Dimmit County · Elaine (San Miguel) field  · Vertical

Elaine Field /San Miguel/ Unit #66 (API 42-127-00227) is a plugged well in Dimmit County, plugged November 14, 1994, last operated by White Marlin Operating CO LLC.

The RRC has issued one drilling permit, issued May 25, 1984, permitted to 4,560 ft.

It was permitted by Tesoro Petroleum Corporation and has since transferred to White Marlin Operating CO LLC on the wellbore schedule.

Completion filings report one formation top, including San Miguel.

Its lease has reported 194K barrels of oil and 22.5K mcf of gas since January 1993, last reporting in July 2026. The lease carries 42 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
