Patent number: 11624250Abstract: An electric motor-actuated tractor (e-Tractor) apparatus and method for use in downhole operations. The apparatus includes a power subassembly, a tractor subassembly and one or more gripper subassemblies and can be: run in a single or multiple e-Tractor configuration; run in either intermittent-motion tractoring mode or continuous-motion tractoring mode with the ability to switch between the two modes; used to generate both distal and proximal longitudinal forces to move the run-in string into or out of the wellbore; repeatedly activated and deactivated without run-in string manipulation or hydraulic pressure; and combined with tensiometer and other sensor package options to provide real-time data to the surface to optimize tractoring operations. The apparatus and method are well-suited for application in an c-coil conveyed workover or completion system, and for use in extended reach laterals in horizontal wells.Type: GrantFiled: June 4, 2021Date of Patent: April 11, 2023Assignee: Coiled Tubing Specialties, LLCInventors: Bruce L.

Publication number: 20190153841Abstract: A method for avoiding a frac hit during a formation stimulation operation. The method includes providing a child wellbore within a hydrocarbon-producing field. The method also includes identifying a parent wellbore within the hydrocarbon-producing field. The method also includes conveying a hydraulic jetting assembly into the child wellbore on a working string. The method additionally includes setting a whipstock in the wellbore at a first casing exit location. The method then includes injecting hydraulic jetting fluid through a jetting hose and connected jetting nozzle while advancing the nozzle through against a face of the whipstock, and through a first window. The nozzle advances into the surrounding rock matrix, thereby forming a lateral borehole that extends away from the wellbore. The method also includes controlling (i) a distance of the lateral borehole from the child wellbore, (ii) a direction of the lateral borehole from the child wellbore, or (iii) both prior to hydraulic fracturing.Type: ApplicationFiled: January 11, 2019Publication date: May 23, 2019Inventors: Bruce L.

Patent number: 8393389Abstract: A running tool includes subassemblies which release the running tool from the liner hanger in response to application of alternating tensile and compressive forces after application of left-hand torque. A running tool includes subassemblies which set the liner hanger in response to left-hand torque followed by increased pressure, and in response to increased pressure without prior left-hand torque being applied. A running tool includes threaded connections, without torque transmitted through the running tool being transmitted by the threaded connections. A method of setting a liner hanger includes applying a compressive force to the running tool; then applying left-hand torque to the running tool; and then applying a tensile force to the running tool. A method of releasing a liner hanger includes applying left-hand torque to the running tool; and then releasing the running tool from the liner hanger by applying a tensile force to the running tool.Type: GrantFiled: April 20, 2007Date of Patent: March 12, 2013Assignee: Halliburton Evergy Services, Inc.Inventors: David P.
