Patent number: 11846151Abstract: A repairing assembly includes a housing, a packer, and a thermal spray assembly. The housing is attached to a wellbore string disposed within a wellbore with casing. The packer is coupled to the housing. The packer is set on a wall of the wellbore to bound a repair zone defined between the packer and an end of the housing opposite the packer. The housing or the packer includes a fluid channel in fluid communication with the wellbore string or an annulus of the wellbore. The thermal spray assembly is coupled to the housing and sprays a damaged section of the casing with a thermal spray to repair the damaged section. The housing flows an inert gas received from the wellbore string or the annulus of the wellbore and through the fluid channel into the repair zone until an oxygen in the repair zone is substantially removed from the repair zone.Type: GrantFiled: March 9, 2021Date of Patent: December 19, 2023Assignee: Saudi Arabian Oil CompanyInventors: Guodong Zhan, Jianhui Xu, Abdulwahab Al-Johar, Bodong Li, Timothy E.

Patent number: 11702741Abstract: A polycrystalline diamond is formed on a substrate to form a polycrystalline diamond compact (PDC) cutter for a tool. The polycrystalline diamond has a cross-sectional dimension of at least 4 millimeters. The substrate includes tungsten carbide. An outer surface of the PDC cutter is at least partially surrounded with at least a single layer of coating by atomic layer deposition. The single layer of coating is configured to protect the PDC cutter from thermal degradation in response to exposure to a temperature greater than 700 degrees Celsius (° C.) and less than about 1050° C.Type: GrantFiled: December 13, 2021Date of Patent: July 18, 2023Assignee: Saudi Arabian Oil CompanyInventors: Jianhui Xu, Guodong Zhan, Abdulwahab Al-Johar

Publication number: 20220065055Abstract: Provided is a system for emplacing an electrically activated lost circulation material within a wellbore. The system may comprise a bottom hole assembly connected to a drill string, with an activation tool that may be provided along the bottom hole assembly. The system may comprise an activation tool with a non-conductive isolation sleeve having an inner bore, electrodes exposed to an outer surface of the isolation sleeve, conductive cables electrically connecting the electrodes to one of an anode terminal and a cathode terminal, and a seat extending into the inner bore. Further provided is a method for plugging a loss zone in a wellbore that may use at least one activation tool. The method may include circulating an electrically activated lost circulation material to the loss zone and delivering electricity from a power source to electrodes of the activation tool to solidify the electrically activated lost circulation material.Type: ApplicationFiled: August 26, 2020Publication date: March 3, 2022Applicant: SAUDI ARABIAN OIL COMPANYInventors: Ammar Alali, Amjad Alshaarawi, Abeer Al-Olayan, Haytham H.
