Cornelius L. #5

Matagorda County · Wadsworth S. (11100 Res. C) field · Vertical

Cornelius L. #5 (API 42-321-31590) is a well in Matagorda County operated by Legend Natural Gas LP, completed January 26, 1990.

The RRC has issued 4 drilling permits (amended once) between 1989 and 2019, permitted to 12,500 ft.

It was permitted by Bluefin Resources LLC and has since transferred to Legend Natural Gas LP on the wellbore schedule.

Completion filings report 7 formation tops, including Frio, Savage Sand, Lewis Sand, 10400' Sand.

Its 4 leases have reported 69.9K barrels of oil and 4.12M mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
