Calhoun County · Grass Island (Matagorda -A-) field · Vertical
State Tract 216 #13 (API 42-057-31440) is a well in Calhoun County operated by Torrent Oil LLC, completed November 6, 1987.
The RRC has issued 3 drilling permits (amended once) between 1987 and 1996, permitted to 5,900 ft.
It was permitted by Petro-Guard Company, Inc. and has since transferred to Torrent Oil LLC on the wellbore schedule.
Completion filings report 13 formation tops, including Farwell -A-, Farwell A, 4600 Sand, 4600' Sand.
Its 2 leases have reported 632K barrels of oil and 494K mcf of gas since January 1993, last reporting in July 2026. The leases carry 9 wells, so these are lease totals, not this well alone.
