Publication number: 20220389811Abstract: The invention is a method, a system, tools for use by the system, and an interpretation method for injecting and detecting tracers and conducting flow characterizing of a petroleum well. The method describes monitoring of travel time and slip velocity between two/three different phases (oil/water and possibly gas) in the well. The travel time and slip velocity are determined using an injection too for injection of an over pressurized injection of the partitioning tracers each of which would follow certain phase. The tracers are detected by an optical detection probe in the pipe. The slip velocity is obtained from the difference of travel time of two tracers which partition to two different phases.Type: ApplicationFiled: August 12, 2022Publication date: December 8, 2022Applicant: Resman ASInventors: Anton KULYAKHTIN, Christian ANDRESEN, Thomas SPERLE

Patent number: 10865637Abstract: A method, a system, tools for use by the system, and an interpretation method for injecting and detecting tracers and conducting flow characterizing of a petroleum well are provided. The method describes monitoring of travel time and slip velocity between two/three different phases (oil/water and possibly gas) in the well. The travel time and slip velocity are determined using an injection tool for injection of an over pressurized injection, thus simultaneous injection to all phases, of the partitioning tracers each of which would follow certain phase. The tracers are detected by a tracer detector downstream the injector. The slip velocity is obtained from the difference of travel time of two tracers which partition to two different phases.Type: GrantFiled: October 17, 2018Date of Patent: December 15, 2020Assignee: RESMAN ASInventors: Anton Kulyakhtin, Christian Andresen, Thomas Sperle

Patent number: 10100632Abstract: A petroleum well formation pressure meter system includes a petroleum fluid conducting tubing in a borehole through a reservoir rock formation. The tubing includes a blank pipe section forming a blank-pipe-isolated first annulus section isolated by a first and a second packer and an adjacent non-blank pipe section beyond said first packer forming a tubing-communicating petroleum producing second annulus section. The first packer includes a tracer-conducting channel allowing through passage of tracer material from an inlet from a bellows including a fluid tracer in pressure communication with said blank-pipe-isolated annulus section, to an outlet to said tubing-communicating annulus section.Type: GrantFiled: November 29, 2013Date of Patent: October 16, 2018Assignee: RESMAN ASInventors: Fridtjof Nyhavn, Christian Andresen

Patent number: 5808395Abstract: The present invention concerns a motor for generating torques around more than one axis with respect to an object that can be rotated and revolved around only one point. Only one mechanism is necessary to maintain a prescribed position or to produce changes in position around one or more axes (X, Y, or Z).The permanent-magnet excited synchronous machine comprises stator shells (10 & 10.1), multiple-phase windings (11 & 11.1), and a rotor (12) with permanent magnets (13 & 13.1), whereby the annular and spherical surfaces (14) of the rotor are more extensive than the annular and spherical surfaces (15) of the shells.All the spherical surfaces share the same center (M) of curvature, which simultaneously constitutes the origin of the coordinate systems, and the center of rotation. The shaft (17) is supported only at the center of curvature and such as to ensure freedom of motion throughout the reference coordinate system (21).Type: GrantFiled: November 17, 1995Date of Patent: September 15, 1998Assignee: MAN Gutehoffnungshutte AktiengesellschaftInventors: Markus Anders, Egon Christian Andresen, Hans-Jurgen Karcher
