Please let me know if any further action iMuired by Aurora to cancel this approved Permit. Thanks, Ed Jones )' X I Ed Jones ~/~ Vice President l / Engineering & Operations / . i Aurora Gas, LLC í' F{ECEfVED JUN 09 Z004 Aiacka Oil 6/9/2004 -- e NOTE TO FILE Aurora Gas, LLC Diverter Waiver Request Kaloa #2 (203-071) Aurora Gas, LLC (Aurora) has applied for an exception to 20 AAC 25.035(c)(1)(B) that requires the diverter line size to be equal to or greater than the drilled hole size. The reason for Aurora's request is that the planned casing/hole size for the surface interval has been reduced. In the new plan, the maximum hole size possible is now 10-5/8", which gives a hole area 13% larger than the 10" diverter line cross-sectional area. It is Aurora's contention that the surface hole on the subject well can be safely drilled. This document considers Aurora's request and recommends approving it. Kaloa #2 is being drilled as a gas well with a planned TD of 3700'. The surface hole will TD at 620'. This well is located -120' from the Albert Kaloa #1 (AK#1) (167-031) which was drilled in 1968 and P&Aed in 1974. The AK#1 did produce gas from intervals near 3600', however sand production was experienced and it was not possible to keep the we II bore clean. According to the AK#1 mud log, surface casing in that well was set at 285' and cemented to surface. The surface hole section and the next hole interval were both "piloted" and sUbsequently opened after logging. The file records do not indicate any problems encountered drilling these intervals. Given the operations performed, the time necessary to drill, log, open and case the hole sections does not indicate many difficulties. Examination of the mud·log indicates that methane was first detected around 500' md which is slightly shallower than the planned surface casing depth. The minimum planned mud weight for this hole section is 9.5 with provisions to increase to 10 ppg if necessary. The rig is equipped with required mud pit monitoring equipment and since the rig will only recently have started up, an AOGCC Inspector will have witnessed the function testing of such equipment either on this well or one prior to it. The requirement to have a diverter line size greater than the initially drilled hole size is to prevent the diverter line from acting like a choke if a divert situation were to occur. With the hole and casing sizes originally proposed, Aurora rightly planned to drill a pilot hole. 12-1/4" hole would have given an area 50% larger than the diverter line. The Commission has previously approved drilling a 12-1/4" hole while using a 12" diverter line (hole area 4% larger than diverter line). For the new hole and casing sizes planned, the maximum difference in area is 13% with the likely difference being 5%. 20 AAC 25.035 (h) (2) allows the Commission to approve a variance from the diverter requirements if [...] the variance provides at least equally effective means of diverting flow away from the drill rig [... J. I recommend approval of Aurora's request based on the file review conducted. T~S appr.oval i.S SpeCifijl~Y for Kaloa #2. ~^v\~~~~L?

Edward Jones Executive Vice-President, Operations and Engineering Aurora Gas, LLC 1400 West Benson Blvd. Suite 410 Anchorage, AK 99503 Request for Waiver of Diverter Requirements at 20 AAC 25.035 (c)(l)(B) Kaloa #2 (PTD 203-071) Dear Mr. Jones: We have received your request for exception to the Diverter requirements at 20 AAC 25.035 (c) (l)(B) for the drilling of Kaloa #2. You have requested this exception due to decrease in the tubular and hole sizes planned for the well. 20 AAC 25.035 (c)(l)(B) requires that the drilled surface hole be equal to or less than the inside diameter of the diverter line. Providing a diverter line larger than the hole size prevents the diverter line from becoming a choke if a divert situation were to occur. As now planned, Aurora will set 11-7/8" conductor which will allow a maximum hole size of 10-5/8" to be drilled. It is planned to drill a 10-114" hole if such bits can be obtained. If the maximum hole size were drilled, the hole area would be 13% larger than the diverter line area. If 10-1/4" hole is drilled, the area difference is 4%. Aurora will be employing the same rig used during the last 2 seasons. The rig is equipped with the required pit monitoring equipment. Since the rig will have recently started up, an AOGCC Inspector will have witnessed the function testing of such equipment either on this well or one prior to it. Aurora's plans a minimum mud weight of 9.5 ppg with provisions to increase to 10 ppg depending on hole conditions. 20 AAC 25.035(h)(2) allows the Commission to approve a variance from the diverter requirements if [. . .] the variance provides at least equally effective means of diverting flow away from the drill rig [. . .]. e e Lone Creek #3 PTD 203-062 April 16, 2004 Page 2 of2 Your request to employ a 10" diverter line while drilling either 10-5/8" or 1 0-1/4" hole for Kaloa #2 is approved.

Aurora has modified its drilling program to reflect the following changes in wellbore geometry. Conductor: Original well design used 13-3/8" 54.5# K-55 welded. Will now use 11- 7/8" 71.8# USS limited service structural pipe with 0.582" wall thickness. The conductor will be driven as originally permitted. Surface Casing: Original well design used 9- 5/8" 36# K-55 LT&C. Will now use 8 5/8" 32# Wildcat 50, ST &C. Hole size will be 10-5/8" (possibly 1 O-W' if available) and original planned hole depth will be the same. Production Casings Original well design used 7" 23# J-55 LT&C. Will now use 5-W' 17# J-55 LT&C. Hole size will be 7-7/8" and original permitted hole depth will be the same. All other aspects of the original approved program will remain the same. Based on the above information, Aurora is submitting a waiver request under separate cover to forgo drilling a pilot hole at surface as required in the original approved PTD.

