The well has only flowed back produced water. At the end of the build-up we request to perform a short duration injectivity test into the open perforations, with the produced water in the test string. This is necessary to evaluate the potential use of this well for water flood. The water produced out of the formation has been between 21,000 ppm and 22,500 ppm chlorides. The requested procedure is outlined below.

Drilling progressed well with no rig delays to 15161' MD / 10018' TVD. Drill pipe became stuck during a trip out of the hole at 10781'. Work and jar on fish for two days and well was cemented back to the shoe (10517'). RU#4 ST was commenced under the shoe and drilled to a depth of 12986' MD / 8516' TVD and became stuck during a trip in the hole at 11980'. Work and jar on the pipe for two days and the well was cemented back to 11371' and RU#4ST#2 was commenced. Drill commenced on 12/27/01 and reached 19047' on 2/10/02 for a casing point. Hole was sloughing and tight. The drill string became stuck while pulling out of the hole at 18450'. The mud weight was dropped from 11.2 ppg to 10.2 ppg. The "differentially stuck" pipe was worked free and back reamed out of the hole (slowly) while pumping weighted sweeps. Numerous "clean out" runs and weighted mud sweeps were made to insure proper hole cleaning and dynamics. Casing was run on 2/24-2/25/0 to 10500', Rig repair prevented further running of the liner and the casing string was pulled from the hole and a clean out run was made. Hole was tight at 18400' to 18900'. Casing was run on 3/2-3/3/02 and reached a depth of 18516', in which a bridge was encountered. Jarring down on the bridge provided no advancement and the casing shoe was set at 18516'. The primary objectives of this Redoubt Unit well were the conglomeratic sands of the Hemlock formation of the Tertiary Kenai Group, on the eastern boundary of the north fault block previously discovered by the No.1 well. The Hemlock was encountered at 18875' (E-Iog depth). Only minor gas increases were observed over the Hemlock because of high mud weight (9.8ppg). No C-4's or C-5's were observed on the chromatograph through the entire interval of the Hemlock. After drilling the top of the West Foreland at 19850'(E-log depth), the well reached a total depth of 20200' on 03/22/02. Epoch Well Services provided RIGWA TCH 2000TM Drilling Monitoring services and DML TM Mudlogging Service. Hydrogen flame ionization (FID) Total Gas and (FID) Gas Chromatograph detectors were employed to detect and analyze formation gases. Constant mud gas was generated by Texaco's patented Quantitative Gas Measurement (QGMTM) electrically driven gas trap located at the shale shaker header box and extracted continuously from the trap to the unit by sample pumps. The gas trap was frequently cleaned and positioned to obtain optimum sampling, and the gas system was tested and calibrated on a regular basis. Cuttings samples were collected at regular 30' intervals, beginning at 7400', as directed by Forest Oil's sampling program. ~ 3?OC:: 4 ; --""] ~ ,.~":: Forest Oil Corporation Redoubt Unit #4 DAILY ACTIVITY SUMMARY 10/28/0 I Insta]] the beaver slide and the stairs to the rig floor.

Your planned drill out/clean out will return the well to nearly the same condition before the liner was run. The plan to spot the cement back up into the casing should reestablish a seal to do the subsequent pressure test. With the cement plug in place, you can pursue the casing leak if the subsequent pressure test fails. Good luck. Please keep us informed of the progress.

Have you provided any other notice regarding loosing the fish and spotting the KO plug?? You do not need a new permit so long as you are headed to the same BHL but the misfortune does constitute a change in plans and the regulations require that we be notified. I would appreciate some further information regarding depths, hole lost, and plug volumes. Sorry to hear of the misfortune. You have been pretty successful in keeping the fishing gods at bay. Oh well, I guess a sacrifice now and then shouldn't be too bad. It won't be acceptable, but it might not be too bad. Best wishes.

In support of this request, you submitted mud weight information and surface hole mud logs gathered while drilling the four (4) existing wells on Osprey. The Commission agrees that the available information does not reveal any existing problems with pressure, hydrates or shallow gas at Osprey. Regardless of the past drilling history at Osprey, Forest must be prepared to accommodate drilling hazards that may develop over time. As each well is planned, the available information must be examined to detect any developing drilling hazards, and subsequent operations conducted accordingly. The Commission, therefore, will consider waiver of the diverter system requirement on a case-by-case basis for other wells on Osprey with surface casing set at about 2900' tvd. Requests for this waiver may be included in the application for Permit to Drill (Form 10- 401) and should include an on-going assessment of shallow hazards based on all information available at the time the permit is submitted. Your request to waiver of the diverter requirements for Redoubt Unit #4 (201-194) is approved. Sincerely, ~ ~.

