Northwest Stevens A4, A5, and A6 reservoirs, Elk Hills Field, Kern County, California. General reservoir study: evaluation and MER determination. Final technical report

Technical Report · Thu May 01 04:00:00 EDT 1986

OSTI ID:5164937

The primary conclusion is that historically, and particularly in the last four months, the Northwest Stevens A4-A6 Sand waterflood has operated in a state of underinjection. Injection should immediately be increased as necessary to replace current reservoir withdrawals and, as soon as possible, injection rates should be increased to around 26,000 BWPD to accelerate the project and maximize its economic returns. Meanwhile, a MER value of 7243 barrels of oil per day is recommended for the remainder of 1986. This report contains backup data, tables, exhibits, and calculations to support the conclusions and recommendations that are presented. Appended items are included in Appendix Book 1 and Appendix Book 2. 20 figs.
