Clark L. C. #40 (API 42-431-33229) is a well in Sterling County operated by Gilstrap Joel, completed May 6, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued April 1, 2008, permitted to 1,400 ft.
It was permitted by Levens, C. H. and has since transferred to Gilstrap Joel on the wellbore schedule.
Completion filings report 2 formation tops, including San Andres, San Angelo.
Its lease has reported 1.25M barrels of oil and 145 mcf of gas since January 1993, last reporting in July 2026. The lease carries 30 wells, so these are lease totals, not this well alone.
