Cowden Jax M B #71 (API 42-103-34631) is a well in Crane County operated by Hilcorp Energy Company, completed March 14, 2007 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued April 10, 1998, permitted to 5,598 ft.
It was permitted by Exxon Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 4 formation tops, including San Angelo, Tubb, Devonian, Silurian (undifferentiated).
Its lease has reported 293K barrels of oil and 294K mcf of gas since May 1998, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
