Eastland County · Eastland County Regular field · Injection · Vertical
Harpool H.G. #4 (API 42-133-31324) is a well in Eastland County operated by Eastland Operating L.L.C., completed December 22, 1987 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued January 23, 1978, permitted to 4,000 ft.
It was permitted by Ranger Energy CO. and has since transferred to Eastland Operating L.L.C. on the wellbore schedule.
Completion filings report one formation top, including Lake Sand.
Its lease has reported 622 barrels of oil and 4.29K mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 13.3K barrels injected in the 12 months reported through April 2026.