Enclosed is an Application for Sundry Approvals (Form 10-403) with supporting information as required by regulation. The TDS profile from the RU #1 well indicates that salinity below the proposed setting depth of the RU #4 surface casing shoe (2893 feet TVD) is generally above 10,000 mg/l, although it occasionally drops below this threshold in some intervals. Forest Oil believes the lower salinity readings are the result of lithology changes and clay content, and not an indication of freshwater. Although freshwater is not likely below 2893 feet TVD in the RU #4 well, Forest Oil requests that the commission issue a finding under 20 MC 25.080(e)(1) that any freshwater encountered below this depth is likely to have a TDS content greater than 3,000 mg/I, and it is not reasonably expected to supply a public water system because of its location, depth and the abundant availability of water elsewhere in the region. Please call me if you or your staff have any questions about this request or require additional information. Forest Oil will be pi ~ to meet with you or answer any questions you or your staff may have. Thank You. ~ Paul D.

The proposed sening depth of the 13 3/8 inch surface casing is 2893 feet TVD (3500' lVtD) and the proposed sening depth of the 9 5/8 inch casing will be 7156 feet TVD (10500' MD). A well casing diagram and deviation protile have been previously provided in the permit to drill. 20 AAC 25.080(b)(2)-Depth to base of freshwater aquifers and permafrost, if present The total dissolved solids (TDS) content of fomlation waters in the recently completed RU # I well generally ranges between 3,000 mg/l and 10,000 mg/I from about 1832 feet (where logging began) to about 2450 feet TVD. Below 2450 feet TVD, the TDS content increases to above 10.000 mg/ I, but occasionally drops below 10.000 mg/ 1 through some intervals. Forest Oil believes the lower salinity readings are due to lithology changes and clay content, and does not necessarily indicate fresh\\iater. The TDS content in the RU #1 well generally dovetails with the Redoubt Shoal State 29690 #1 well. where salinity exceeds 10.000 mg/I below 2400 feet TVD. The TDS profile in both wells is based upon petrophysical analysis of log data using an EPA approved method for determining salinity. The RU # I well logs are included with this application~ the Redoubt Shoal State 29690 # I is on tile \\ ith the commission. At the top of the disposal zone, the RU #-1- well is near the RU # I \\ell and within one- quarter mile of the Redoubt Shoal State 29690 #1. Accordingly. the salinity profile for the RU #-1- well should correlate well with both the RU # 1 and the Redoubt Shoal State 29690 # I wells. Although it is unlikely that fresh\\ater will be encountered below the sening depth of the surface casing shoe at 2893 feet TVD. Forest Oil requests commission authorization under 20 AAC 25.080(e)( I) to dispose of drilling \\astes into any freshwater that may exist in the RU #-1- well below this depth. Formation water in the RU #-1- well is not likely to suppl~ a public \\ater system because of its location and depth. and the abundant availability of water elsewhere in the region. There is no permafrost in the area. 20 AAC 25.080(b)(3)-Stratigraphic Description The interval proposed for annular disposal in the RU #-1- \\ell is between 2893 feet and 62-1-3 tèet TVD, and corresponds to the Upper Tyonek Formation in this area. The Upper Tyonek is tlu\ial in nature and. at the well location. consists primarily of anastomozing stream channels. producing blanket-like sand intervals that are continuous both horizontally and \'ertically. Interbedded with the Tyonek sands are numerous layers of impermeable tuffaceous siltstones. carbonaceous shale and coal. Porosity and permeability are good within the Tyonek sands. The sands are very friable and generally medium grained. well-rounded and well-sorted. Porosities range from 20 ~Io to 30 ~/o. These sands should readily accept fluids proposed for annular disposal in the RU #-1- well. Overlying the Tyonek Formation is approximately 1600 feet to 1800 feet of Beluga Formation. The Beluga Formation is also fluvial. but stream channels are less numerous and more isolated by siltstone. clay and coal deposits and than in the Tyonek. Based upon the mud