Starr County · Bob West (L-1-4) field · SWR-10-Well · Directional
Sandia C #4 (API 42-427-33429) is a well in Starr County operated by Merit Energy Company, completed June 6, 2002 and listed as swr-10-well on the RRC schedule.
The RRC has issued one drilling permit (amended twice), issued November 29, 2001, permitted to 13,475 ft.
It was permitted by El Paso Production Oil & Gas CO. and has since transferred to Merit Energy Company on the wellbore schedule.
Completion filings report 6 formation tops, including L-1, L-5, L-7, L-10.
Its 4 leases have reported 19 barrels of oil and 3.34M mcf of gas since May 2002, last reporting volume in April 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
