 5/8" shoe. Based on experience, the calculation below assumes 30% excess cement is required. 3. Assuming a gas discovery is made, the 31/2" primary cement volume will be calculated based on a cement top approximately 500 to 1000' above the highest commercial gas sand, or at the 7" shoe, whichever is lower. The following calculation assumes a cement top at 4100' MD, with 20% excess volume. However, the actual cement volume will be determined based on an analysis of the open hole logs. 9 5/8" Suñace Casing: Open hole volume = Conductor Volume = Shoe Track Volume = Total slurry volume = Lead Slurry Volume = 11.43 + (((12.25)^2-(9.625}^2)*3.1417/4/144/5.61*637*1.5) = Tail Slurry Volume = 3.04 + (((12.25)^2-(9.625)^2}*3.1417/4/144/5.61.JD9.1* *1.5) = Lead Slurry: Class 'H' w/ 3% gel at 12.8 ppg yield: . ~.

Emergency slips for 31/2" tubing and 7" intermediate casing will be on location in case either string sticks with the hanger not landed, Le. while reciprocating or while running in the hole. 2. If returns are lost during the 9 5/8" surface casing cement job, or if cement is not circulated to surface, it will be necessary to perform a top up job inside the 9 5/8" x 13 3/8" annulus. This would be necessary to obtain a competent pressure seal below the 13 3/8" starter head and to ensure mechanical stability at surface (Le. for future HWOU operations, etc.). 3. No contingency is required in the event returns are lost during the 7" intermediate casing cement job, provided an adequate shoe exists to drill ahead. If the 7" shoe leak-off test yields unacceptable results, and if / this is determined to be due to lost returns while cementing, the 7" shoe can be squeezed and re-tested. 4. Lost returns during the 3 1/2" primary cement job potentially could lead to a loss of reserves, but will not result in a safety problem due to the depth of the 7" shoe and the presence of the 31/2" x 7" packer positioned approximately 100' above the 7" shoe. Should it become necessary, coil tubing could be utilized to block squeeze any potentially productive intervals not covered by the primary cement. Note: Should the 3 1/2" x 7" annulus fail to pressure test, after the cement has had time to setup, it is proposed that the situation should be discussed with the AOGCC and a mutually agreeable course of action woould be determined prior to perforating for production or for testing. The proposed minimum test pressure would be 500 psi above the 7" shoe leak-off test pressure, adjusted for differences in fluid density. 1<" 22' 6" or 270" .... 16" Cut 72· below grade 11" 5M MBS ./ Wellhead <--. 9 5/S" Hanger Starter Head Top Up Ports --------------------------------- 2" thick base Dlate 12" S'O" Note: Top of Lower Master Valve (or temporary cap) must be <2' AGL to skid derrick. .... 75" 17' or 204" 2' Skid Base 1 (M"'6. 38" S' or 96'· 25" 24' 12" t Automatic Choke 3" 5,000 PSI Choke I\t'I3nifold Kuukpik Drilling 5 e e Happy Valley Cuttings Disposal Description for Permit to Drill The drilling muds and cuttings from the Happy Valley #3,4,5, and 6 Well will be ground and injected into the NNA #1 annulus, into the perforations in the tubing in accordance with an AOGCC approved test plan for the perforations in the tubing, or into the tubing and perforations of the NNA #1 Well should that well achieve permitted Class II injection status during the Happy Valley drilling operations. Permission for the annular disposal has already been secured from the Alaska Oil and Gas Conservation / Commission (AOGCC) and is being currently sought for the tubing-related disposal options. The cuttings will be transported to the NNA # 1 pad with the grinding to occur at the NNA #1 pad. Unocal Alaska does not intend at this time to request authorization under 20 AAC 25.080 for an annular disposal operation in the Happy Valley #3, 4, 5, or 6 well. In the event that a problem develops such that Unocal is unable to inject drilling waste into the NNA # 1 well the possibility exists that Unocal may then request authorization for annular disposal into one or more of the other Happy Valley Wells.

