History

PenRob Well Service, based in Jonesville, TX, primarily provides dirt construction, pipeline construction and maintenance, roustabout services, and well workover services to support the Haynesville and Cotton Valley oil and gas activity in the East Texas and North Louisiana areas. Jonesville is located off I-20 near the Texas/Louisiana border.

Select Energy Services acquired PenRob Well Service on 6/30/09. PenRob was founded in January 2005 in response to the growing pipeline construction need in the region. Since then, the service offerings have expanded with the market needs.
