Box 1635 Houston, TX 77251 Dear Mr. Moxley: ql-ioel Final Closure of the Kustatan #1 Site located in Section 3, T $ N., R 15 W., SM on the West Side , of Cook Inlet aD~roximatelv" ~ - ' ,. . .:-._, miles west of Trading Bay. , .~, ,~ C- Solid Waste Disposal Permit # 9123-BA008 --¢_'¢- x ; ~ . ' '"'~ ~ . The Alaska Department of Environmental Conservation (ADEC) has reviewed the post closure monitoring report, Document Number 1420-094 dated October 1996, for the KustatanNo. 1 Reserve Pit Site and your notification that the five-year post closure visual and surface water monitoring pro=m-am has been completed. q-]ne requirement to visually monitor the site and collect surface and =m'ound water samples was included as a condition of closure in the permit number 9!23-BA008, dated October 10, 1991. At closure, 7,400 cubic yards of drilling waste was completely encapsulated by a bottom liner and sealed with a top line, soil cover was placed, the surface contoured, and the site reseeded. The requirement to file as-built drawings of the solid waste disposal facility with a land records office was waved by Mr. Ron Godden with the solid waste pro=m-am of ADEC on April 1, 1992. It was determined that the as-build drawings provided to ,a/DEC would satisfy that requirement. Back~ound surface and pound water samples were collected in 1991 before any drilling waste was deposited at the site. These data established a hi~ natural backg-round of chromium (380/2~d~L) and barium (1900~dL) in the g-round water/soils at the location. All subsequent years of sampling show various anomalies of slightly elevated chromium and barium values in the monitoring wells. However, all values except one were below the back~ound concentrations established in 1991. In 1996, chromium values of 1100/2glL were indicated in monitoring well #1. This value exceeded previous background data, however, the pH of the groundwater sample was a neutral pH (.7.2). High concentrations of dissolved chromium in water would required an acid pH. This source of chromium is likely particulate material from the soils surrounding the well casing. Particulate chromium from the soils is not considered an indicator of leachate from the reserve pit.

Chevron USA, Kustatan ~1 PTD 91-109,Sec 3 T8N R9W SM __- Friday, Ju.ly 10, I arrived at ERA facilities at about 8:30 am and met Emily Davies, Chevron and Rick Smith, DNR Fairbanks. We traveled by ERA helicopter to Chevron's Kustatan ~1 location. Weather was overcast, fog and rain. Subject well was drilled this past spring; the location was cleaned, graded, and revegetated in February, after rig move-out. The location is about 8 miles west of the Trading Bay onshore facilities; about 0.? miles northerly of the Cook Inlet Pipeline service road. The location is on a ridge; it gently slopes away from the ridge toward a wooded area which is interspersed with muskeg. The location is large, 8 or 3 acres, and is mostly surrounded by trees. Grass is growing over about ?OK of the location. The ground surface is rough and the soil is soft, high loft, not mud. There is no standing water in the low places. The location is junk free (we brought back 8 pieces of pipe). There are small diameter pipes extending above ground which mark the location of the reserve pit: per Chevron, DEC requires they maintain these markers for 5 years. The marker post is in the central area of the location: bead welded on the post is the following: CHEVRON USA ADL 369156 KUSTATAN ~1 1530 FNL 3891FWL SEC 3 (survey shows 1535 & 3911) TSN RI5W SEWARD B & M Rick Smith and I walked the access road to the pipeline service road. The trees cleared during road construction littered the access road. The road was wet and soggy in most areas; however, it was raining and the road did traverse some muskeg areas. Erosion was not noted in any area. Rick and I agreed that it would have been better if the location were smoother and the road slash burned or buried. However, there is no junk, no evidence of current or pending erosion, and any attempts to make improvements would result in increased environmental damage. Rick plans to accept the road and location "as is". Summary: An AOGCC Surface Aband.Report is attached. I recommend that the Commission accept the location "as is" and issue a Location Clearance to Chevron for their Kustatan ~1 well location. A proposed letter is attached for your signature.

This iocat~o _ s%~ted a ~ n pre peculiar situation ~n that the grade level was lowered by scraping the topsoil outwards, which created a substantial (5'-15') berm around the location. The rig sat on the south end of the pad with the vent line running north. The line was bifurcated~ but I felt that its alternate leg was too far out to give a good downwind alternate. At my request, the alternate leg was moved closer to the rig and extended further west. Kerry Giriinghouse and Dan Sheehan (Chevron reps) were very receptive ~ u~ my co~nents and requested return visits .by the inspectors. In summary, after repositioning the alternate diverter ].eg, I approved the rig to drill surface hole on Chevron' s Kustutan #1.