Dear Mr. Nonnan, Aurora Gas, LLC has submitted under separate cover, a Sundry Application reflecting proposed changes in the wellbore geometry ofKaloa No.2, PTD # 203-071. Based on the change in well design, Aurora at this time requests a waiver to the requirement that a pilot hole be drilled, a requirement indicated in 20 AAC 25.035 (c)(l)(A & B) which states that the diverter outlet and line must be at least 16 inches in diameter or as large or larger than the diameter of the hole being drilled. The basis for the request is indicated below. Aurora will now use 11-7/8",0.582" wall, 71.8# LSS with a drift ID of 10.625" for a conductor. The original PTD was approved using a 13-3/8" conductor. The drilling program now calls for drilling out with a 10-5/8" or smaller ill bit. The diverter that Aurora intends to use has a 10" gate valve and flow line. Aurora intends to use a lO-W' or 10-5/8" bit, depending upon availabilities, to drill the surface hole. (The largest possible surface hole size will be 10-5/8" in diameter, due to constraints induced by the ill of the 11-7/8" conductor). Aurora is confident it can safely drill using the diverter / hole size configuration requested for the following reasons: 1. Aurora feels that due to the minimal difference between wellbore diameter and diverter line size, the surface hole section can be safely drilled without benefit of drilling a pilot hole first as was specified in the original approved PTD. The actual cross sectional flow area difference between OR and diverter line size is ~10 in2 (13% larger) with a 10 5/8" bit and ~4 in2 (5 % larger) using the 10 Y4" bit proposed. 2. Goodpressure infonnation is available in well records from nearby offset wells Albert Kaloa No. 1 and Simpco Kaloa No. 1 to correlate pressure trends. 3. Good understanding by rig and crew of drilling conditions which might be encountered. 10333 Richmond Avenue, Suite 710· Houston, Texas 77042. (713) 977-5799.

In retrospect, the original well-bore design was permitted for a 12-114" surface hole which required the drilling of a pilot hole. The cross-sectional flow area difference between the 12-W' hole and 10" diverter line was ~39.3 in2 (50% larger). .

All major equipment and supplies will be barged across the Cook Inlet from the OSK dock in Nikiski to Tyonek for staging as required. Equipment will be staged from either Tyonek Contractors yard or one of several existing well sites Aurora is currently re-deve10ping. Personnel can be flown into either the nearby Shirleyville airstrip, a three mile drive, or the Tyonek airstrip which is approximately 7.5 miles away. An alternate site for embarkation will be the airstrip at Beluga, approximately 10 miles away. Crews will be billeted at either Shirleyville or Beluga, pending room availability. All sites are interconnected with an extensive road system for transport via vehicle. Rig: Aurora Well Service, Rig No.1 (A WS 1) will be used to drill the Ka10a No.2 well. A WS 1 has been used previously for work on wells in the Nicolai Creek Field. The pits, BOP system and mud equipment configuration will be similar to that used for previous work. Aurora Gas LLC. Rev. 1.4 Page 2 of6 4-April-2003 Aurora Gas, LLC. e KaZoa.. 2 Drilling Program Pressure Considerations: Based on test pressure information from the nearby Pan Am Ka10a No. 1 well, the following were maximum pressures recorded prior to production for fuel gas on the Spark Platform and for the Village of Tyonek. A maximum SIP pressure at surface of 1450 psi and a shut in BHP of 1580 psi were recorded for the production zone from 3516' - 3583'. This equates to a pressure gradient of .44 psi/ft, or mud weight equivalent of 8.46 ppg. This will require well drilling and completion operations to use fluids weighted from 9.0 - 9.2 ppg to maintain well control at final depth. Final surface pressures recorded after production and prior to plugging and abandonment indicated pressures ranging from 1350 - 1400 psi. Survey Program: The Kaloa No.2 well will be drilled as a vertical well. Wellbore surveys will be obtained at 500' intervals in accordance with rules laid out in 20 MC 25.050 (a) (1) & (2). Drilling Fluids: The drilling fluids are being furnished by MI Drilling Fluids. MI has extensive experience with drilling activities in this area. An experienced mud engineer will be on site at all times while drilling to monitor mud rheology and make recommendations. Attached is a copy ofMI's mud program. Drillin!!

Common known hazards are as follows: Shallow gas: Shallow gas is a known hazard which exists throughout the area. The northwest side of Cook Inlet is noteworthy for its shallow gas hazard. All responsible personnel will be made aware and a notice of such hazards will be posted in the rig doghouse. There is no record ofH2S in the region, however; a gas detection system capable of detecting H2S as well as methane will be installed on the rig with detectors at the floor level, the shale shaker and in the cellar . Coal Seams: The Cook Inlet region is rich in coal seams, interbedded between the sands, gravels and shale's that make up the Beluga and Tyonek formations. Drilling into a coal seam will appear to be a drilling break when drilled with a tri- cone bit. The major hazard of drilling into a coal seam without observing the proper response, is the risk of stuck pipe. The proper course of action for preventing stuck pipe is two-fold. First, prior to drilling, insure the drilling fluid system is up to par, per recommendations from the on-site mud engineer. The second step to successfully drilling through coals in the Cook Inlet area is to not get greedy when coals are encountered. When a coal has been encountered, pull back above coal after drilling into it, and circulate, allowing the coal to stabilize. Re-enter, drill some more, and pull back out again. Continue in this fashion until successfully through the coal bed. The key word in successfully drilling the coal beds is patience. It should be remembered that coals behave plastically, and will flow under the weight of the overburden. The deeper the coal, the more pronounced this tendency becomes. For this reason it is critical to maintain the proper weight and viscosity of your drilling fluid to properly remove the coals drilled up, and to hold flowing coals in place. Again, heed the recommended drilling fluid program and advice offered by the Mud Engineer. Nearby Well's: There are (2) wells within ~ mile ofthe proposed Ka10a No.2. These wells are the Pan-Am Kaloa No.1 which is P&A'd, and the Simpco Ka10a No.1, which is suspended. Neither well presents a proximity problem for drilling operations.

