Shankles J. M. #1
Grayson County · Grace-Mag (Penn Cordell) field · Vertical
Shankles J. M. #1 (API 42-181-31012) is a well in Grayson County operated by Grace Petroleum Corp., completed February 22, 1984.
The RRC has issued 2 drilling permits between 1983 and 1992, permitted to 12,625 ft.
It was permitted by Geodyne Operating Company and has since transferred to Grace Petroleum Corp. on the wellbore schedule.
Completion filings report 5 formation tops, including Baker, Davis, Cordell, Pennsylvanian.
Its 2 leases have reported 98.7K barrels of oil and 146K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
