Balcones W Unit A #1LS (API 42-317-43570) is a horizontal well in Martin County operated by Ovintiv USA Inc., completed February 8, 2022 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued May 11, 2021, permitted to 12,500 ft.

It was permitted by Petrolegacy Energy II, LLC and has since transferred to Ovintiv USA Inc. on the wellbore schedule.

Completion filings report 10 formation tops, including Santa Rosa, Yates, Queen, Grayburg.

Its lease has reported 495K barrels of oil and 539K mcf of gas since August 2021, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