Be extra vigilant while performing hole opener - run. ..J There is no H2S risk anticipated for this well. ..J Due to potential for shallow gas kick, very little response time will be afforded to respond. PVT and gas detection systems must be fully operational and functioning at all times, visual flow checks and pit level monitoring are critical.

When Commission staff began reviewing the permits for completeness and compliance with our regulations (20 AAC 25), a number of deficiencies were identified in each permit. Email messages were sent to Mr. Duane Vaagan on April 22 (for operations and engineering) and Mr. Randy Jones on April 18 and April 21 (for land and ownership) listing the deficiencies and requesting their action to complete the PTD applications and allow the Commission to process them in a timely manner. Mr. Vaagan responded on April 30, providing the requested operations and engineering information. The land and ownership information has been slow in arriving. Sufficient information was ultimately received in mid-June to allow Lone Creek #3 (PTD #203-062) to be approved on June 25th and Mobil Moquawkie # 1 (PTD #203-068) to be approved on July 31st. However, several land and ownership items are still outstanding on the remaining applications. Mr. Jones was again contacted by phone on June 24, and an updated listing of the PTD application deficiencies was sent to him by email. A copy of that deficiency list is attached. Mr. Ed Jones October 16, 2003 Page 20f2 . , Despite repeated written and telephone requests for the needed information and documents to complete the PTD applications for Long Lake #1, West Moquawkie #1, and Kaloa #2, these application remain incomplete. This is unacceptable. Be advised, that if the Commission does not receive the necessary information to complete the PTD application packages for the subject wells by November 3,2003, the applications will be cancelled. DATED at Anchorage, Alaska and dated October 16, 2003. ~ ~~ Randy ::idriCh Commissioner By Order of the Commission · , Aurora Gas LLC 2003 Proposed Cook Inlet Basin Projects Permit to Drill Applications - Additional Information / Needs Updated October 16, 2003 Long Lake #1: (Permit to Drill number 203-068) expected spud date was May 20,2003. a. Designation of Operator and Notice of Change of Ownership forms (Forms 10-411 and 10-417, respectively) must be submitted to AOGCC for this lease, which is Mental Health Trust Lease 9300023. These forms are located on AOGCC's website at: http://\vww.aogcc.alaska.gov/forms/formscat.htm. Pertinent regulations are attached to the end of this letter. b. SPACING EXCEPTION REQUIRED: due to close proximity (less than 500') to property line with an Escopeta lease to the south and apparently unleased Mental Health Trust land to the east. Our regulation states: ".. . for a well drilling for gas, a wellbore may be open to test or regular production within 1,500 feet of a property line only if the owner is the same and the landowner is the same on both sides of the line;" (see attached regulations, below). Landowner means "the owner of the subsurface estate of the tract affected," and owner means "the person who has the right to drill into and produce from a pool and to appropriate the oil and gas the person produces from a pool for that person and others." The spacing exception process takes about 6 weeks. Spacing exception application requirements are published in AOGCC's regulation 20 AAC 25.055 (d), which can be found on the Internet at: http://www.aogcc.alaska.gov/Regulations/art199.htm. A spacing exception is not needed to drill a well. but approval to perforate. test. and produce that well is contingent upon the Commission's issuance of a conservation order approving the spacing exception. By drilling a well without a spacing exception. Aurora assumes the 1iabi1itv of any protest to the spacing exception that may occur. West Moquawkie #1: (Permit to Drill number 203-070) expected spud date was June 20,2003. a. Designation of Operator and Notice of Change of Ownership forms have not been filed for this lease, which is C-61389. b. SPACING EXCEPTION REQUIRED: Simpco Moquawkie 1, 1,400' to the Southeast, is classified as a shut-in gas well, and is completed in the same interval as proposed for the West Moquawkie #1 re-comp1etion. Simpco Moquawkie 1 also lies within the same section (Section 36). Alaska Oil and Gas Conservation Commission 1 · , Kaloa #2: Pennit to Drill number 203-071, expected spud date was July 1, 2003. v a.

