Bexar County · Somerset field · Producing · Vertical
Rivas #1 (API 42-029-34178) is a well in Bexar County operated by Calfas Oil LLC, completed November 30, 1983 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 15, 1983, permitted to 1,840 ft.
It was permitted by Seeker Oil Company, Incorporated and has since transferred to Calfas Oil LLC on the wellbore schedule.
Its lease has reported 2.53K barrels of oil and 6 mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 4 wells, so these are lease totals, not this well alone.

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.

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.
