Patent number: 10301904Abstract: A method is for isolation of a permeable zone in a subterranean well, wherein the well is provided with a pipe body. The method comprises lowering a perforation tool into the pipe body; forming holes in the pipe body along a longitudinal section; pumping a flushing fluid out through outlets in a flushing tool, into the pipe body and further out into an annulus; pumping a fluidized plugging material out through the flushing tool, into the pipe body and further out into the annulus; placing the fluidized plugging material along the longitudinal section so as to form a plug across the cross section of the well, whereby the plug fills the pipe body and the annulus; wherein at least one outlet in the flushing tool is angled non-perpendicularly relative to a longitudinal axis of the flushing tool, whereby a corresponding discharge jet also will be non-perpendicular to the longitudinal axis.Type: GrantFiled: August 26, 2014Date of Patent: May 28, 2019Assignee: Hydra Systems ASInventors: Arne Gunnar Larsen, Roy Inge Jensen, Patrick Andersen, Erlend Engelsgjerd, Markus Iuell, Arnt Olav Dahl, Arnold Østvold, Morten Myhre

Patent number: 10180043Abstract: A method is for establishment of a new well path from a well. The method comprises disposing and anchoring a plug base in a casing in the well; lowering a perforation tool into the casing; forming holes in the casing along a longitudinal section; pumping a flushing fluid out through outlets in a flushing tool and into the casing and further out into an annulus; pumping a fluidized plugging material out through the flushing tool and into the casing and further out into the annulus; placing the fluidized plugging material along the longitudinal section so as to form a plug across a cross section of the well; wherein the outlets in the flushing tool are angled non-perpendicularly relative to a longitudinal axis of the flushing tool.Type: GrantFiled: August 12, 2014Date of Patent: January 15, 2019Assignee: Hydra Systems ASInventors: Morten Myhre, Arne Gunnar Larsen, Roy Inge Jensen, Patrick Andersen, Arnt Olav Dahl, Erlend Engelsgjerd, Markus Iuell, Arnold Østvold

Publication number: 20180187518Abstract: A method of plugging and abandoning a well includes: lowering a perforation tool into a pipe string onto a longitudinal section; forming perforations along the longitudinal section; with a flushing tool attached to a work string and lowered onto the longitudinal section, pumping flushing fluid through the work string, out through at least one flushing outlet in the flushing tool, into the pipe string and into said annulus via the perforations, wherein an outlet axis of said flushing outlet is non-perpendicular to a longitudinal axis of the flushing tool; pumping a fluidized plugging material through the work string and into the pipe string at the longitudinal section; placing the fluidized plugging material in the pipe string along the longitudinal section, thereby also placing the fluidized plugging material in said annulus via the perforations; pulling the work string out of the well; and abandoning the well.Type: ApplicationFiled: June 1, 2016Publication date: July 5, 2018Applicant: Hydra Systems ASInventors: Morten Myhre, Arne Gunnar Larsen, Roy Inge Jensen, Patrick Andersen, Arnold Østvold, Arnt Olav Dahl

Patent number: 9909378Abstract: A method is for cutting of at least one line disposed along a pipe string in a well. The method includes (A), using a cutting tool for selective cutting activation and provided with at least one cut-forming means for cutting in a radial direction outward from the cutting tool; and (B) lowering the cutting tool to a longitudinal section where the cutting is to be carried out. In (A), a cutting tool is used for controlled cutting in a peripheral direction and distributed in an axial direction relative to the cutting tool. The method further includes (C), activating the cutting tool and cutting, in the radial direction through and past the wall of the pipe string, at least one peripherally extending hole collectively covering the entire circumference of the pipe string, and also distributing the hole in the axial direction.Type: GrantFiled: February 5, 2014Date of Patent: March 6, 2018Assignee: Hydra Systems ASInventors: Morten Myhre, Arne Gunnar Larsen, Roy Inge Jensen, Patrick Andersen, Erlend Engelsgjerd, Markus Iuell, Arnold Ostvold, Arnt Olav Dahl

Patent number: 9695671Abstract: A method is for plugging a well wherein the well, at least along a longitudinal section to be plugged, is provided with one or more pipe bodies forming a radial boundary between the well and a surrounding formation. The method includes (D), lowering a flow-through string into the well and, by the flow-through string, supplying a fluidized plugging material along the longitudinal section in the well, and at least within the innermost of said one or more pipe bodies in the well. The method, before step (D), also comprises (A), lowering one or more explosive charges into the well and onto the longitudinal section to be plugged, and detonating one or more of said explosive charges so as to extend the diameter of one or more of said pipe bodies at one or more places along the longitudinal section to be plugged. A system is for plugging a well.Type: GrantFiled: March 12, 2014Date of Patent: July 4, 2017Assignee: Hydra PandA ASInventors: Morten Myhre, Arne Gunnar Larsen, Roy Inge Jensen, Patrick Andersen, Erlend Engelsgjerd, Markus Iuell, Arnt Olav Dahl, Arnold Ostvold

Patent number: 9416636Abstract: A hydraulic cutting tool, a system, and a method are for hydraulic cutting through a pipe wall of a pipe body. For this purpose, the cutting tool is provided with at least one cutting section comprising at least one fluid discharge body. Each such fluid discharge body comprises at least two outwardly directed discharge openings having non-parallel discharge directions directed at a common intersection point located outside the fluid discharge body. The cutting is carried out by means of an abrasive fluid being supplied, via a flow-through pipe string, to the at least one fluid discharge body from a remote location. Thereby, abrasive cutting jets will discharge at high velocity from the fluid discharge body so as to meet and disperse in the intersection point, thus weakening the further cutting ability of the cutting jets.Type: GrantFiled: April 7, 2014Date of Patent: August 16, 2016Assignee: Well Technology ASInventors: Morten Myhre, Arne Gunnar Larsen, Roy Inge Jensen, Patrick Andersen, Erlend Engelsgjerd, Markus Iuell, Arnt Olav Dahl, Nils Rune Haga, Arnold Ostvold