(a) The commission will, in its discretion, establish drilling units to govern well spacing and prescribe a spacing pattern by pool rules adopted in accordance with 20 AAC 25.520. In the absence of an order by the commission establishing drilling units or prescribing a spacing pattern for a pool, the following statewide spacing requirements apply: (1) for a well drilling for oil, a wellbore may be open to test or regular production within 500 feet of a property line only if the owner is the same and the landowner is the same on both sides ofthe line; (2) for a well drilling for gas, a wellbore may be open to test or regular production within 1,500 feet of a property line only if the owner is the same and the landowner is the same on both sides of the line; (3) if oil has been discovered, the drilling unit for the pool is a governmental quarter section; not more than one well may be drilled to and completed in that pool on any governmental quarter section; a well may not be drilled or completed closer than 1,000 feet to any well drilling to or capable of producing from the same pool; (4) if gas has been discovered, the drilling unit for the pool is a governmental section; not more than one well may be drilled to and completed in that pool on any governmental section; a well may not be drilled or completed closer than 3,000 feet to any well drilling to or capable of producing from the same pool. Alaska Oil and Gas Conservation Commission 2 · , 20 AAC 25.020 DESIGNATION OF OPERATOR If an owner of a property wishes to designate a new operator for the property, the owner shall submit to the commission for approval a Designation of Operator (Form 10-411). The commission will not approve the designation of a new operator without the signature of the newly designated operator on the same Designation of Operator form. By signing the Designation of Operator form, the newly designated operator agrees to accept the obligations of an operator. The newly designated operator shall furnish a bond and, if required, security as provided for in 20 AAC 25.025. The commission's acceptance of the designated operator's bond constitutes the release of the former operator's bonding obligation for the property indicated on the Designation of Operator form. 20 AAC 25.022 NOTICE OF OWNERSHIP Within 15 days after a person becomes an owner of a property on which operations subject to this chapter are proposed to the commission or are being conducted, the person shall file a Notice of Ownership (Form 10-417). ------------------------------------------------------------------------------------------------------------ Alaska Oil and Gas Conservation Commission 3 N,otice of Change of Ownership and Designation of Ope... e e Randy, I received fax copies of the Notice of Change of Ownership and Designation of Operator forms on 7/17/2003. Your inclusion of the well name "Simpco Kaloa No.2" in the legal description on these forms is confusing. Our records show an existing well, Albert Kaloa 1, drilled by Pan American (Amoco) in section 26, T11N, R12W during 1967 - 1968. Our records also show a second, existing well in this same section, Simpco Kaloa 1, that was drilled by Simasko Production Company in 1978. However, our records do not show a well named Simpco Kaloa No. 2. I know Aurora Gas, LLC has submitted a permit to drill application for a proposed well, Kaloa No.2, to be drilled within 20 feet or so of the Albert Kaloa 1. This proposed well is the likely the source of the erroneous Simpco Kaloa NO.2 name on the forms. In any event, it would be best to eliminate the well reference on these forms. Aurora appears to own and desires to operate all of lease C-61393, and I believe that is what you intend the Notice of Change of Ownership and Designation of Operator forms to convey, rather than just ownership and operatorship of a single well. I also note that section 23 is listed in the legal description on the Notice of Ownership but not on the Designation of Operator form. Also, in regard to section 27, Aurora appears to be owner and operator of the onshore (fractional) portion of section 27 only. The current description on your forms implies ownership and operatorship of all of the E1/2 E1/2 E1/2 of section 27, both onshore and offshore. The offshore portion of section 27 is part of state lease ADL 17586. Please check the descriptions on both forms carefully as these are legal documents. The State of Alaska and BLM have an excellent site on the Internet at h~~£://~~.dnr.state.ak.~§jlri~j~~~L~j/ that you can use to access land status plats for Alaska which are presented in Adobe Acrobat format. Leases such as C-61393 are not labeled on the DNR/BLM plats, but these plats can still be used to check legal descriptions. The Commission has also purchased an excellent set of land maps produced by Mapmakers Alaska that I use in conjunction with the DNR/BLM plats. Their website can be found at http://www:mapalaska.com/. The Commission's regulations can be found on the Internet at http://www.state.ak.us/local/akpages/ADMIN/ogc/Regulations/RegIndex.htm.

However, a 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. Long Lake #1: Permit to Drill number 203-068, expected spud date is May 20, 2003. a.

Perforations in Simpco Moquawkie 2 are open in Tyonek Fm. from 5666' - 5708' MD and 5880' - 5945' MD. Perforations in shallower intervals have all reportedly been squeezed. Since the Moquawkie #1 re-comp1etion will be in the Moquawkie SS member between 2735' - 2874' MD (an interval about 2800'shallower) a spacing exception is not required as long as re-comp1etion operations are restricted to 2900' MD and shallower.

ALASKA 99501-3539 PHONE (907) 279-1433 FAX (907) 276-7542 June 18, 2003 Ms. Lydia Miner Section Manager Exploration, Production and Refineries Alaska Department of Environmental Conservation 555 Cordova Street Anchorage, AK 99501 RE: C-Plan Exemption for Planned Aurora Gas, LLC 2003 Activities on the West Side of Cook Inlet Dear Ms. Miner: The Alaska Oil and Gas Conservation Commission ("the Commission") received your request for a formal determination regarding an exemption from Oil Discharge Prevention and Contingency Plan requirements for wells and re- completions planned by Aurora Gas, LLC ("Aurora") on the west side of Cook Inlet during 2003. In order to evaluate Aurora's request for an exemption from the oil spill contingency plan requirements for this program, I have reviewed all of the information submitted by Aurora, and the Commission's well files, log files, production records, and records associated with Conservation Order No. 478 (spacing exception for the drilling and testing of Nicolai Creek Unit wells #1 B, #2 and #9). Recommendation Based on a detailed examination of Commission records, it is unlikely that any of Aurora's proposed re-completions or new wells will encounter oil or oil-bearing formations in their interval of interest, which includes the Beluga Formation and shallow portions of the Tyonek Formation. I recommend approval of the requested exemption from Oil Discharge Prevention and Contingency Plan requirements for Aurora's planned 2003 activities on the west side of Cook Inlet, ·- e e .- including the Mobil Moquawkie #1, Simpco Moquawkie #1, West Moquawkie #1, Simpco Moquawkie #2, Texaco Long Lake Unit #1, Nicolai Creek Unit #7, Nicolai Creek Unit #9, Lone Creek #3, and Kaloa #2 wells, and their associated gas production facility and pipeline. A detailed discussion for each of Aurora's planned activities is presented below. All depths presented are measured depths, unless otherwise noted. Moquawkie Area Wells Exemptions are being sought for re-entry, testing, and production of five existing wells in the Moquawkie area: Mobil Moquawkie #1, Simpco Moquawkie #1, West Moquawkie #1, Simpco Moquawkie #2, and Long Lake Unit #1 to evaluate the economics of gas production. All of these are exploratory wells drilled between 1965 and 1978 in search of oil. The four Moquawkie wells mentioned above are clustered on the same structure within a narrow, north-south trending band that is about 1 mile long and ~-mile wide (see map, below). Long Lake Unit #1 is located on a separate structure approximately 4 miles to the west. ~.R12Wi I . I,i . ¡ --¡;-- I ' I I i i I I i Moq uawkie Field 36 I W. Moquawkie 1 ._ -1 I T 12 N.

