Lea P. J. #55

Crane County · Sand Hills (Wichita-Albany) field · Vertical

Lea P. J. #55 (API 42-103-34281) is a well in Crane County operated by Mobil Producing TX. & N.M. Inc., completed February 15, 1995.

The RRC has issued 3 drilling permits (amended once) between 1994 and 2022, permitted to 6,400 ft.

It was permitted by Slant Operating, LLC and has since transferred to Mobil Producing TX. & N.M. Inc. on the wellbore schedule.

Completion filings report 5 formation tops, including Grayburg, Judkins, San Angelo, Tubb.

Its 3 leases have reported 2.28M barrels of oil and 4.66M mcf of gas since January 1993, last reporting in July 2026. The leases carry 92 wells, so these are lease totals, not this well alone.
