Dawson County · Key West (Spraberry) field · Vertical
Key West Waterflood Unit #1 (API 42-115-31950) is a plugged well in Dawson County, plugged September 18, 2002, last operated by Momentum Energy Corporation.
The RRC has issued 2 drilling permits between 1983 and 1984, permitted to 7,900 ft.
It was permitted by Henry Petroleum Corp. and has since transferred to Momentum Energy Corporation on the wellbore schedule.
Completion filings report 6 formation tops, including Rustler, Yates, San Andres, Glorieta.
Its 2 leases have reported 737K barrels of oil and 183K mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 18 wells, so these are lease totals, not this well alone.
Operator of record
