Rountree #B 51 (API 42-331-33765) is a well in Milam County operated by Winchester Oil & Gas LLC, completed September 25, 2011 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued May 5, 2010, permitted to 900 ft.

It was permitted by Omni Oil & Gas, Inc. and has since transferred to Winchester Oil & Gas LLC on the wellbore schedule.

Completion filings report one formation top, including Navarro.

Its lease has reported 433K barrels of oil and 49 mcf of gas since January 1993, last reporting in July 2026. The lease carries 241 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 160 barrels injected in the 12 months reported through July 2023.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
