Wooldridge Mack H. A #1-552 (API 42-417-34032) is a well in Shackelford County operated by Snyder Drilling Corp., completed July 16, 1986.

The RRC has issued one drilling permit, issued July 1, 1981, permitted to 1,000 ft.

It was permitted by Lhg Resources, Inc. and has since transferred to Snyder Drilling Corp. on the wellbore schedule.

Completion filings report 2 formation tops, including Fry, Frye Sand.

Its 2 leases have reported 10.8K barrels of oil and 217 mcf of gas since January 1993, last reporting in July 2026. The leases carry 6 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 147 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.
