Patent number: 11187064Abstract: A well pumping system can include a rod rotator including a torque transfer device, an outer housing and a rotary actuator. The rotary actuator rotates the torque transfer device and a rod relative to the outer housing. The rod reciprocably displaces longitudinally relative to the outer housing. A method of rotating a rod string can include applying a torque from a torque transfer device to a rod connected to the rod string, the torque being maintained in the rod as the rod displaces relative to an outer housing. The torque transfer device is fully enclosed within the outer housing during the torque applying step. Another well pumping system can include a rod rotator with an outer housing connected between a stuffing box and a blowout preventer. The rod rotator rotates a rod string in a well.Type: GrantFiled: November 20, 2015Date of Patent: November 30, 2021Assignee: Weatherford Technology Holdings, LLCInventors: Benson Thomas, Patricia L.

Patent number: 11156071Abstract: A system and method of wellbore operations that forms notches into a subterranean formation that circumscribes a wellbore prior to fracturing the formation. The notches extend past the hoop stress regime that surrounds the wellbore so that fractures formed by fracturing are oriented in a designated plane. In one example, a fluid jet is used to form the notches, and which is discharged from a nozzle that rotates about a downhole tool. The nozzle is set in a sleeve that is rotatable about the downhole tool, and pressurized fluid is delivered to a plenum disposed on an inner surface of the sleeve. The nozzle is oriented oblique to a radius of the sleeve, so that the fluid being discharged from the nozzle generates a force that rotates the sleeve.Type: GrantFiled: July 18, 2018Date of Patent: October 26, 2021Assignee: SAUDI ARABIAN OIL COMPANYInventors: Fakuen Frank Chang, Brett Bouldin, Ikhsan Nugraha
