Dallmeyer Unit #1RE
Washington County · Giddings (Austin Chalk Gas) field · Horizontal
Dallmeyer Unit #1RE (API 42-477-30479) is a horizontal well in Washington County operated by Enervest Operating L.L.C., completed May 29, 1997.
The RRC has issued 3 drilling permits between 1982 and 2013, permitted to 12,000 ft.
It was permitted by Wcs Oil & Gas Corporation and has since transferred to Enervest Operating L.L.C. on the wellbore schedule.
Completion filings report 3 formation tops, including Navarro, Pecan Gap, Austin Chalk.
Its 3 leases have reported 34.9K barrels of oil and 2.36M mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by WCS Oil & Gas Corporation; the EWA schedule now lists a different operator.
