Patent number: 11680454Abstract: A method of plugging a well extending into a formation to facilitate temporary or permanent abandonment of the well. The method comprises conveying a plug placement and verification tool (PPVT) through the well, to a plug formation location, the PPVT comprising a stinger for delivering a plugging material into the well, an expandable packer disposed at one end of the stinger and a pressure sensor disposed below the expandable packer, and operating the expandable packer to form a seal in the well above the pressure sensor. The method further comprises delivering a plugging material from the stinger into a region of the well above the expandable packer, thereby forming a plug in the well, and thereafter creating a pressure change above the plug and verifying the integrity of the plug using the pressure sensor.Type: GrantFiled: December 10, 2021Date of Patent: June 20, 2023Assignee: EQUINOR ENERGY ASInventors: Gjermund Grimsbo, Pål Viggo Hemmingsen, Halvor Kjørholt, Gisle Stjern

Patent number: 10865619Abstract: A method of plugging a well in a plug and abandonment procedure includes providing a tubing in a wellbore, in a location for a well plug, the tubing is provided with an internal cable section placed inside of the tubing, and forming a plug in the well in said location for the well plug across the width of the tubing and a surrounding wellbore annulus to create a permanent barrier without pulling the tubing from the wellbore. The step of forming the plug includes substantially removing the internal cable section inside the tubing and forming a fluid-tight seal in the tubing where the internal cable section has been removed, for separating, on either side of the seal, first and second fluid volumes of the tubing.Type: GrantFiled: December 12, 2018Date of Patent: December 15, 2020Assignee: STATOIL PETROLEUM ASInventors: Pål Viggo Hemmingsen, Gjermund Grimsbo

Patent number: 10392885Abstract: A method of plugging a well extending into a formation to facilitate temporary or permanent abandonment of the well. The method comprises conveying in one trip, a plug assembly and one or more explosive charges through the well together with a structure for providing wet sealant. The plug assembly comprises a foundation plug for supporting the wet sealant. The plug assembly is set beneath a plug formation location, prior to providing the wet sealant. The method also comprises providing the wet sealant to the plug formation location via the structure, so as to submerge the one or more explosive charges in the wet sealant, and then detonating the one or more explosive charges in the wet sealant at the plug formation location to cut through a tubular or tubulars of the well and into the formation.Type: GrantFiled: November 22, 2017Date of Patent: August 27, 2019Assignee: STATOIL PETROLEUM ASInventors: Gisle Stjern, Gjermund Grimsbo, Halvor Kjørholt, Pål Viggo Hemmingsen

Patent number: 9702745Abstract: A method and apparatus for determining multiphase flow characteristics inside production equipment containing at least two fluids. A pulse of heat from a heat source adjacent to the production equipment is provided, and a thermal response to the pulse is measured at each of a plurality of temperature sensors located adjacent to the production equipment. The thermal response measurement includes a time constant obtained from a measured decline in the temperature after the pulse of heat has been provided.
