John Gresham Unit #1H (API 42-289-31986) is a horizontal well in Leon County operated by Comstock Oil & Gas LLC, completed March 31, 2012 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 10, 2011, permitted to 20,000 ft.
It was permitted by Encana Oil & Gas(USA) Inc. and has since transferred to Comstock Oil & Gas LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Austin Chalk, Pecan Gap.
Its lease has reported 246K barrels of oil and 80K mcf of gas since March 2012, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
