Zapata County · J. C. Martin (Wilcox 8150) field · SWR-10-Well · Vertical

Fields on the latest permit · any of 2: J. C. Martin (Wilcox 8150) · La Perla (Lobo Cons.); Not one formation; the well must be completed in one of them, and no target formation is stated. The district's wildcat field is also on the permit.

Mecom J. W. #105 (API 42-505-34009) is a well in Zapata County operated by Paleo Oil Company LLC, completed October 31, 1999 and listed as swr-10-well on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued September 20, 1999, permitted to 10,400 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 6 formation tops, including Wilcox, Lobo Unconformity, Lobo 1 Sand, Lobo 3 Sand.

Its 2 leases have reported 5 barrels of oil and 576K mcf of gas since October 1999, last reporting volume in March 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
