Publication number: 20230175690Abstract: A system for a spark plume generator system for igniting flammable gases at a drilling rig includes a support disposed within a fireproof housing proximate to the drilling rig. A grinder is mounted on the support. The grinder includes a rotatable grinder axle with an abrasive grinder surface and an igniter mounted on the support so as to cooperatively contact the grinder. The igniter includes an igniter surface that creates sparks when abraded. The fireproof housing includes an opening. Upon rotation of the grinder axle, the grinder surface abrades the igniter surface to create sparks. The support is positioned within the fireproof housing so that sparks created by the igniter surface exit the fireproof housing through the opening. The fireproof housing is positioned such that the opening is facing the drilling rig and sparks exiting the opening will ignite any flammable gases at the drilling rig.Type: ApplicationFiled: December 6, 2021Publication date: June 8, 2023Applicant: Aramco Overseas Company UK LtdInventor: Richard Mark Pye

Patent number: 11572752Abstract: A method of deploying a flexible cable in a wellbore includes carrying, by a tubular assembly, a cable spool cartridge into the wellbore. The cable spool cartridge is attached to an exterior of the tubular assembly and contains the flexible cable. A first end of the flexible cable is attached to a buoyancy device, and the buoyancy device is releasably attached to the cable spool cartridge. A fluid is flowed by the tubular assembly in a downhole direction through an interior of the tubular assembly and in an uphole direction within an annulus at least partially defined by the exterior of the tubular assembly. The fluid has a greater density than the buoyancy device. The buoyancy device is released by the cable spool cartridge, and the buoyancy device is configured to travel after release in the uphole direction with the fluid and thereby pull the flexible cable from the cable spool cartridge and into the annulus.Type: GrantFiled: February 24, 2021Date of Patent: February 7, 2023Assignee: Saudi Arabian Oil CompanyInventors: Timothy E.
