Abstract
A hydraulic fracturing pump system may include a hydraulic fracturing pump, a gaseous fuel engine configured to drive the hydraulic fracturing pump, a slip device selectively coupling the hydraulic fracturing pump with the gaseous fuel engine, a gear system mechanically coupled to the hydraulic fracturing pump between the hydraulic fracturing pump and the slip device, and a controller. The controller may be configured to cause, in connection with a pressure test for a hydraulic fracturing system that includes the hydraulic fracturing pump system, a slip engagement of the slip device to control an output torque to, and a discharge pressure of, the hydraulic fracturing pump.
