Patent number: 12215035Abstract: Lithium recovery processes are described using concentration and conversion techniques. A vaporizer or membrane can be used to concentrate lithium and precipitate impurities. A conversion process can be used to replace anions in lithium bearing streams by adding a second anion and precipitating lithium in a salt with the second anion. Rotary separation can be used to separate the precipitated lithium salt.Type: GrantFiled: December 1, 2022Date of Patent: February 4, 2025Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Dominic Perroni, Gary W.

Publication number: 20230392592Abstract: Certain embodiments of the present disclosure generally relate to pumps for conveying fluid at a wellsite. More specifically, some embodiments relate to pumps, such as fracturing or other stimulation pumps, instrumented with sensors to measure or estimate pump parameters. In some instances, pump sensors are used to detect wear or failure or assess remaining useful life of pump components. The sensors can also or instead be used to assess, and in some cases optimize, pump performance. Various additional systems, devices, and methods are also disclosed.Type: ApplicationFiled: October 25, 2021Publication date: December 7, 2023Inventors: Rod W.

Publication number: 20180100358Abstract: A technique facilitates positively centering a well component, e.g. a downhole tool and/or coiled tubing, inside a pressure barrier, e.g. a riser. A centering device is positioned along the pressure barrier to move the well component toward a center of the pressure barrier. The centering device has a movable member, e.g. a plurality of movable members, selectively shiftable between a radially outward position and a radially inward position within the pressure barrier component. The well component is moved toward the center of the pressure barrier during shifting of the movable member(s) toward the radially inward position.Type: ApplicationFiled: October 10, 2016Publication date: April 12, 2018Inventor: Rod W. Shampine

Patent number: 7810555Abstract: The invention generally relates to an apparatus and/or a method for moving an round flexible member into and out of a well bore, and particularly, to an injector with two or more gripping members which bind the outer surface of the round flexible member; two or more actuators which cause the gripping members to bind or release the round flexible member; and at least one reciprocator for translating a gripping member to move the round flexible member, or for repositioning the gripping member. A method of translating a round flexible member is also provided which includes the steps of binding the outer surface of a round flexible member with at least one gripping members by engagement with an actuator, and translating a gripping member by reciprocator to move the round flexible member.Type: GrantFiled: February 12, 2007Date of Patent: October 12, 2010Assignee: Schlumberger Technology CorporationInventors: Rod W. Shampine, Lawrence J Leising, Yarom Polsky, Hubertus V. Thomeer, Sarmad Adnan

Patent number: 6273188Abstract: A trailer (10) has a dropped center section (12) defining a well (16) for a coiled tubing reel (22). A mast (30) has a pair of posts (34) on which a carriage (32) is mounted for movement along posts (34). An injector head (36) is supported on carriage (32) for pivotal movement in a vertical plane relative to mast (30) and for horizontal movement along a tubular support member (38) of carriage (32) relative to mast (30). Mast (30) is pivotally mounted on the rear end of trailer (10) for movement away from trailer (10) for positioning over a wellhead. In a stored position, mast posts (34) fit alongside the ends of reel (22) so that to the total height of the stored coiled tubing rig is no more than 13½ feet for over the road travel.Type: GrantFiled: December 3, 1999Date of Patent: August 14, 2001Assignee: Schlumberger Technology CorporationInventors: Terry L.

Patent number: 5887018Abstract: An electromagnetic levitator is disclosed, comprising: a plurality of longitudinal sections formed from a conducting material and arranged around a longitudinal axis. The longitudinal sections are connected to a power source such that when the levitator is in operation, current flowing through adjacent longitudinal sections creates opposing magnetic fields. The levitator has first and second ends defining a levitation zone therebetween. When alternating current is passed through the conductors, a levitation tunnel is formed in the levitation zone, with the levitation tunnel having zero magnetic flux density along its center and non-zero magnetic flux density at all other points.Type: GrantFiled: July 9, 1996Date of Patent: March 23, 1999Assignee: WM.
