Holt Sand Unit #0-101 (API 42-337-31534) is a well in Montague County operated by Wako Oil CO. LLC, completed May 5, 1981 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued December 23, 1980, permitted to 1,800 ft.

It was permitted by Arco Oil & Gas CO. and has since transferred to Wako Oil CO. LLC on the wellbore schedule.

Completion filings report one formation top, including Holt.

Its lease has reported 345K barrels of oil and 545 mcf of gas since January 1993, last reporting in July 2026. The lease carries 63 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 137K barrels injected in the 12 months reported through July 2025.

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