We believe that the chance of encountering H2S is extremely unlikely at Kustatan No. 1. The Hemlock formation has been tested by numerous wells throughout the Cook Inlet. Initial conditions have been sweet. Hydrocarbon production has turned sour only after water flooding. Attached are various Hemlock water and gas sample analyses which support the above. In addition, Kustatan River #1 is 6,400 ft., Kustatan Ridge #1 is 17,200 ft. and W. Foreland State #1 is 8550 ft. from the subject well. None of the aforementioned wells encountered H2S. As a prudent operator, we do have H2S equipment available. Seacorp is to provide electronic detectors for the bell nipple and shaker. The detectors will include both visual and audible alarms. The mud contractor is supplying a Draeger gas detector and a Garrett Gas Train. Seacorp will also be supplying portable fresh air packs which would allow the well to be shut in. Mud materials include sufficient caustic soda to increase the pH above 10. The above equipment will be in place prior to drilling out the 9-5/8" shoe. RECEIVED JAN t 1 ~,99~ Alaska Oil & Gas Cons. Commission Anchorage Chevron believes that adequate precautions for H2S have bean undertaken at Kustatan No. 1. We respectfully request that a H2S Contingency Plan not be required for this well and that the safety measures detailed herein satisfy your requirements. In either case, your prompt response will be greatly appreciated so that we may comply without a delay in rig operations. Please call me at 563-2559 with any questions. Sincerely, M. K.

Johnston Chairman AOGCC 3001 Porcupine Drive Anchorage, Alaska 99501-3192 RE: ~TTSmAmA~ ~TO ~ APD NO 91-109; DIVERTER REQUIREMENTS Dear Mr. Johnston: The APD for Kustatan No. 1 specifies that a diverter be installed on the 20" casing at 50 ft. as well as the 13-3/8" casing at 250 ft. We propose installing a diverter on the 13-3/8 conductor casing at 250 ft. only. The proposed change is consistent with AOGCC regulations. Kustatan River No. 1 penetrated shallow strata in the same fault block as our proposed well, Kustatan No. 1. There was no indication of shallow gas. If gas is encountered between 50 and 250 ft., it is unlikely that 50 ft. of driven pipe would be sufficient to divert the flow. In summary, we respectfully request that a diverter not be required on the 20" casing in Kustatan No. 1. sincerely, CPBU Drilling Manager RECEIV[D D EOt 199t Alask~ 0il & Gas Oons.

Inc. submitted an application dated November 5, 1991, requesting an exception to 20 AAC 25.055 to allow drilling the Chevron Kustatan No. 1 exploratory oil well closer than 500 feet to a drilling unit boundary. . Notice of hearing was published in the Anchorage Daily News and the Anchorage Times on November 14, 1991 and the Alaska Administrative Journal Issue 48 on November 25, 1991 pursuant to 20 AAC 25.540. 3. No protests to the application were received. FINDINGS: The Chevron Kustatan No. 1 well as proposed will be directionally drilled from a surface location 1530 feet from the north line (FNL), 3891 feet from the west line (FWL) of Section 3, T8N, R15W, Seward Meridian to a bottomhole location 541 feet FNL, 2662 feet FWL, Section 3, T8N, R15W, Seward Meridian. 2~ All offset operators/owners have been identified and duly notified of Chevron's application. 3~ An exception to 20 AAC 25.055(a)(1) is necessary to allow drilling of the well. Conservation Order No. 281 December 2, 1991 Page 2 CONCLUSIONS: Granting a spacing exception to allow drilling of the Chevron Kustatan No. I well as proposed will not result in waste nor jeopardize correlative rights. NOW, THEREFORE IT IS ORDERED: Chevron U.S,A. lnc.'s application for an exception to 20 AAC 25,055 for the purpose of drilling the Kustatan No, I well is approved as proposed.

Inc. requests approval of the enclosed revised application for a Permit to Drill the Kustatan #1 exploratory well. The original application was approved September 5, 1991 by your commission. Chevron would now like to intentionally deviate the well up dip from the surface location. The proposed well plan is attached with the revised application. Since the new bottom hole location is within 500' of the quarter section line, Chevron requests an exception to 20 AAC 25.055. As can be seen in the attached plat, Chevron U.S.A. is the owner on all adjacent quarter sections, and there are no producing wells in any of the adjacent sections. The surface location of the well is to be located on the State of Alaska Oil and Gas Lease ADL 369156, 1530' FNL 3891' FWL of Section 3, Township 8 North, Range 15 West, Seward Meridian, and the bottom hole location will be 541' FNL 2662' FWL of the same section.

