In-house engineering and testing ensure grain consistency and performance under pressure and that proppants meet or exceed ISO 13503-2 and API RP 19C specifications for particle distribution, roundness and sphericity, turbidity, acid solubility and crush resistance. An extensive rail fleet, 50-plus transloads and a network of regional and in-basin mines provide extensive access to sand for U.S. Silica customers. Additionally, SandBox Logistics, a wholly owned subsidiary of U.S. Silica, provides a new approach to proppant storage, handling and wellsite delivery. With a logistics process and containerization solu- tion, "SandBox can lower costs, increase operational efficiency and drastically reduce the health and safety impact of silica dust on any hydraulic fracturing job- site," according to the company. Weir Oil & Gas Weir Oil & Gas provides well service and stimula- tion pumps, flow control products and replacement expendable parts from brands including SPM, Mesa and Novatech. Pressure control includes brands such as Seaboard, which provides wellheads, valves and fracture trees, and Mathena, which delivers drilling mud-gas separation equipment including chokes, separators and environmental containment equip- ment. The company offers mechanical and rotating equipment repairs and upgrades, oilfield and drilling equipment repair and certification, asset manage- ment and field services. In May 2018 Weir released Weir Edge, its newly branded aftermarket services program. Weir Edge is designed to extend equipment life and reduce total cost of ownership, according to a press release.
