Chambers County · Anahuac field · Directional
Zappe Marie #28 (API 42-071-31071) is a well in Chambers County operated by Texas Petroleum Investment CO., completed May 4, 1984.
The RRC has issued 2 drilling permits (amended once) between 1980 and 1997, permitted to 7,700 ft.
It was permitted by Exxon Corp. and has since transferred to Texas Petroleum Investment CO. on the wellbore schedule.
Completion filings report 4 formation tops, including Discorbis, Marg. 1, Marg 2, Frio.
Its 3 leases have reported 515K barrels of oil and 12.3M mcf of gas since January 1993, last reporting in July 2026. The leases carry 22 wells, so these are lease totals, not this well alone.