Oil indicators were recorded on mud logs from the other two wells, Mobil Moquawkie #1 and West 2 e e Moquawkie #1. All of these wells are vertical through the interval of interest, which includes the Beluga Formation and the upper Tyonek Formation. In Mobil Moquawkie #1, three very poor oil shows are noted on the mud log between 2700' and 2810' (-2330' and -2440' TVD subsea), which is the lowest portion of Aurora's interval of interest in this well. Descriptions associated with these very poor shows indicate the oil is residual, and is not live, producible oil ("very few pieces gave dull fluorescence, faint dull gold cut, residual oil in argillaceous sand"). A drill stem test conducted across the interval containing two of these very poor shows yielded very little water and no oil. Mobil Moquawkie #1 was subsequently completed in this interval and produced 985 million cubic feet of gas with associated water from May of 1967 until February 1970, when the well was shut-in. No evidence of oil production has been found in Commission records for this well. The mud log from West Moquawkie #1 notes three "slight trace" oil shows between 2320' and 2580' (-1821' and -2081' TVD subsea). Mud log descriptions mention some dark brown oil stain or "tar stain" associated with a trace to 40% pale to light yellow sample fluorescence and weak to light yellow cut fluorescence, but there is no mention of white-light hydrocarbon cut or live oil. Sixty-six sidewall cores were recovered from the well, including 42 between 795' and 2520'. Detailed lithologic descriptions or laboratory analytical results are not present in the Commission's well file, but summary records for these sidewall cores clearly state "no shows." The well was not tested (the Completion Report lists the well as "dry"), and it was immediately plugged and abandoned. LonQ Lake Unit #1 This exploratory well was drilled, plugged, and abandoned by Texaco in 1973. Commission records do not show any indication of oil in the Beluga or Tyonek Formations within Long Lake Unit #1. The only indications of oil in the well are very poor shows marked on the mudlog in the Hemlock Formation from 5280' to 5290' (-4721' to -4731' TVD subsea), and in the West Foreland below 6655' (-6088' TVD subsea). The shallowest of these very poor shows occurs approximately 1700' below Aurora's interval of interest. Texaco plugged and abandoned Long Lake Unit #1 without testing. Summary for the MOQuawkie Area Wells The absence of oil in well tests or in regular production, the lack of oil shows in sidewall cores, and the very poor quality of all oil shows noted on mud logs indicate that Mobil Moquawkie #1, Simpco Moquawkie #1, West Moquawkie #1, Simpco Moquawkie #2, and Long Lake Unit #1 are not likely to produce oil from the Beluga or shallow Tyonek Formations. 3 e e Lone Creek #3 Well Lone Creek #3 is a proposed vertical, shallow gas well located to the northeast of, and on the same structure as, the Lone Creek #1 and #2 exploratory wells (see map, below). Lone Creek #1 is located high on the structure, while Lone Creek #2 is structurally lower, on the side of the structure. Both wells are vertical through Aurora's interval of interest.

Lone Creek #1 tested only gas from this interval. Lone Creek #2 was plugged and abandoned without testing. Based on records from these offset wells, Lone Creek #3 is not likely to produce oil or encounter oil-bearing formations. Nicolai Creek Unit #7 and #9 Wells and Nicolai Creek Unit #1, #2 and #9 Facility The Nicolai Creek area wells are all clustered near the western shoreline of Cook Inlet. Aurora plans two shallow gas wells in this area, Nicolai Creek Unit #7 and #9. Aurora is also planning a production facility with associated pipeline to collect and process gas from the existing Nicolai Creek Unit #1 Band #2 wells, and the proposed #9 well. 4 e e . Several exploratory and development wells are located in the vicinity of this project area. Records and logs from Nicolai Creek State #1, #1A, and Nicolai Creek Unit #1 B, #2, and #3 (see map, below) were examined. A time-structure map of the top of the Tyonek Formation in the Nicolai Creek Field is published in the Commission's 2002 Annual Report. This report can be accessed on the Internet at: http://www.state.ak.us/local/akpaaes/ADMIN/oqc/homeoqc.htm. Nicolai Creek State #1 and #1A: Nicolai Creek Unit #1B. #2. and #9 The proposed Nicolai Creek Unit #9 well, and the existing Nicolai Creek State #1, #1 A and Nicolai Creek Unit #1 Band #2 wells all penetrate the Beluga and shallow Tyonek Formations within the same reservoir block. Nicolai Creek State #1 is a 1965 exploratory well drilled, then subsequently plugged and abandoned, by Texaco. This well penetrates the Beluga and Tyonek Formations in one of the deepest portions of the fault block that also contains Nicolai Creek State #1A, Nicolai Creek Unit #1B, #2, and the proposed Nicolai Creek Unit #9 well. The Tyonek gas sands were perforated and tested in Nicolai Creek State #1 between 3420' and 3630' (-3305' to -3505' TVD subsea) and they produced dry, clean gas with no associated oil. 24 I Nicolai Ck U 3 I *' 20 , 21 !

