Accordingly,' the Commission will, in its discretion, issue an order without a public hearing. ~FINDINGS: 1. Favorable injectivity data, using filtered Cook Inlet water, was obtained from an acid treatment of well G-30L which was completed in the West Forelands Oil Pool. Conservation Order No. 226 January 23, 1987 Page 2 · · The water injection activity is expected to commence in mid-1987 and will include from. 8 to 10 injection wells. Engineering studies show that waterflooding may increase recovery of the original oil in place by 5% for an incremental increase in oil recovery from the West Forelands Pool of 4.3 million barrels more than obtainable by primary depletion methods. CONCLUSIONS: I · Reservoir performance indicates the feasibility of enhanced recovery operations by a waterflood project in this pool. · The project will result in the recovery of oil from the West Forelands Pool that would not otherwise be producible. · The project will not create waste, and correlative rights are protected. NOW, THEREFORE, IT IS ORDERED THAT: Rule 4 of Conservation Order No. 80 is amended to read as follows: The injection of water for the purpose[S] of [PRESSURE MAINTENANCE, SECONDARY] enhanced oil recovery, or [OF] conducting injectivity tests is hereby permitted in the McArthur River Hemlock Oil Pool, the McArthur River Middle Kenai "G" Oil Pool, and the McArthur River West Forelands Oil Pool. A semiannual progress report detailing project operations and results shall be submitted ~to the Commission in January and July of each year.

An acid treatment was performed on G-30L on October 22, 1976 when the well was completed as a West Forelands producer. The injection rate, pressure, and volumes during the treatment were as follows: Maximum injection rate Maximum surface pressure Total fluid injected 3,600 B/D 2,000 psi 1,089 Bbls Please call if you have additional questions.
