The Dallas-based operator has recorded seven drilled wells between 2024 and 2026, targeting the Eagle Ford and Sub-Clarksville formations.

Outlook: Continued South Texas Development
Cytex South Texas is demonstrating continued drilling activity across its Texas acreage. With five Eagle Ford wells, two Sub-Clarksville wells, four drilling rigs involved in its recorded program, and a surface facility registration in Dimmit County, the operator represents an emerging opportunity for oilfield service companies supporting drilling, completions, production equipment and facility operations.
For oilfield service companies, Cytex South Texas is an operator worth watching as its development activity extends across multiple South Texas counties and formations.
