0%Pioneer Energy is supplying field gas conditioning equipment to support Rolfson Oil's Tri-Fueling approach for hydraulic fracturing operations. The equipment includes mechanical refrigeration units and auxiliary skids that remove water and heavy hydrocarbons from field gas to provide consistent fuel. Rolfson Oil, described as the largest provider of frac fueling services in the US, uses Pioneer's technology as part of its Tri-Fueling system, which distributes conditioned field gas to dual fuel and natural gas powered equipment. The approach aims to reduce frac fuel costs and improve operational efficiency. Pioneer Energy's Vice President Joseph Palaia said increased field gas utilisation presents an immediate pathway to reduce costs. Both companies believe field gas utilisation represents an important evolution in frac fleet fueling as operators prioritise cost reduction and emissions performance.
Trive capital invests in Rolfson oil. Subsequent to Trive's investment, Rolfson acquired Flint Logistics Group, an Oklahoma City-based provider of fuel, oils, and lubricants. 32 minutes ago
