GMC Data Report No. 21~05 Schoon Street. Anchorage, Alaska 99518-3045, (907) 349·3541 Fax (907) 344-2823 1/8 INTRODUCTION Core Laboratories was requested to perform permeability and porosity measurements on behalf of Arco Alaska, Inc. for samples recovered from the Fish Creek #1 well from the North Slope, Alaska. Presented herein are the results of this study. Slabbed sections of core approximately one inch in thickness were received in Anchorage by Core Lab. personnel. A service description and methodology are presented in section 1. The core analysis results and lithological descriptions for the horizontal samples are presented in section 2. We sincerely appreciate this opportunity to be of service and hope this data prove beneficial in the development of a reservoir.

" CONVENTIONAL CORE ANALYSIS SERVICE DESCRIPTION SECTION 1 SECTION 1 CONVENTIONAL CORE Conventional Core Processing Upon arrival at Core Laboratories Anchorage facility, the slabbed sections of core were saturated with water, then placed in a freezer and allowed to freeze overnight. The one-inch routine plugs were cut parallel to bedding, through the central portion of the one inch slabs. The horizontal plugs were cut using carbon dioxide liquid as a coolant, and trimmed on a dry saw. Two samples - from 2971.5ft. and 2980.5ft. - failed and were not suitable for further analysis. The sample from 3002.3ft. was well consolidated and required no special handling. The samples from 3010.0ft. and 3014.0ft. were wrapped in lead foil with screens at each end to prevent their parting along bedding plains. Laboratory Procedures Plug Cleaninq The horizontal plugs were cleaned individually for a minimum of five day in a Dean-Stark. The plugs were considered clean when no cut fluorescence was observed using trichloroethane under UV light.. Plug Drying The horizontal plugs were dried in a convection oven at 240 F for 24 hours. All samples were cooled in a desiccator to room temperature before porosity and permeability measurements were made. Grain Densit.y Grain volume determinations were measured on desleeved samples according to Boyle's Law utilizing Helium in an Auto Porosimeter. The equipment was calibrated to yield a grain density variation of less than .005 gm/cc. Grain densities were calculated using Equation 1. Dg Mg/Vg (1) Where: Dg = Grain Density Vg = Grain Volume Mg = Grain Mass GMC Data Report No. 216 5/8 Atmospheric Porosity of Consolidated Samples The horizontal plug samples were measured for bulk volume by mercury displacement at ambient conditions. Porosity was calculated using Equation 2. P = [(Vb-Vg)/Vb)] x 100 (2) Where: P = Porosity, Percent Vb = Bulk Volume Vg = Grain Volume Atmospheric Permeability to Air Horizontal permeabilities were measured in a Hassler type core holder ata confining pressure of 400 psig after the plugs were redried overnight at 240F. Permeability calculations were performed as defined by Darcy's Equation for compressible fluids, Equation 3. Pa x v x 1000 Qa x L x L K = -------------------- x ----------- (3) (PI - P2)(Pl +P2) Vb -------- '2 Where: K = Permeability v = Gas Viscosity PI P2 = Differential Pressure PI + P2 ------- = Mean Pressure 2 Pa = Atmospheric Pressure Qa = Flow Rate L = Length Vb = Bulk Volume GMC Data Report No. 216 6/8 SECTION 2 ...
