Caldwell C. M. #4 (API 42-429-33931) is a well in Stephens County operated by Parker Energy Company, completed March 25, 1984 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 28, 1983, permitted to 3,471 ft.
It was permitted by Mcnallen Oil CO., Inc. and has since transferred to Parker Energy Company on the wellbore schedule.
Completion filings report one formation top, including Caddo.
Its lease has reported 150K barrels of oil and 3.64K mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by McNallen Oil Co., Inc.; the EWA schedule now lists a different operator.