These sands were tested, but according to the well file, showed "no oil accumulations." 5 · · e e · · Nicolai Creek State #1A, the first sidetrack of the #1 well, was drilled up-structure from the original #1 well bore. Commission records for #1 A report the shallowest oil indicator as being "solid hydrocarbon" (tar?) encountered between 5535' to 5550' (-5281' to -5295' TVD subsea) and 5620' to 5640' (-5360' to -5379' TVD subsea), which is over 1,500' below Aurora's interval of interest. Shallow Tyonek gas sands were produced in #1A between 3420' and 3630' (-3305' to -3505' TVD subsea). Commission records indicate this interval produced gas for only three months (December 1968 through February 1969), with no associated oil. The second sidetrack of the #1 well, Nicolai Creek Unit #1 B, was drilled up- structure of the #1 and #1 A wells by Aurora in September of 2002. There are no oil indicators shown on the mud log or mentioned in lithologic descriptions contained in the final well report from the mud-logging contractor. Nicolai Creek Unit #9 is a proposed well intended to produce gas up-structure from the #1 B well in the same fault block. The final well in this fault block, Nicolai Creek Unit #2, was drilled by Texaco as an exploration well in 1966. No oil accumulations were encountered. Texaco tested a gas sand between 3270' and 3315' (-2733' to -2768 TVD subsea), with no mention of any associated oil or water. The well produced 52 million cubic feet of gas from September 1968 through October 1969, with no record of any associated oil production. It was re-entered and tested by Aurora during 2002, and flowed gas and water from shallow Tyonek Formation sands. No associated oil is noted in Aurora's test summary reports. In summary, Nicolai Creek State #1, #1 A, and Nicolai Creek Unit #2 tested the down-dip portions of the reservoir block. Nicolai Creek Unit #1 Band #9 will produce gas from the up-dip portions of this same block. Neither #1, #1A, nor #2 have shown any indications of the presence of oil in the Beluga Formation or in the shallow portion of the Tyonek Formation. All of these wells tested or produced dry gas from shallow Tyonek sands with no indications of associated oil production. Therefore, it is highly unlikely that Nicolai Creek Unit #1 B or the proposed #9 well will produce oil or encounter oil-bearing formations. Nicolai Creek Unit #3 and Proposed Nicolai Creek Unit #7 The existing Nicolai Creek Unit #3 well and the proposed Nicolai Creek Unit #7 well will both penetrate the Beluga and shallow Tyonek Formations within the same reservoir block. Texaco drilled Nicolai Creek Unit #3 in 1967 as a Hemlock oil exploration well. The mud log for this vertical well shows only scattered, very poor oil indicators in the Hemlock Formation between 6600' and 7220' (-6400' and -7020' TVD subsea). Texaco did not test this Hemlock interval. The well was plugged back to 2522', and sands between 2000' and 2380' (-1800' and -2180' TVD subsea) were tested for gas. Reports from the test indicate production was dry gas, with 6 .' e e " no associated oil. Texaco produced 893 million cubic feet of gas from the well between March 1967 and September 1977. Commission records indicate only gas was produced; they do not report any associated oil production. In 2001, Aurora tested Nicolai Creek Unit #3 in five intervals between 1900' and 2380' (-1700' and -2180' TVD subsea). The well produced only gas, with no oil or water. The proposed #7 gas well is situated up-structure of #3 within the same fault block. Because the #3 well has shown no indications of the presence of oil in the Beluga Formation or the shallow Tyonek Formation, the proposed #7 well is not likely to produce oil or encounter oil-bearing formations. Summary for the Proposed Nicolai Creek Activities The absence of oil in test or regular production and the lack of significant oil shows in the shallow geologic section in Nicolai Creek State #1 and #1 A, Nicolai Creek Unit #1 B, #2, and #3 all indicate that the #1 B and the proposed #7 and #9 gas wells are not likely to encounter oil in, or produce oil from, the Beluga Formation or shallow portions of the Tyonek Formation. Production facilities associated with Nicolai Creek Unit #1 B, #2 and #9 also have little possibility of receiving oil from any of these wells. Kaloa #2 The proposed Kaloa #2 shallow gas well will be drilled approximately 20 feet from the existing Albert Kaloa #1 well, an oil exploration well drilled in 1967 by Pan American and completed in 1968. 16 15 14 13 Albert Kaloa Field 24 28 Albe Kaloa 1 'f).: Kaloa 2 (proposed) 27 pco Kaloa 1"'- T 11 N, R 12 W Kaloa Area Basemap 7 .' ) I· e e .t In 1970, Pan American perforated Albert Kaloa #1 between 3213' and 3403' (-2982' to -3172' TVD subsea) and flow-tested the well for a total of 29 hours. This test produced 13.4 million cubic feet of gas with "no significant liquid production during test." Gas samples from this test were dominantly methane, with only trace amounts of ethane, propane, and butane. According to Commission records, Albert Kaloa #1 produced 118 million cubic feet of gas from this interval during December 1970 and January 1971, with no recorded oil production. The well bore became plugged with "mud and sand," and was subsequently plugged and abandoned in 1974. The mud log from Albert Kaloa #1 reports 20% dull fluorescence with a slight solvent cut and residue at 3425' (-3194' TVO subsea), but the occurrence was not classified by the mud logging geologist as an oil show. The associated lithologic description does not mention any oil staining or the presence of live oil. Gas associated with this dull fluorescence consists only of methane. The next oil indicator noted on the mud log is a very poor show at 5875' (-5644' TVD subsea). The absence of oil in test or regular production and the lack of significant oil shows in the shallow geologic of the adjacent Albert Kaloa #1 well indicate that the proposed Kaloa #2 gas well is not likely to produce oil or encounter oil- bearing formations. Summary None of the well or production records examined suggest the possibility that oil will be encountered in, or produced from, any of the intervals that Aurora will drill, test, or produce in their proposed 2003 activities. An exemption from oil spill contingency plan requirements is appropriate for Aurora's proposed 2003 activities on the west side of Cook Inlet. Please contact me if you need additional information.

