Patent number: 9422805Abstract: A pressure-sensing device is for use in an underground well. The pressure-sensing device includes a pressure sensor arranged at least to sense whether a pressure in the well is below or above a given limit value, and a signal generator arranged to generate an acoustic signal in a well body in the well in response to a sensed pressure from the pressure sensor exceeding said limit value. A method is for measuring pressure in an underground well. A use of a pressure-sensing device is to monitor the pressure between two spaced-apart barrier elements in an underground well.Type: GrantFiled: June 18, 2013Date of Patent: August 23, 2016Assignee: Innovar Engineering ASInventor: Karluf Hagen

Patent number: 6003607Abstract: Well completion apparatus and associated methods of completing wells provides repositioning of sand control screens and perforating guns without requiring movement of a packer in the wellbore. In a preferred embodiment, a well completion apparatus has a packer, a release apparatus, a telescoping expansion joint, a ball catcher, a sand control screen, and a perforating gun. In another preferred embodiment, a well completion method includes the steps of lowering a packer, release apparatus, telescoping expansion joint, ball catcher, sand control screen, and perforating gun into a well, perforating the wellbore casing, dispensing a sealing ball into the release apparatus, applying pressure to release the release apparatus, and applying pressure to expand the telescoping joint.Type: GrantFiled: September 12, 1996Date of Patent: December 21, 1999Assignee: Halliburton Energy Services, Inc.Inventors: Karluf Hagen, Colby M. Ross, Ralph H. Echols, Andrew Penno

Patent number: 5845711Abstract: The apparatus and method for injecting coiled tubing downhole includes a connector member disposed on the end of the coiled tubing and supporting a downhole tool. A packer member is releasably connected to the connector member. The packer member includes a pack-off element and slips for releasably engaging the outer pipe string through which the coiled tubing is being injected. Seals are provided on the packer member for engaging the outer circumferential surface of the coiled tubing. A fluid passageway extends through the connector member for communicating the packer member with the coiled tubing. Fluid pressure is applied through the flow bore of the coiled tubing. The fluid pressure is applied through the fluid passageway to actuate an actuator member in the packer member to set the pack-off element and slips. Thus, upon actuating the packer member, the annulus formed by the coiled tubing and outer pipe string is closed.Type: GrantFiled: June 2, 1995Date of Patent: December 8, 1998Assignee: Halliburton CompanyInventors: Michael L. Connell, James Craig Tucker, Pat Murphy White, James Robert Longbottom, Paul L. Browne, Michael Dennis Bullock, Karluf Hagen

Patent number: 5823265Abstract: A system for selective production from, and stimulation of, subterranean production zones while improving productivity and enhancing control of the well. Portions of a production tubing string and an internal stimulation/shifter string are assembled and run together as completion segments. Consecutive completion segments, with each segment including packers that surround sleeves and terminate at the upper end in a well control valve, are run into the cased wellbore so that the acid flow ports operated by sleeve valve assemblies are placed proximate the perforations of prospective production zones. The production zones are then stimulated as the stimulation/shifter string is moved progressively outward placing acid at each consecutive zone. The stimulation/shifter string is then removed from the production tubing string, mechanically closing the well control valve assembly by tubing manipulation.Type: GrantFiled: July 19, 1996Date of Patent: October 20, 1998Assignee: Halliburton Energy Services, Inc.Inventors: Robert W. Crow, John C. Gano, Nam Van Le, James R. Longbottom, Karluf Hagen

Patent number: 5564502Abstract: A well control valve assembly prevents flow from or to completion segments further downhole from the well control valve assembly once the stimulation stimulation/shifter string has been removed from the production tubing string. The well control valve assembly features a shaped flapper plate which, when opened, conforms closely to the shape and size of the production tubing string's interior diameter. The flapper plate is biased toward a closed position by a compression spring arrangement that includes an arm which levers the plate upward toward a seating surface. The valve assembly's closure is mechanically induced and is not responsive to a sensed well condition.Type: GrantFiled: January 30, 1995Date of Patent: October 15, 1996Assignee: Halliburton CompanyInventors: Robert W.

Patent number: 5341880Abstract: A sand screen structure used to filter particulate matter from formation fluid entering a well bore is assembled from a plurality of generally tubular filter sections that may be axially snapped together in a manner facilitating the simultaneous interconnection of circumferentially spaced series of axially extending shunt tubes secured to and passing internally through each of the filter sections. By utilizing snap-fit interconnections between the filter sections, instead of conventional threaded connections, the assembly of the overall sand screen structure is made substantially easier and quicker, and the lengths of the blank, nonfiltering portions of the sand screen structure between its individual filter sections are substantially reduced. In an alternate embodiment of the sand screen structure the shunt tubes are secured within external side surface recesses of the filter section bodies.Type: GrantFiled: July 16, 1993Date of Patent: August 30, 1994Assignee: Halliburton CompanyInventors: Egil Thorstensen, Karluf Hagen
