Mecom J. W. #91 (API 42-505-33728) is a well in Zapata County operated by Paleo Oil Company LLC, completed June 2, 1998 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended twice), issued December 11, 1997, permitted to 9,995 ft.

It was permitted by Coastal Oil & Gas Corporation and has since transferred to Paleo Oil Company LLC on the wellbore schedule.

Completion filings report 8 formation tops, including Lobo Unconformity, Lobo I, Lobo Iii, Upper, Lobo Iii, Upr..

Its 2 leases have reported 7 barrels of oil and 1.68M mcf of gas since February 1998, last reporting volume in March 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

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