Bitler-Lowe Clearfork Unit #20
Andrews County · Fullerton field · Shut In · Vertical
Bitler-Lowe Clearfork Unit #20 (API 42-003-39443) is a well in Andrews County operated by Highmark Energy Operating LLC, completed July 15, 2005 and listed as shut in on the RRC schedule, shut in June 1, 2019.
The RRC has issued one drilling permit, issued January 31, 2005, permitted to 7,255 ft.
It was permitted by Cog Operating LLC and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.
Completion filings report 2 formation tops, including San Andres, Clear Fork.
Its lease has reported 2.57M barrels of oil and 1.15M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 50 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.
Wells nearby
Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
