An Engineering and Economic Analysis of the Soldotna Creek Unit, Swanson River Oil Field, Alaska
Abstract/Contents
- Abstract
- The high pressure gas injection process under way at the Swanson River Oil Field is analyzed. The emphasis is directed solely at the Soldotna Creek Unit Fault Block. The thesis evaluates the recovery efficiency of the dry gas injection process, possible future production based on three distinct production schemes, and the economics of the project based on today's values.The recovery model applied in the reservoir analyses made incorporates microscopic pore displacement with areal sweep and vertical coverage. The Kern (Trans. AIME, 1952) technique is used to determine pore displacement recovery. A standard staggered line drive pattern is used as the unit production pattern. Areal sweep data were taken from Dyes, Caudle and Erickson (Trans. AIME, 1954) and vertical coverage curves came from Dykstra and Parsons (Secondary Recovery of Oil in the United States, 2nd Ed., API (1950)). A comparison of the overall technique used here with that presented by Young, e_t aL (J. Pet. Tech., 1977) is examined and shown to match actual production data to a high degree.Future production based on three possible production schemes was analyzed. The three methods tested were: (1) full pressure maintenance, (2) gas injection rates equal the gas production rates, and (3) no future gas injection. Under the latter two conditions, various pressure-decline schemes were assumed with oil and gas production analyzed.The final part dealt with the economics of the gas injection project based on today's market conditions. The past 13 years of production were modelled as if they started today and extended into the future. Cost data v/ere obtained for the parameters involved along with their associated spreads. Only oil and purchased gas price escalation rates were varied. The output of discounted net cash flow and its probability distribution was obtained for each case and distinct conclusions as to the economic feasibility were defined.
