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. 10 well is located 1176 feet from the north line and 1144 feet from the east line of Section 24, Township 20 North, Range 20 West, Umiat Meridian, Alaska. Alaska State Plane coordinates are x = 618,644 and y = 6,244,315, Zone 6. The Kelly Bushing elevation of this well is 42.13 feet above sea level. All depth measurements are in reference to this datum unless otherwise specified. Walakpa No. 10 was the furthest northwest stepout well in the Walakpa Development Program. This well was drilled about 1 mile southwest of Walakpa No. 4, which tested gas in the Lower Cretaceous (Neocomian) Walakpa Sandstone. Based on seismic and well data correlation, the No. 10 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. 10 well were to test and develop the Walakpa Sandstone. The prognosis depth of the Walakpa Sandstone was 2,250 feet. The productive zone was forecast to be 25 feet thick. Walakpa No. 10 was spudded on March 24, 1992, and was drilled to a total depth of 2365'. On April 19, 1992, the well was completed as a gas well with perforations of 12 shots per foot in the Walakpa Sandstone from 2220' to 2253'. 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.

NORTH[ SLOPE BOROUGH Surveyed By TS/LCMF Linni'Led 139 E. 51st Ave. AnFhoraqe, Alaska GEOLOGY Formation Tops The following formation tops were identified in the Walakpa No. 10 Well: FORMATION DEPTH (KB) SUBSEA CRETACEOUS Torok Formation "pebble shale" Walakpa Sandstone 1857' 1815' 2222' 2180' JURASSIC Kingak Shale 2250' 2208' Walakpa Sandstone: 2222' - 2250' Cuttings sample intervals and lithologic descriptions focused on the Walakpa Sandstone, the objective formation of this well. In Walakpa No. 10, 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. 10 well indicates sandstone from 2222' to 2250'. Log porosities of the sandstone interval average 22%. Density porosity logs are greater than 21% from 2222' to 2248' with the exception of a two-foot thick zone at 2244'. Formation density and neutron porosity logs show continuous crossover from 2222' to 2244'. In general, resistivity of the Walakpa Sandstone is relatively uniform throughout the zone. The upper six feet of the sandstone interval is a zone of higher resistivity, with a maximum deep resistivity of 190 ohm-m. The remainder of the interval averages about 80 ohm- m. The interval from 2244 - 2246 shows high shallow resistivity readings, and is interpreted to be a fight zone of increased cementation. The Walakpa Sandstone in Walakpa No. 10 has a gross pay thickness of 28 feet. Log analysis indicates a net pay sand of 24 feet. WELL WALAKPA WELL PROGNOSIS AND NO.

OPE CONSUl.TING GROUP. INC. Engineers · Architects · Scientists · Surveyors 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. 10 is located about one mile southwest of Walakpa No. 4, and 1.5 miles northwest of Walakpa No. 3. Structurally, the No. 10 well is at an intermediate level, approximately 60 feet downdip from Walakpa No. 4, and 145 feet updip from Walakpa No. 3. 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. 10 well confirmed the northwestward continuity of the Walakpa sandstone reservoir. I I t I I ' I Il I I I I I I I I · I I I i I I I I I -4 ....... t -+ ........ +-- -t ........

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. 10 well indicates good sandstone development in the Walakpa Sandstone from 2222' to 2250'. Formation density/neutron porosity logs indicate gas-bearing porous sandstone from 2222' to 2244'. The lowermost two feet of the Walakpa Sandstone is interpreted to be tight and non-productive. Continuous perforations covered the following interval: KB DEPTH 2220'-2252' NET THICKNESS 32' SHOTS PER FOOT 12 No other productive zones were encountered in this well. CONCLUSIONS The objective formation of Walakpa No. 10, the Walakpa Sandstone of the Lower Cretaceous (Neocomian) "pebble shale", was encountered at 2222'. This formation was found to be gas-bearing, and Walakpa No. 10 was completed as a gas well with perforations of 12 shots per foot from 2220' to 2252'. No other productive zones were encountered in this well. Walakpa No. 10 confirmed the northwestward continuity of the gas-bearing Walakpa Sandstone. At Walakpa No. 10 the Walakpa Sandstone is a brown, fine-grained, moderately sorted sandstone. The unit has a gross thickness of 28 feet, with 24 feet of net pay. Log porosities of the perforated interval indicate gas-bearing sandstone through the pay zone from 2222' to 2248', with a two foot thick zone of reduced porosity at 2244'. The lowermost two feet of the Walakpa Sandstone is interpreted to be tight and non-productive.
