H. L. Terry Unit #1
Brazos County · Giddings (Austin Chalk-3) field · Horizontal
H. L. Terry Unit #1 (API 42-041-31548) is a plugged horizontal well in Brazos County, plugged February 14, 2018, last operated by Enervest Operating L.L.C..
The RRC has issued one drilling permit (amended twice), issued October 28, 1991, permitted to 15,000 ft.
It was permitted by Union Pacific Resources Company and has since transferred to Enervest Operating L.L.C. on the wellbore schedule.
Completion filings report 4 formation tops, including Midway, Navarro, Pecan Gap, Austin Chalk.
Its 2 leases have reported 25.4K barrels of oil and 2.44M mcf of gas since July 1993, last reporting in April 2018. The leases carry 2 wells, so these are lease totals, not this well alone.