Pre-Application Stage Kuparuk River Rehabilitation Plan: ConocoPhillips Alaska, Inc. proposes to restore the East and West Channels of the Kuparuk: River to their approximate condition prior the spine road development. Contact: Kaye Laughlin. Aurora Gas LLC Projects: Aurora Gas proposes to conduct exploration for gas on a number of sites and a development project at one site during the summer of2003. All ofthese projects are located onshore on the west of Cook Inlet. Exploration activities for five projects will be conducted from existing pads, and no permits are expected to trigger an ACMP consistency review (Long Lake No.1, Mobil Moquawkie No.1, Simpco Moquakie No.1, West Moquawkie No.1, and Simpco Moquawkie No.2). Three exploration projects would likely need an ACMP review (Nicolai Creek Unit No.7, Lone Creek No.3, and Ka10a No.2). A production facility including installation of a four-inch pipeline is proposed near the Shirleyville runway. OPMP sponsored a pre-application meeting on Apri117, 2003. Contact: Glenn Gray. Petro Star Valdez Pipelines: Petro Star, Inc. proposes to construct two parallel petroleum pipelines and a fuel transfer dock on the south shore of Port Valdez just east of the Solomon Gulch Hatchery. In 1992, Petro Star investigated seven different alternative locations for delivering product to a marine terminal. The proposed pipelines will start at the Petro Star Valdez Refinery and continue west, buried under a mile-long section of a new bike path along Dayville road. From Dayville Road, a trestle will extend about 1,000-feet northward to a fuel transfer dock. Petro Star plans construction ofthe buried pipeline to be concurrent with construction of the pedestrian path along Dayville Road Contact: Kaye Laughlin. Borealis Power Project: BPXA proposes to expand infrastructure to meet power demands of future satellite expansion in the western end of the Prudhoe Bay Unit and a possible tie-in with the Milne Point Unit power grid. The project would include a new 69 kV power line, a sub- station, and possible minor pad extensions. The power line would run from the Central Power Station to the L and V Pads in the end ofthe unit and possibly extended to Milne Point. Originally planed for the 2003-2004 winter season, BP notified OPMP that the project has been deferred for another year. OPMP held a pre-application meeting on Apri19. Contact: Kaye Laughlin. DEC Inactive Reserve Pit Closure Program: OPMP is working with state resource agencies and the U. S. Army Corps of Engineers on reserve pit closures required by the DEC solid waste program. Companies are required to complete environmental assessments for all abandoned drilling waste reserve pits and must conduct corrective actions to clean up or prevent release of contaminants at these sites.

I am frankly surprised that Fairweather/Aurora had not sent any paperwork after the meeting. That's what I would have done. Got to keep the ball rolling or in play and not sit on it. I do know that some of the "rush" has changed due to Aurora "re-Iooking" at seismic information. Regardless, the need for "rush" has a way reappearing to bite someone when they least expect it, so again I am surprised that you didn't get any paperwork. Thanks for chasing this, I do appreciate your efforts on our behalf.

Although the Office of Project Management and Permitting has not received a Coastal Project Questionnaire for any of the projects, it appears that some of the projects will not need an ACMP review. Unless there is an permit trigger (e.g., a Corps 404 permit or a state permit included on the "C List"), the following projects will not need an ACMP review: Long Lake No. 1 Mobil Moquawkie No. 1 Simpco Moquawki No. 1 Simpco Moquawki No. 2 West Moquawkie No. 1 For several other wells, an ACMP may be required, and a final decision will be made after Fairweather provides more information to me about the permits needed for the projects: Nicolai Creek Unit No. 7 (ACMP review likely needed) Lone Creek No. 3 (may need a review) Kaloa No. 2 (may need a review) Shirleyville Production Facility (may need an ACMP review) As I recall, Fairweather was working with the Corps to complete wetlands determinations to see if 404 permits are needed and with the Office of Habitat Management and Permitting to see if fish habitat permits are needed. By copy of this email, I will check with Fairweather to see if they have any new information.

After setting the 9-5/8" surface casing, it is a FIT but no value is given. What do you expect?? plans, a EMW value was stated. specified to do In the other 2. I note this BOP drawing does not include the rotating head. 3. In the 7" casing running instruction, it appears to state that the 7" might not be run to TD. If it were determined to not run the casing to TD, we would need to be notified and provisions for isolating any open hole below the shoe would have to be determined. This is similar to questions on the other wells on how to avoid "flip-flop". 4. The XS cement volumes specified are only 15%. Will that be sufficient?? What XS factors did you employ last year?? You may not have surface hole values since I don't think Aurora drilled a grass roots well last year, but the other hole sections might apply. Thanks for you attention to these questions. Tom Maunder, PE AOGCC Response: Kaloa No. 2 1) Sorry about that, we will attempt to test to an EMW of 17 ppg. 2) Since this will be a grass-roots well, we will use a standard circulating system, i.e. pump down drill-pipe with returns up annulus. Because of the area, we don't want to risk plugging our bit or pipe with the coal, gravel and rocks we will be drilling through. 3) We will run the 7" casing to bottom (-3745 - 3750'). This will give us the rat-hole we need inside as well as take care of the cement swap problem indicated. e e 4) As you pointed out, the excess cement amounts for cementing the casing strings indicated in the permit application are insufficient. Further review of historical well records for offset wells Albert Kaloa No. 1 and the Simpco Kaloa No. 1 wells, and the cement volumes that were used when cementing these wells indicate a larger volume should be planned for. We will plan on pumping 100% excess for the 9 5/8" surface casing with the intent to cease displacement operations when good cement is observed at surface. On the Albert Kaloa No. 1 well, 18% excess was required to cement 20" casing inside a 26" hole to surface with returns to surface. When cementing the 13 3/8" casing at 2922', 77% excess cement was used with no mention of any cement being seen at surface. The wells mentioned were cemented using a 15.8 ppg ~G" slurry. In the permit application we initially indicated we intended to use a 15.8 ppg cement system at surface. We are now analyzing a lighter system to cement the surface casing string, the idea being to minimize the potential of losing circulation and maximizing the potential of seeing good returns at surface thereby insuring a good cement job on the surface casing. This is not only critical but a requirement. We will notify and update AOGCC when we have optimized this and describe our intended cement system.