E. Whitehill From: F. S. Eastwood Re: Kustatan Proposed Well ITT Curve The Alaska onshore group requested my assistance in generating an ITT curve in order to satisfy state requirements for obtaining a drilling permit at the Kustatan River prospect. What follows is a description of the procedures involved in generating the ITT curve at the proposed location and a discussion of the accuracy of the result using 3 outpost wells. Methodology Stacking velocity analysis was performed on line Ci-88-1, at three locations centered at SP 225, using the ADVANC program. Dip corrected velocity picks were culled by hand, and are plotted in figure 1. A standard least squares fit to the data points was performed ( assuming an additive cubic spline model, with zero intercept fixed ). Upper and lower confidence bounds are also plotted in figure 1. Also illustrated is the conversion of this stacking velocity function to interval velocity using Dix's Equation. Notice the associated broadening of the confidence bounds. Conversion to depth was accomplished using the least squares estimate, and is illustrated in figure 2. Finally the ITT curve presentation is accomplished by inverting the velocity to transit time and plotting on a log scale, see figure 3. The reliability of this methodology to actually predict sonic log transit times in this area will be discussed next. Outpost Wells Stacking velocity analysis was repeated at three nearby well locations: (1) Shell Kustatan River #1, and seismic line CI-88-7, SP 346. (2) Cities W. Forelands State A #1, and seismic line Cl-87-1, SP 130. (3) Shell Kustatan Ridge-State #i, and seismic line Cl-88-7, SP 206 The results are illustrated in figures 4 thru 6. The velocities were then converted, to depth and plotted-with the smoothed (50 ft running averages) sonic logs overlain, see figures 7 thru 9. Overall~ the fit between the-. observed seismic and-sonic log velocities is fair to poor. The-log velocities are barely contained by the confidence limits. Certainly details and changes in slope are poorly resolved by the seismic velocities. This result is not entirely unexpected as near surface variability, structural complexity and Io signal/noise ratio combine to produce extremely complicated stacking velocity patterns. When converted to interval velocities using Dix's formula these estimates yield unreliable interval velocities. Further evidence of the Io relaibility of the seismic velocity predictions is illustrated in figure 10. Overlaying all the sonic logs on the same plot hilights a consistent linear trend of velocities at all three outpost wells. However, from the seismic predictions at those locations it would be difficult to discern that same simple relationship. Conclusions Due to the limited agreement between the seismic and log velocities at the outpost wells I would be sceptical of interpreting too much detail in the ITT curve at the proposed location.

E. Whitehill From: F, S. Eastwood Re: Kustatan Proposed Well ITT Curve The Alaska onshore group requested my assistance in generating an ITT curve in order to satisfy state requirements for obtaining a drilling permit at the Kustatan River prospect. What follows is a description of the procedures involved in generating the ITT curve at the proposed location and a discussion of the accuracy of the result using 3 outpost wells. Methodology Stacking velocity analysis was performed on line CI-88-1, at three locations centered at SP 225, using the ADVANC program. Dip corrected velocity picks were culled by hand, and are plotted in figure 1. A standard least squares fit to the data points was performed ( assuming an additive cubic spline model, with zero intercept fixed ). Upper and lower confidence bounds are also plotted in figure 1. Also illustrated is the conversion of this stacking velocity function to interval velocity using Dix's Equation. Notice the associated broadening of the confidence bounds. Conversion to depth was accomplished using the least squares estimate, and is illustrated in figure 2. Finally the ITT curve presentation is accomplished by inverting the velocity to transit time and plotting on a log scale, see figure 3. The reliability of this methodology to actually predict sonic log transit times in this area will be discussed next. Outpost Wells Stacking velocity analysis was repeated at three nearby well locations' (1) Shell Kustatan River #1, and seismic line Cl-88-7, SP 346. (2) Cities W. Forelands State A #1, and seismic line Cl-87-1, SP 130. (3) Shell Kustatan Ridge State #1, and seismic line CI-88-7, SP 206 The results are illustrated in figures 4 thru 6. The velocities were then converted to depth and plotted with the smoothed (50 ft running averages) sonic logs overlain, see figures 7 thru 9. Overall the fit between the observed seismic and sonic log velocities is fair to poor. The log velocities are barely contained by the confidence limits. Certainly details and changes in slope are poorly resolved by the seismic velocities. This result is not entirely unexpected as near surface variability, structural complexity and Io signal/noise ratio combine to produce extremely complicated stacking velocity patterns. When converted to interval velocities using Dix's formula these estimates yield unreliable interval velocities. Further evidence of the Io relaibility of the seismic velocity predictions is illustrated in figure 10. Overlaying all the sonic logs on the same plot hilights a consistent linear trend of velocities at all three outpost wells. However, from the seismic predictions at thoSe locations it would be difficult to discern that same simple relationship. Conclusions Due to the limited agreement between the seismic and log velocities at the outpost wells I would be sceptical of interpreting too much detail in the ITT curve at the proposed location. As an example it is possible that the Io velocity zone at 3300', predicted by the seismic, is purely an artifact much the same as the the Io velocity zone, predicted by the seismic, at 4200' in the Cities West foreland well. If you have any further questions regarding the accuracy or reliability of the seismice velocity predictions I would be glad to go over the work with you.
