Patent number: 11060399Abstract: A drilling operation can be optimized based on feedback provided by density sensors in a flow pipe. The drilling can be in a wellbore penetrating a subterranean formation while circulating a drilling fluid. The sensor can be used to detect an actual density of cuttings in the drilling fluid and within a region of the flow pipe. A modelled density of the cuttings can be calculated for the region based on an initial model. The initial model can be based on a comparison of an equivalent circulating density profile to a fracture gradient of the subterranean formation. Based on a comparison of the actual density of the cuttings to the modelled density of the cuttings, the initial model can be adjusted to generate an adjusted model. At least one operational parameter of the drilling can be changed based on the adjusted model.Type: GrantFiled: November 29, 2017Date of Patent: July 13, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Dale E.

Patent number: 10935011Abstract: A pump system/method configured to provide substantially constant flow of concrete, cement, or other material is disclosed. The system integrates a trapezoidal cutting ring and spectacle plate in conjunction with lofted transitional interfaces to the mechanical pump cylinder rams and output ejection port to ensure that pressurized discharge concrete material is not allowed to be relaxed nor backflow into the material sourcing hopper. The trapezoidal cutting ring is configured to completely seal off the trapezoidal spectacle ports as it smoothly transitions between the mechanical pump input ports during cycle changes thus generating a more uniform output flow of concrete while eliminating hopper backflow and hydraulic fluid shock. A control system is configured to coordinate operation of the hydraulic pump cylinder rams and cutting ring to ensure that output ejection port pressure and material flow is maintained at a relatively constant level throughout all portions of the pumping cycle.Type: GrantFiled: January 8, 2020Date of Patent: March 2, 2021Inventor: Francis Wayne Priddy