log from the Redoubt Shoal State 29690 # I \vell. at least 440 feet of clay and 170 feet of siltstone within the Beluga section (be1\veen 700 feet and 1800 feet) overlies the disposal zone. Combined with the siltsones. shales and coals within the Tyonek Formation. these impenneable layers provide significant and numerous barriers to upward migration of any fluids disposed through the RU #3 annulus, and should provide adequate protection for any freshwater resource that may exist above the disposal zone. 20 AAC 25.080(b)(4)-Adjacent wells Wells within one-quarter mile of the RU #4 well include: Redoubt Shoal State 29690 # 1 and #2 \\ells Redoubt Unit # I, #2. #3 and #D I wells There are no publicly recorded water wells within one mile of the RU #4 well. 20 AAC 25.080(b)(5)-Types and \olume of waste Drilling waste proposed for annular disposal in the RU #4 well \\ill be limited to that allowed under 20 AAC 25.080(h)( I) & (2). Forest Oil estimates that no more than 10,000 barrels of drilling waste. with an average density of 10 ppg to II ppg. from drilling the RU #4 \\ell will be disposed through the annulus. The bulk of waste material will be a waste slurry. composed of drilling muds and cunings with additives and water. Forest Oil has installed grind and inject equipment on the Osprey Platform to process drill cunings for disposal. Some rig wash. domestic waste and produced waters will also be disposed. Forest Oil also requests approval to use the RU #4 well annulus to dispose of drilling waste from other wells on the platform. and is aware of the 35.000 bbl and one year disposal restriction under 20 AAC 25.080(d). 20 AAC 25 .080( I )( 6 )-Other wastes No other waste other than wastes defined under 20 AAC 25.080(h)( I) & (2) are proposed for disposal. 20 AAC 25.080(b)(7)-Anticipated pressure The maximum anticipated pressure at the outer casing shoe during disposal operations should be approximately 2753 psi. This is based upon an equivalent mud weight of 18.3 ppg. Injection pressures necessary to dispose of whole mud in the RU # I and RU #2 annuli \\ere in this range. AOGCC has agreed to a maximum equivalent mud weight on RU #2 of 18.3 ppg. as per the e-mail from Tom ]\:Iaunder dated April 5. 100 I, 20 AAC 25.080(b)(8)-Cementing details Cementing records and the results of the formation integrity test on the surface casing will be submitted once these operations are complete. Forest Oil will take special precautions to ensure a good cement job with the RU #4 well. The size of the surface hole was increased to 18 1/2 inches and centralizers will be used on the 13 3/8 inch surface casing. The casing will be cemented in place in two stages using a cement stage collar at 2.000 feet. To aid in cement displacement. the casing is to be reciprocated during cementing operations. The setting depth of the RU #4 surface casing may be above the base of freshwater, as defined under commission regulations. Although TDS content in the RU # 1 well generally exceeds 10,000 mg/l below 2900 feet TVD. it occasionally drops below this threshold in some intervals. As stated above. Forest Oil believes the lower salinity readings are the result of lithology changes and clay content. and not an indication of freshwater. Although freshwater is not likely below 2893 feet TVD in the RLJ #4 well, Forest Oil requests that the commission issue a finding under 20 AAC 5.080(e)( I) that any freshwater encountered below this depth is likel) to have a TDS content greater 3.000 mg/I. and it is not reasonably expected to supply a public water system because of its location. depth and the abundant availability of water else\vhere in the region. 20 AAC 25.080( I )(9)-Casing strength Casing Joint Strength K Ibs. 1545 1122 Body Strength K Ibs. 1556 1086 Burst Psi 5050 6870 Collapse Psi 2260 4760 13 3/8" 68# L-80 BTC 9 5/8' 47# L-80 BTC 20 AAC 25.08(b)( I O)-Downhole pressure The downhole pressure obtained during the leak off test will be submitted once the operation has been completed. 20 AAC 25.080(b)( 11 )-Hydrocarbon zones No significant hydrocarbon zones are anticipated above the setting depth of the 9 5/8 inch casing at 7156 feet TVD. 20 AAC 25.0800( 12)-Duration Disposal of drilling wastes generated from the drilling of the RU #4 well will not exceed 90 days in duration.
