Patent number: 10240434Abstract: An assembly and method for completion of lateral wellbores is disclosed. The completion assembly includes a junction fitting with main and lateral legs, and a lateral completion string and anchoring device connected to the downhole end of the lateral leg and the uphole end of the junction fitting, respectively. A working string, positioned within the lateral leg, anchoring device, and lateral completion string, includes a setting tool that is removably connected to the anchoring device and a completion tool assembly located within the lateral completion string. The completion assembly is run by the working string into the wellbore. After setting the anchoring device, the working string conveys the completion tool assembly within the lateral completion string for gravel packing, fracturing, frac-packing, acidizing, cementing, perforating, and inflating packers, for example. After wellbore completion, the completion tool assembly is removed through the lateral leg of the junction fitting.Type: GrantFiled: October 24, 2017Date of Patent: March 26, 2019Assignee: HALLIBURTON ENERGY SERVICES INC.Inventors: David J. Steele, Matthew B. Stokes

Patent number: 10145177Abstract: A diverter assembly can include a diverter having a deflection surface, and an annular seal device externally disposed and longitudinally displaceable on the assembly in response to a pressure differential being applied across the device. A well system can include a diverter assembly positioned in a casing, the assembly including a diverter and an annular seal device that seals off an annulus between the assembly and the casing, whereby a pressure differential across the device is reduced by movement of the device on the assembly. A method of sealing off an annulus formed between a diverter assembly and a casing can include positioning an annular seal device on a mandrel, the device being slidingly and sealingly engaged with an outer surface of the mandrel, connecting the mandrel to a diverter, and installing the assembly comprising the device, the mandrel and the diverter in the casing.Type: GrantFiled: January 15, 2014Date of Patent: December 4, 2018Assignee: Halliburton Energy Services, Inc.Inventor: Matthew B.

Patent number: 9399897Abstract: A method of orienting a well tool can include setting down weight on an orienting device, thereby securing in position an engagement member that was previously free to displace circumferentially in the device, and after the securing, engaging the engagement member with an orienting profile. Another method of orienting a well tool can include compressing the orienting device between sections of a tool string, thereby securing in position an engagement member that was previously free to displace circumferentially in the device, the securing step including deforming a structure of the orienting device, and after the securing, engaging the engagement member with an orienting profile.Type: GrantFiled: October 31, 2013Date of Patent: July 26, 2016Assignee: Halliburton Energy Services, Inc.Inventor: Matthew B.