Lower Beluga Formation sands were secondary objectives. Both formations are successive continuous units of the greater Tertiary Kenai Group. Epoch Well Services provided RIGWA TCH 2000TN Drilling Monitoring and DML TN Mudlogging Services. A QGMTM (Texaco patent) Quantitative Gas Measurement gas trap was positioned at the shale shakers for optimum agitation, mud gas was continuously extracted by vacuum pump, and the gas retums were detected, measured and analyzed by EPOCH Total Gas Analyzer and Gas Chromatograph using (FID) Hydrogen Flame Ionization method. The gas system was regularly cleaned, tested and calibrated. Cuttings samples were collected at regular 30' intervals as directed by Unocal's sampling program. 5' and 10' samples were collected in any potentially significant zone, and especially in all sand and gas shows below the T70 coal marker. HAPPY VALLEY #3 Unocal Alaska Resources, Inc. spudded the Happy Valley #3 well on Feb. 03, 2004 with Kuukpik Rig #5. Drilling progressed poorly with rig delays at 154' while trying to drill with casing. Penetration rates decreased to 1 minute per foot, the casing was pulled and a conventional bit and BHA used. A total depth of 1030', was reached on 02/05/04. The rig was skidded seven feet and Happy Valley #4 was spudded on Feb. 06, 2004. Drilling resumed on the #3 well on 2/22/04, and drilling to 4278' progressed without delay. The estimated top of the Tyonek formation, based on samples, is 6340'. The first Tyonek gas show was in medium to very fine lower, ash and silt matrix and grain supported sands from 6370' to 6410'. Before/during/after gas readings were 40/227/40 units. Fair visible porosity. There was a gas show was from 6812' to 6853' in very fine upper to fine lower sandstone locally grading to medium lower. There were some white angular coarse grains at 6820'. Before/during/after gas readings were 12/205/45 units. Swab gas was noted while drilling this zone. Ashy clay matrix-supported sandstone dominant to 6820', and grain supported sandstone dominant below 6820'. Poor to fair clay fill porosity to 6820' and fair porosity below 6820'. The T10 top was 6885', with gas show to 6905'. Cuttings were mostly disaggregated coarse to fine grain- supported sandstone. Before/during/after gas readings were 30/205/40 units. The T17 top was 7235', with gas show to 7250'. Cuttings were medium to fine lower poorly sorted sands with moderate to moderately well developed sphericity. The initial slightly ashy matrix increased to moderately ashy by 7280'. Grain supported at the top and transitioning to mixed grain and matrix supported by 7250'. Some sandstone graded to an ashy tuffaceous siltstone. Poor to fair porosity and permeability determinations were dependent on the matrix volume of ash and silt. The T40 top was 8145', with gas shows to 8175' in very fine lower to fine upper hydrophilic clay matrix- supported sand and sandstone. Before/during/after gas readings were 80/205/40 units. Recorded before/during/after rate of penetration readings were 100/180/40 ftIhr. Poor to locally fair ash and clay fill porosity. 5 units of connection gas recorded in this interval. [:I EPOCH 5 · · · UNOCALIÞ Happy Valley # 3 The top of the T70 marker was at 9037'. The marker was an 18' grayish black to black coal section with thin laminar carbonaceous shale at partings, locally abundant disseminated micro-pyrite and visible bleeding gas. The T80 top was at 9157', with a slight gas show to 9195' in (minor) very fine lower to (common to abundant) medium sandstone that has basal grains ranging to coarse upper as it becomes locally conglomeratic. The sandstone is dominantly matrix supported plus some very localized grain support, with mostly fair visible porosity and clay-influenced variable estimated permeabilities. Before/during/after gas readings were 18/80/15 units. Recorded before/during/after rate of penetration readings were 40/180/20 ftlhr. The drill bit was beginning to lose its outside cutters; resulting in a slowing of penetration rates until the eventual bit trip at 10575'. Slower ROP rates resulted in lower gas readings. The initial recordings of ethane (C2) gas was at the top of the T80 sand. The T90 top was at 9437', and indicated by the intial noted the intial recordings of propane (C3) gas. The lithology was thinly-bedded sands with very little gas. The T130 top was at 9950', with faint gas shows to 9995' in very fine upper to very coarse upper very poorly sorted sand and conglomeratic sand. Sand initially appeared sub-rounded to rounded with moderately well developed sphericity transitioning to moderately developed by 9985'. Initial abundant silt and ash matrix supported sandstone with poor to fair porosity, becomes mixed matrix and grain supported with fair porosity by 9980'. Before/during/after gas readings were 8/25/15 units, and before/during/after rate of penetration was 20nO/35 ftlhr. Butane (C4) gas was recorded throughout the T130 zone, with a maximum reading of 80 ppm and consistent (bleed-off?) of 0-20 ppm after 10250'. The T140 top was at 10155', with gas shows to 10177' in very fine lower to coarse upper poorly sorted conglomeratic sand, dominantly sub-rounded with moderate sphericity, and lightly to moderately ash matrix supported. The sand had fair estimated porosity and permeability. Before/during/after gas readings were 12135/18 units, and before/during/after rate of penetration was 17 nO/20 ftlhr. There was a bit trip at 10575'. Trip gas was rising at 940 units when the rig lost power for twenty minutes. Estimated trip gas was 1000 units to 1200 units. Numerous recycles ofthe trip gas and coal gas produced a fluctuating gas background for the next 150'. After the trip, penetration rates increased from 12 ftlhr to 100 ftlhr, and the background gas increased. The T155 top was at 10655'. The interval from 10655' to 10680' was fine lower to medium upper to scattered very coarse to pebble sand and conglomeratic sand. Initial mean grain size was fine, and increased gradually with depth. Most sandstone was grain supported, but the ashier zones were dominantly matrix supported. Estimated porosity was fair to good. Before/during/after gas readings were 170/360/85 units, and before/during/after rate of penetration was 100/140/90 ftlhr. Happy Valley #3 reached a Total Depth of 11344' MD /10772' TVD in the T165. There were significant increases of devitrified ash and tuffaceous siltstone in the T165. g EPOCH 6 .
