Calverley 36a #5 (API 42-173-32776) is a well in Glasscock County operated by Laredo Petroleum Inc., completed November 10, 1997.

The RRC has issued 2 drilling permits (amended once) between 1997 and 2019, permitted to 8,300 ft.

It was permitted by Parsley Energy Operations, LLC and has since transferred to Laredo Petroleum Inc. on the wellbore schedule.

Completion filings report 11 formation tops, including U. Spraberry, U. Sprayberry, U. Sprby, L. Spraberry.

Its 3 leases have reported 186K barrels of oil and 250K mcf of gas since November 1997, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
