Publication number: 20200190942Abstract: A flow control apparatus comprising: a housing, a housing passage disposed within the housing, a subterranean formation flow communicator for effecting flow communication between the subterranean formation and the housing passage, a flow control member, displaceable, relative to the subterranean formation flow communicator, for effecting at least opening of the subterranean formation flow communicator There is further provided a first actuation system for actuating displacement of the flow control member relative to the subterranean flow communicator. There is also provided a second actuation system for actuating displacement of the flow control member relative to the subterranean flow communicator. Relative to the central longitudinal axis of the housing passage, the first actuation system is angularly spaced from the second actuation system.Type: ApplicationFiled: August 30, 2019Publication date: June 18, 2020Inventors: Michael WERRIES, Lyle LAUN, John RAVENSBERGEN, Ramin TAJALLIPOUR, Brock GILLIS, Roman VAKULIN

Publication number: 20190360301Abstract: A rupture disc assembly and a float tool incorporating the rupture disc assembly is disclosed. The rupture disc assembly may include a rupture disc assembly comprising a rupture disc, an upper tubular portion and a lower tubular portion, and a securing mechanism for holding the rupture disc between the upper and lower tubular portions. A float tool for creating a buoyant chamber in a casing string may include the rupture disc assembly and a sealing device for sealing the lower end of the casing string, the buoyant, sealed chamber may be created there between. In operation, applied fluid pressure causes the rupture disc to move downward. The rupture disc may be shattered by contact with a surface on the lower tubular portion. Full casing internal diameter may be restored in the region where the rupture disc formerly sealed the casing.Type: ApplicationFiled: August 7, 2019Publication date: November 28, 2019Inventors: Donald GETZLAF, Marty STROMQUIST, John RAVENSBERGEN, David DEVLIN, Douglas BRADEN, Travis HARRIS

Patent number: 10487626Abstract: A fracturing valve comprising a tubular mandrel having a through bore continuous with a tubing string, and a frac window through the side of the tubular mandrel. An outer sleeve is radially disposed around the tubular mandrel. The outer sleeve includes a sleeve port in a sidewall. The tubular mandrel slides relative to the sleeve by application and release of set down weight on a coiled tubing string. When the valve is closed, there is no fluid communication from the tubing string out of the frac window. When the valve is open, fluid communication from the tubing string is enabled. The valve may be installed in a downhole tool having a perforation device. The tool string can be used with one sealing element as the tool is pulled up the hole isolating lower perforations, or with two sealing elements to allow pin-point treatments isolating perforations both up and downhole.Type: GrantFiled: February 2, 2018Date of Patent: November 26, 2019Assignee: NCS Multistage, Inc.Inventors: Donald Getzlaf, John Ravensbergen, Douglas James Brunskill, Shawn Leggett

Patent number: 10208564Abstract: A rupture assembly that may be employed in the oilfield industry facilitates the deployment of a tubing string in a well. The rupture assembly may be installed at the bottom of the tubing string for the purpose of trapping air in a lateral section of the tubing, between the rupture assembly and an upper sealing assembly. As a result, the buoyant force in the lateral section reduces the drag encountered while running the tubing through the casing, thereby significantly reducing rig time, or permitting operations where none were possible previously. Once at landing depth, surface pressure may be added to burst and remove the seal and rupture assemblies.Type: GrantFiled: October 5, 2016Date of Patent: February 19, 2019Assignee: NCS MULTISTAGE INC.Inventors: John Ravensbergen, Juan Montero
