Castillo Deep GU #5 (API 42-215-32751) is a well in Hidalgo County operated by Merit Energy Company, completed May 15, 2000 and listed as swr-10-well on the RRC schedule, shut in September 1, 2017.

The RRC has issued one drilling permit (amended once), issued March 24, 2000, permitted to 12,812 ft.

It was permitted by Coastal Oil & Gas Corporation and has since transferred to Merit Energy Company on the wellbore schedule.

Completion filings report 7 formation tops, including Sullivan Sand, J-1 Sand, K-1 Sand, L Sd..

Its 4 leases have reported 6.79K barrels of oil and 1.59M mcf of gas since May 2000, with no volume in the three years through April 2026. The leases carry 4 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
