Starr County · Sun North (F-3-D Seg. 3) field · Vertical
Montalvo N. R. #14 (API 42-427-32066) is a plugged well in Starr County, plugged October 11, 1989, last operated by Kerr-Mcgee Oil & Gas Onshore LP.
The RRC has issued one drilling permit, issued October 8, 1985, permitted to 6,200 ft.
It was permitted by Sun Expl. & Prod. CO.-Corpus and has since transferred to Kerr-Mcgee Oil & Gas Onshore LP on the wellbore schedule.
Completion filings report one formation top, including F-3-D, Seg. 3.
Its lease has reported 21.7K barrels of oil and 102K mcf of gas since January 1993, last reporting in February 2020. The lease carries 2 wells, so these are lease totals, not this well alone.
