What Mountain Supply & Service, L.L.C. does

Mountain Supply & Service, L.L.C. is a privately held oilfield supply and service company founded in 2009 by two East Texas families and headquartered in Longview, Texas. The company provides completion chemicals (friction reducers, gels, lubricants, biocides, scavengers/inhibitors), flow iron and consumables, proprietary injection systems for real-time polymer hydration, water treatment and filtration services, and pressure testing through its Mountain Pressure Testing subsidiary, serving oil and gas operators and coiled tubing service companies across the Marcellus, Bakken, Permian, and Niobrara basins.

The company's core technology centers on proprietary completion chemical formulations — including the FR-900 friction reducer (rapid hydration, effective at temperatures up to 300°F), the GEL series for high-viscosity sweeps, and lubricant blends for torque and drag reduction — paired with automated Injection Systems that hydrate polymers in real time without traditional blending units. It also operates surface filtration plants rated 16-62 barrels per minute, application-specific water treatment programs with biological and chemical analysis, and the IronWorks software platform for real-time flow line equipment tracking. Mountain Pressure Testing is pursuing ISO 9001 certification and provides Level I/II nondestructive pressure testing with ASNT-certified technicians.

Revenue is generated through unit pricing on chemical and supply products sold in 5 gallon pails and totes, complemented by professional-services revenue from water treatment programs and filtration plants operated by trained technicians. Distribution is exclusively direct-to-customer via a field sales organization organized into Northern (WV/OH), Central (ND/CO), and Southern (TX) divisions with seven stocking locations, supplemented by conference presence at SPE/ICoTA events and customer case-study content marketing. The company maintains wholly owned subsidiaries for pressure testing (Mountain Pressure Testing, L.L.C.), equipment tracking software (IronWorks), and water treatment services, and operates with 101-250 employees under family ownership with no disclosed external institutional investment.
