Patent number: 11333004Abstract: A piston initiator is used on an assembly having a milling tool and a whipstock for creating a sidetrack in a wellbore. A piston disposed in an uphole position in a bore of the milling tool seals the bore from communicating with the port. A line from the port can communicate pressure to components on the whipstock for initiating their activation. The piston is movable from the uphole position, but is held by a releasable connection configured to release the piston in response to a predetermined force from fluid flow in a downhole direction against an exposed surface area of the piston. An uphole shoulder in the milling tool prevents movement of the piston in an uphole direction so the piston does not stress the releasable connection in response to reverse fluid flow through the milling tool.Type: GrantFiled: June 3, 2020Date of Patent: May 17, 2022Assignee: Weatherford Technology Holdings, LLCInventors: James H. Taylor, Jr., Ronald G. Schmidt

Patent number: 6692711Abstract: Sour natural gas is processed to remove the sulfur compounds and recover C4+/C5+ hydrocarbons by scrubbing the gas with an amine solution to remove most of the sulfur, followed cooling the gas to remove C4+/C5+ hydrocarbons and more sulfur compounds as liquid condensate to produce a gas having less than 20 vppm of total sulfur. The condensate is sent to a fractionator to recover the C4+/C5+ hydrocarbons. The sulfur and hydrocarbon reduced gas is contacted first with zinc oxide and then nickel, to produce a gas having less than 10 vppb of total sulfur which is passed into a synthesis gas generating unit to form a very low sulfur synthesis gas comprising a mixture of H2 and CO. This synthesis gas is useful for hydrocarbon synthesis with increased life of the hydrocarbon synthesis catalyst and greater hydrocarbon production from the hydrocarbon synthesis reactor. Contacting the synthesis gas with zinc oxide further reduces the sulfur content to below 3 vppb.Type: GrantFiled: June 2, 2000Date of Patent: February 17, 2004Assignee: ExxonMobil Research and Engineering CompanyInventors: Dennis G. Alexion, Robert B. Fedich, John C. Wilbur, James H. Taylor, Jr., James P. Glass, Jr., Geoffrey R. Say, Richard P. O'Connor

Patent number: 6103206Abstract: Very low sulfur content hydrocarbon gas is achieved by sequentially contacting the gas first with zinc oxide and then with nickel metal. This has reduced the total sulfur content of natural gas feed for a fluid bed syngas generator to less than 0.1 ppm and has resulted in greater syngas productivity. A zinc oxide guard bed downstream of the syngas generator reduces the total sulfur content of the syngas to less than 10 vppb and preferably less than 5 vppb. This very low sulfur content syngas is used for sulfur sensitive processes, such as hydrocarbon synthesis. The process is especially useful for natural gas which contains H.sub.2 S, COS, mercaptans and other sulfur bearing compounds.Type: GrantFiled: November 6, 1998Date of Patent: August 15, 2000Assignee: Exxon Research and Engineering CoInventors: James H.
