Horton R P NO. 18 #1803 (API 42-311-34117) is a well in Mcmullen County operated by Gtg Operating LLC, completed January 22, 2009 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued December 1, 2008, permitted to 12,000 ft.

It was permitted by Welhausen Operating Company, LP and has since transferred to Gtg Operating LLC on the wellbore schedule.

Completion filings report 2 formation tops, including Carrizo, Olmos.

Its lease has reported 48.7K barrels of oil and 638K mcf of gas since October 1994, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
