Waltman #1
Brazos County · Giddings (Buda) field · Horizontal
Waltman #1 (API 42-041-31498) is a horizontal well in Brazos County operated by Martineau Petroleum Inc., completed January 30, 2001.
The RRC has issued 2 drilling permits between 1991 and 2000, permitted to 12,360 ft.
It was permitted by B.W.O.C., Inc. and has since transferred to Martineau Petroleum Inc. on the wellbore schedule.
Completion filings report 2 formation tops, including Pecan Gap, Austin Chalk.
Its 3 leases have reported 54.4K barrels of oil and 530K 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
