This two-year development program, was designed to drill four wells and one workover during the 1990-1991 winter drilling season, and up to four wells during the 1991-1992 winter drilling season. The field is located about 18 miles southwest of Barrow, Alaska, and was accessible by an ice road connecting with the Barrow Gas Field road. The Walakpa No. 7 well is located 1274 feet from the north line and 1025 feet from the east line of Section 23, Township 20 North, Range 20 West, Umiat Meridian, Alaska. Alaska State Plane coordinates are x = 613,486 and y = 6,244, 134, Zone 6. The Kelly Bushing elevation of this well is 48.39 feet above sea level. All depth measurements are in reference to this datum unless otherwise specified. Walakpa No. 7 was the furthest northwest stepout well in the Walakpa Development Program. This well was drilled about 2.2 miles west of Walakpa No. 4, which tested gas in the Lower Cretaceous (Neocomian) Walakpa Sandstone. Based on seismic and well data correlation, the No. 7 well was interpreted to encounter the Walakpa Sandstone at a structurally intermediate level, between Walakpa Nos. 3 and No. 4. The objectives of the Walakpa No. 7 well were to test and develop the Walakpa Sandstone. The prognosis depth of the Walakpa Sandstone was 2,270 feet. The productive zone was forecast to be 25 feet thick. Walakpa No. 7 was spudded on March 11, 1992, and was drilled to a total depth of 2425'. On April 9, 1992, the well was completed as a gas well with perforations of 12 shots per foot in the Walakpa Sandstone from 2260' to 2290'. The well is presently shut in awaiting pipeline facilities. The Department of Industrial Development of the North Slope Borough supervised and directed the drilling and support operations for this well through their Barrow Gas Field Development Project. All engineering and drilling operations were managed by Allen and Crouch, Petroleum Engineers. Geological matters were supervised by ASCG, Incorporated. Jade Drilling Company, Ltd. was the drilling contractor.

In Walakpa No. 7, the Walakpa Sandstone consists of brown, fine grained, moderately sorted sandstone. Sandstone grains are predominantly clear quartz. Accessory grains include carbonaceous (wood?) fragments, pyrite, shell fragments, bentonite, and glauconite. The gamma ray log of the No. 7 well indicates sandstone from 2258' to 2289'. Log porosities of the sandstone interval average 25 %. Density porosity logs are greater than 18 % from 2260' to 2286'. Formation density and neutron porosity logs show continuous crossover from 2261' to 2284'. The lowermost four feet of the sandstone interval is interpreted to be tight and non-productive. In general, resistivity of the Walakpa Sandstone is relatively uniform throughout the zone. The upper eight feet of the sandstone interval is a zone of higher resistivity, with a maximum deep resistivity of 85 ohm-m, the remainder of the interval averages about 30 ohm- m. Three half-foot intervals, at 2280', 2284' and 2287' show high shallow resistivity readings, and are interpreted to be tight zones of increased cementation. The Walakpa Sandstone in Walakpa No. 7 has a gross pay thickness of 29 feet. Log analysis indicates a net pay sand of 25 feet. WELL WALAKPA WELL PROGNOSIS AND NO. 7 SUMMARY PROGN.

INC. STRUCTURE Introduction The Walakpa Sandstone reservoir is located on the south side of the Barrow structural high, often referred to as the "Barrow high". This subsurface high marks the northern edge of the Colville Basin which trends northwest from Prudhoe Bay extending through Barrow and on into the Chukchi Sea. In general, strata on the south side of the Barrow high are south-dipping and relatively unfaulted. In the Walakpa Gas Field area, strata dip to the south at about 2 degrees. Walakpa Nos. 1 and 2 were drilled on this regional south-dipping structure by the Husky/ONPRA in 1978 and 1981, respectively. Both of these wells encountered the gas-bearing Lower Cretaceous Walakpa Sandstone, and identified a minimum gas column of 550 feet if reservoir continuity is assumed. The 1991 North Slope Borough drilling program followed a progressive step-out, both laterally and updip, from Walakpa No. 2. Of the two original Walakpa wells, Walakpa No. 2 showed the most favorable conditions in the Walakpa Sandstone. The 1992 drilling season involved stepout drilling to the west, on 640-acre spacing, to test the lateral continuity of the Walakpa Sandstone reservoir. Structural Position Walakpa No. 7 is nearly equidistant from the Walakpa Nos. 3 and 4 wells, located about two miles to the southeast and northeast, respectively. Structurally, the No. 7 well is at an intermediate level, approximately 90 feet downdip from Walakpa No. 4, and 115 feet updip from Walakpa No. 3. Walakpa No. 7 well was drilled to confirm the lateral continuity of the gas-beating Walakpa Sandstone in the northwestern end of the development area. The well is also located near a structural inflection interpreted from seismic data, where dips change from predominantly south-dipping (as in much of the development area) to southwest-dipping. The well was situated downdip of the Walakpa No. 4 well to encounter potentially warmer reservoir temperatures, yet high enough to maximize gas recovery. Drilling of the No. 7 well confirmed the northwestward continuity of the Walakpa sandstone reservoir. I~o ,, 111T20N I I 1 ! -N~)zT---No dO--m- , O I ! ! I I ! 'No. 8 o , No°. I I 1 !

Therefore, no hydrocarbon shows above the Walakpa Sandstone in the mud or the cuttings were recorded. The cuttings from the Walakpa Sandstone gave off pale to bright yellow fluorescence under ultraviolet light. PRODUCTIVE ZONES The gamma ray log of the Walakpa No. 7 well indicates good sandstone development in the Walakpa Sandstone from 2259' to 2288'. Formation density/neutron porosity logs indicate gas-bearing porous sandstone from 2259' to 2286'. The lowermost two feet of the Walakpa Sandstone is interpreted to be tight and non-productive. Continuous perforations covered the following interval: KB DEPTH 2260'-2290' NET THICKNESS 30' SHOTS PER FOOT 12 No other productive zones were encountered in this well. CONCLUSIONS The objective formation of Walakpa No. 7, the Walakpa Sandstone of the Lower Cretaceous (Neocomian) "pebble shale", was encountered at 2259'. This formation was found to be gas-bearing, and Walakpa No. 7 was completed as a gas well with perforations of 12 shots per foot from 2260' to 2290'. No other productive zones were encountered in this well. Walakpa No. 7 confirmed the northwestward continuity of the gas-beating Walakpa Sandstone. At Walakpa No. 7 the Walakpa Sandstone is a brown, fine-grained, moderately sorted sandstone. The unit has a gross thickness of 29 feet, with 25 feet of net pay. Log porosites of the perforated interval average 25 % Log analysis indicates porous, gas-bearing sandstone from 2260' to 2286', with several half-foot thick zones of reduced porosity. The lowermost two feet of the Walakpa Sandstone is interpreted to be tight and non-productive.
