O-Tex Pumping

Bryan Sheffield, who founded Parsley Energy and sold it to Pioneer Natural Resources for $2.56 billion in 2021, serves as Chairman of O-Tex Pumping. The firm is a post-exit venture, not a subsidiary of Parsley, and represents the Sheffield family's reinjection of capital into the Permian Basin's service and midstream sectors. The Sheffield family retains significant holdings across the Permian energy complex.

O-Tex acquires real property water rights, well infrastructure, and transmission pipelines, then supplies water under contract to hydraulic fracturing operations. It earns revenue through take-or-pay or volumetric service agreements with E&P operators, functioning more like a utility than a speculative driller. The model relies on owning or controlling the physical asset base rather than trading water on a spot-market basis.

O-Tex sources water from owned and leased groundwater wells as well as recycling produced water from oil and gas operations. Its infrastructure blends and transfers those water streams to frac sites across the Midland and Delaware sub-basins. The shift toward produced water recycling has become a defining focus, reducing pressure on freshwater aquifers and aligning with operator ESG targets.

O-Tex Pumping is an operating company supplied with patient family capital, not a fee-based investment fund. It holds physical midstream assets directly and generates revenue through field operations, maintenance crews, and water-supply contracts. There is no evidence of external LP commitments, making it structurally distinct from energy-focused private equity funds.

The firm grows by purchasing and consolidating existing water midstream systems from smaller, often family-held operators who lack the capital to scale. It integrates these bolt-on acquisitions into its pipeline network, creating regional density advantages that lower per-barrel water transfer costs. This consolidation mirrors the larger trend of private Permian service companies rolling up to gain market share.

Operations are concentrated in the Permian Basin of West Texas, specifically across Reeves, Loving, and Midland counties. The company's infrastructure spans both the Midland and Delaware sub-basins, targeting high-activity drilling corridors where E&P operators require reliable water supply and disposal solutions. There is no indication of operations outside Texas.

O-Tex has steadily increased its investment in produced water treatment and recycling infrastructure, enabling operators to reuse flowback water rather than disposing of it via saltwater injection wells. This emphasis serves both a commercial purpose — lowering water-sourcing costs — and a regulatory one, as Texas operators face growing scrutiny over induced seismicity linked to deep-well disposal.