Aurora Gas, LLC 4/23/2003 2003 Mudlogging Program.xls Kaloa #2 ~ Subject: Kaloa #2 Date: Tue, 22 Apr 2003 11 :48:14 -0800 From: Tom Maunder <tom_maunder@admin.state.ak.us> To: Duane Vaagen <duane@fairweather.com> Hi Duane, Here is the note regarding my questions on the Kaloa #2. 1. After setting the 9-5/8" surface casing, it is specified to do a FIT but no value is given. What do you expect?? In the other plans, a EMW value was stated. 2. I note this BOP drawing does not include the rotating head. 3. In the 7" casing running instruction, it appears to state that the 7" might not be run to TO. If it were determined to not run the casing to TO, we would need to be notified and provisions for isolating any open hole below the shoe would have to be determined. This is similar to questions on the other wells on how to avoid "flip-flop". 4. The XS cement volumes specified are only 15%. Will that be sufficient?? What XS factors did you employ last year?? You may not have surface hole values since I don't think Aurora drilled a grass roots well last year, but the other hole sections might apply. Thanks for you attention to these questions.

Long Lake #1: Permit to Drill number 203-068, expected spud date is May 20, 2003. a. SPACING EXCEPTION REQUIRED: due to close proximity (less than 500') to property line with an Escopeta lease to the south and apparently unleased Mental Health Trust land to the east. Our regulation states: ".. . for a well drilling for gas, a wellbore may be open to test or regular production within 1,500 feet of a property line only if the owner is the same and the landowner is the same on both sides of the line;" (see attached regulations, below). Landowner means "the owner of the subsurface estate of the tract affected," and owner means "the person who has the right to drill into and produce from a pool and to appropriate the oil and gas the person produces ITom a pool for that person and others." The spacing exception process takes about 6 weeks. Spacing exception application requirements are published in AOGCC's regulation 20 AAC 25.055 (d), which can be found on the Internet at: http://www.state.ak.us/local/akpages/ADMIN/ogc/art199.htm. b.

Moquawkie #1 is 2500' away from, and in same section as, Simpco Moquawkie 2 (178-088), a shut-in gas well capable of production. Perforations in Simpco Moquawkie 2 are open in Tyonek Fm. from 5666' - 5708' MD and 5880' - 5945' MD. Perforations in shallower intervals have all reportedly been squeezed. Since the Moquawkie #1 re-comp1etion will be in the Moquawkie SS member between 2735' - 2874' MD (an interval about 2800'shallower) a spacing exception is not required as long as re-comp1etion operations are restricted to 2900' MD and shallower.

I'll respond in the order of the questions below. 1. Yes, we have a formal meeting tomorrow afternoon with DGC, ADF&G, COE, DNR and TLO to discuss this and other wells in Aurora's program. In regards to Lone Creek No.3, we are hoping they give the green light to proceed as the only disturbance will be pad construction. No wetlands are being crossed and access will be via road constructed to drill the Chuit State wells years ago. Based on the meeting tomorrow, we will obtain all permits necessary. One thing we do know we need is a survey for a wetlands determination, site suitability and for archaeological or cultural resources. Another permit application submitted is for the Kaloa No.2. I am not so sure we w· this as we need a bridge. By the time we get thr Corp of Engineers and A . will not happen. ._--~ . Waste will be handled as last year, and the following is apPlicablC\ for the entire multi-well program this summer. Brines and muds will be recycled and used to the fullest extent possible. Drilling and workover wastes not recyclable will be transported offsite for treatment and disposal by Enviro-Tech. My apologies for not including this information in the permit application. I realized after I submitted the paper work that I omitted this information on all the wells. I will be submitting a Sundry application for testing and workover of the Simpco Moquawkie No.2 well soon. Base on log analysis and review of historical test results, I will be putting together a permit application for conversion of the SM No.2 well to disposal. This is one of the back-burner wells, but I think we will find that we really need a disposal well. .--._-,","'~----""~'_.--"---- '.

I am not sure what other permitting requirements are out there or how they are now handled, but could you elaborate on what other permits are being sought. 2--How will the drilling waste be handled?? I am aware that Aurora has submitted a request to enter one of the Moquawkie wells with the potential to complete it as a class II well and Aurora has a disposal injection order for Nicolai Crk #5. Are there any plans to do the work on Nicolai Crk #5?? The AOGCC only has authority for annular disposal and class II injection. If other methods are being planned, permits for DEC and/or DNR and maybe others will be necessary. 3--What is the yield on the lead slurry for the 7" cement job?? 4--Could you or Aurora please provide a schedule of the coming planned work with approximate operation dates??
