Abstract: A process for the production of sustainable aviation fuel (SAF) with low carbon intensity. The jet fuel is produced from the reaction of hydrogen from the electrolysis of water with captured carbon dioxide. The hydrogen and carbon dioxide are reacted to product a stream comprising carbon monoxide. Hydrogen and carbon monoxide are reacted to produce n-alkanes. Alkanes are hydroisomerized to produce sustainable aviation fuel with low carbon intensity.

Abstract: Production of fuels from low carbon electricity and from carbon dioxide by the use of a solid oxide electrolysis cell (SOEC) and Fischer-Tropsch is shown. Fischer-Tropsch is an exothermic reaction that can be used to produce steam. Steam produced from the Liquid Fuel Production (LFP) reactor system, where the Fischer-Tropsch reaction occurs, is used as feed to the SOEC. The higher temperature steam improves the efficiency of the overall electrolysis system. The integration of the LFP steam improves the efficiency of the electrolysis because the heat of vaporization for the liquid water does not have to be supplied by the electrolyzer.

Abstract: A technique facilitates the anchoring and use of a downhole tool. The technique may be utilized with operations in which fluid is pumped or otherwise flowed through a tubular to the downhole tool. The operations are performed after the downhole tool has been fixed relative to the wellbore and while the tubular remains connected to the downhole tool. In some operations, the downhole tool is manipulated from the surface via the tubular to control placement of the fluid flowing down through the tubular.

Abstract: An assembly for inclusion in a tool string conveyed via coiled tubing within a wellbore. The assembly includes a mandrel having a passage for receiving fluid via the coiled tubing. The assembly further includes a packer disposed about the mandrel and expandable into sealing contact with a wall of the wellbore in response to receiving the fluid from the passage. The assembly also includes a flow control device controlling flow of the fluid from the passage into the packer. The flow control device includes a degradable material that is reactive to the fluid.

Abstract: A coiled tubing connection system is used in a well. A connector having an engagement end is used to couple a wellbore device to the end of a coiled tubing. The connector is spoolable, and the engagement end comprises engagement features that facilitate formation of a connection that is dependable and less susceptible to separation.

Abstract: The current application discloses coiled tubing assemblies and methods of connecting coiled tubing with downhole devices. In an exemplary embodiment, the assembly comprises a coiled tubing, a downhole device for performing an operation in a subterranean wellbore, a connector that mechanically connects the coiled tubing to the downhole device; and a sealing device that seals the connection between the coiled tubing and the connector. The sealing device is substantially free of axial tensions caused by a weight of the downhole device.

Abstract: A method for use within a subterranean formation penetrated by a wellbore includes introducing a thixotropic agent into the well and introducing a cement slurry into the well. The method includes forming a thixotropic cement slurry downhole, including mixing the cement slurry and the thixotropic agent downhole.

Abstract: A technique provides an orientation system combined with downhole equipment used in a well. An orientation device is mounted in the downhole equipment, e.g. a bottom hole assembly, for actuation during angular displacement of the downhole equipment. A sensor is mounted to cooperate with the orientation device in detecting the angular displacement.

Abstract: Apparatus and methods for selectively and safely reversing flow in coiled tubing used for wellbore cleanouts are disclosed. One apparatus includes a section of coiled tubing having a main flow channel, at least two flow-preventing valves in the section of coiled tubing, each adapted to close the main flow channel upon attempted flow reversal; and at least one actuator adapted to deter closing of the flow-preventing valves.
