The well was drilled vertically and achieved a total, depth of 8,578' MD (8,578' TVD) on March 5, 1972. During the course of drilling, an intermediate casing string was run and cemented, and the well was drilled to TD, with no production string set. After reaching TD, sidewall cores were obtained and analyzed, wireline logs were run and the well was declared a dry hole. The decision was made to plug and abandon the well. On March 7, 1972,~following AOGCC guidelines, a series of 6 cement plugs were placed at various intervals in the wellbore to isolate different geologic zones, seal the casing shoe interval, and plug the top of the casing prior to removing the wellhead and installing a permanent "dry hole" marker. On July 15, 1988 Unocal and Marathon Oil Company acquired the NiColai Creek Unit from Texaco Inc. and Mobil Oil Company. Due to poor operating economics at the time, the decision was made to plug and suspend all remaining wells in thbNi661~i Creek Unit until such time that the economics of producing them improved. Aurora Gas, LLC became operator.of the Unit in the year 2000, and has since re-entered, worked over and brought NCU #3 on line as a commercial gas producer. Before other wells in the unit can be developed commercially, it has become evident that an injection well will be required to dispose of Class II non-hazardous oilfield waste, namely produced water, well workover fluids and drilling wastes. NCU #5 has been selected to be re-entered and developed as a Class II disposal well because of its strategic location, vertical well design, favorable cementing records, underlying geology and the economically viable solution it provides. All depths referenced in this application are original RKB, which was approximately 89' AMSL. Surface Grade level is 75' AMSL. A 30" diameter structural conductor pipe was driven to a depth of 34'. A 20" hole was then drilled to 308' and a 16" conductor was set and cemented into place with 600 sacks of Class "G" cement. A 9 7/8" bit was then used to drill out to 2691', a 15" hole opener was run and 10 %", 40.5# J-55 casing was run, set and cemented in place at 2628' with 1440 sacks of Class "G" cement. Reports indicate good cement retums were observed at surface during the cementing procedure. A 9 7/8" bit was run and the well was drilled to TD at 8578'. Wireline logs were run and 32 sidewall cores samples were obtained from 3068 - 8150'. Lack of any commercial oil or gas indicators caused Texaco to make the decision to plug and abandon NCU #5. Class "G" cement plugs were then placed over the following intervals: 7215' - 7000' MD 95 Sacks Fairweather E & P Services, Inc.

Initiate repairs to NCU #5 well site as necessary to mobilize in and spot equipment needed for well re-entry and work-over. . Remove abandonment marker, inspect wellhead base flange if in place. If it has been removed, dress surface casing stub and install a new wellhead. 3~ Mobilize rig, RU, install and test BOP stack, drill out the cement plug at surface. . Verify the integrity of the 10 ~" inch casing through pressure testing and squeezing as necessary. Run cement evaluation log(s). o Perforate the 10 3A" inch casing at desired intervals for waste disposal, perform injection testing as required. o Re-complete the well as a Class II Non-hazardous Oil-field waste injection well. . Remove rig and well work-over equipment, clean well site, install surface injection support equipment and prep for injection. The above work will be performed in compliance with the regulations contained in Alaska Oil and Gas Conservation Commission Alaska Administrative Code: Title 20 Chapter 25. 3.0 Proposed Operations Program The following Operations Program addresses the work scope to be performed in the course of reentry and re-completing Nicolai Creek No. 5 only. The construction of Fairweather E & P Services, Inc. Nicolai Creek Unit No. 5 Rev. 2 Page 2 of 8 4/19/2002 surface injection facilities and eventual connection of Nicolai Creek No 5 to field gathering lines will be carded out at a later date. lo Obtain all required permits and regulatory approvals before starting job.

Notify AOGCC of intent to begin operations. Excavate to install new well cellar as needed and gain access to top of 10 %" casing stub. Remove well abandonment marker. If base flange is present, inspect, clean up as necessary. If base flange in no longer present, trim up casing stub and install new casing head flange. Move in rig and rig up. Hook up tanks, pumps, BOP stack, flOw lines and gas detection and pit monitoring systems as per 20 AAC 25.033 and 20 AAC 25.066. Give AOGCC 24 hour notice of pending BOP test so that they may witness same. Mix 100 bbl, 9 - 9.5 ppg mud to be used for drilling out the surface cement plug in Nicolai Creek No. 5. Pressure test BOP stack, choke manifold and all surface equipment per AOGCC requirements. Pick up 9 7/8" bit and drill out surface cement plug in 10 ~A" casing while maintaining constant watch on fluid volumes. When cement has been drilled out, shut down pumps and monitor well for flow. The well should be dead, but should still be treated as if potential pressures could exist in well-bore below cement plug. Be prepared to shut well in immediately should any flow be noticed. When satisfied well is dead, RIH with bit to PBTD while circulating to top of cement plug at 2500' MD (While tripping in hole, be cognizant of the possibility that junk could have been thrown down wellbore when the well was abandoned in 1972). Tag TOC plug but do not attempt to drill. Notify AOGCC 24 hours in advance of pending casing pressure integrity test so that they may witness same. Close pipe rams at surface and pressure test 10 3/4" casing to 1500 psi. Record results. If test is satisfactory, proceed to step 13. If unsatisfactory, proceed to step 12. Fairweather E & P Services, Inc. Nicolai Creek Unit No. 5 Rev. 2 Page 4 of 8 4/19/2002 12o POOH with bit, PU and RIH with casing scraper to PBTD at 2500' MD. POOH, LD casing scraper and PU retrievable packer, TIH, stopping at 500 ft intervals to pressure test, isolate and repair leak using cement squeeze method as necessary (cementing procedure to be provided). If squeeze job is performed, drill out and retest casing to 1500 psi. Repeat as necessary to produce satisfactory pressure test. If during the course of this and subsequent testing, the casing in NCU #5 is deemed to be mechanically unsound and unsalvageable for use as an injector, the well will be shut in until such time that a new plan can be formulated. 13. When casing has been pressure tested satisfactorily, POOH and PU casing scraper, RIH to PBTD and circulate out mud with 3% KC1 or inhibited lease produced water solution and high-vis sweeps as necessary. POOH, RU wireline with lubricator and RIH with USIT cement evaluation logging tool on wireline. Prior to beginning logging operations, close wireline pack-off on wireline and pressure up wellbore to 1000 psi. Log entire 10 3A" casing string, POOH and RD. If results of USIT are satisfactory, proceed to step 17. If USIT indicates poor cement quality in annulus behind 10 ~A" casing, proceed to step 14. 14o ' If USIT indicates poor cement quality behind 10 %" casing within 500 feet of injection zone, RU wireline with 4" perforating gun, RIH to questionable area, perforate with 4 shots at 4 spf (90 deg. phasing). POOH with wireline. *PU retrievable packer with bypass valve or cement retainer and TIH to just above perforated interval, set packer and initiate squeeze by establishing an injection rate with water.

A hydraulic program will be designed to maintain ~an annular velocity between 85 and 100 in both the 15" and 9-7/8" holes. An annular velocity of approxi- mately 85 is considered optimum through coal beds in order to minimize hole washing and sloughing. · 2.
