Patent number: 11970925Abstract: A method, related device and system for lifting a reservoir fluid in an oil and gas well involves allowing the reservoir fluid to flow in an axial uphole direction through an internal flow path of a production tubing disposed in the well. The internal flow path includes a Venturi profile configured to flash out a free gas phase from the reservoir fluid as the reservoir fluid flows in the axial uphole direction through the Venturi profile, such that the reservoir fluid comprises the free gas phase and a liquid phase. The internal flow path also includes a diffusion profile disposed above the Venturi profile and configured to condense the free gas phase into the liquid phase as the reservoir fluid flows in axial uphole direction through the diffusion profile.Type: GrantFiled: September 28, 2021Date of Patent: April 30, 2024Assignee: Tier 1 Energy Solutions, Inc.Inventors: Jeff King, Jeffrey Golinowski

Publication number: 20240011366Abstract: A packer assembly includes (a) a mandrel bearing an expandable packer element, the mandrel having a ratchet section, a lower collet retaining shoulder, and defining a plurality of longitudinal slots; (b) a push sleeve connected to a ratchet ring by at least one shear pin, wherein the ratchet ring is disposed between push sleeve and the mandrel and engages the mandrel ratchet section; (c) a shift sleeve comprising an inner shift sleeve slidingly disposed within the mandrel and having a lower collet, the inner shift sleeve defining a profile for engaging a shifting tool, and an outer shift sleeve slidingly around the mandrel and connected to the inner shift sleeve with a plurality of bolts, wherein each bolt passes through a longitudinal slot defined by the mandrel; (d) wherein the shift sleeve and push sleeve is moveable between a running position and a released position. Also disclosed are methods of using a packer actuated by a sliding sleeve.Type: ApplicationFiled: July 6, 2023Publication date: January 11, 2024Inventors: Ronald Scott Alders, Jeffrey Golinowski, Daniel P.

Patent number: 11808103Abstract: A swellable packer assembly includes a mandrel, a base pipe disposed within the mandrel, a swellable seal element retained externally on the mandrel, and a shearable member that releasably secures the base pipe to the mandrel. In use, the base pipe forms part of a downhole tubing string in a wellbore. The seal element is swelled with a swelling fluid to seal between an outer wall of the mandrel and a wellbore wall. The shearable member is allowed to shear so that the injection tubing string including the base pipe may move axially within to the wellbore, while the seal element and the mandrel remain stationary relative to wellbore, with the seal element in contact with the wellbore wall. The assembly may help to avoid distortion of and damage to the seal element that may otherwise occur due to thermal expansion and contraction of the downhole tubing string.Type: GrantFiled: January 28, 2021Date of Patent: November 7, 2023Inventors: Ronald Scott Alders, Jeffrey Golinowski, Daniel P Lupien

Patent number: 11802445Abstract: A cable head for attaching a wireline to a downhole tool includes an upper tubular member and a lower tubular member removably attached by a threaded connection. The cable head includes a pack-off assembly disposed within the upper tubular member. The pack-off assembly includes a deformable pack-off element comprising an outer sidewall for sealing against an inner sidewall of the upper tubular member, and an inner sidewall for sealing around the wireline. The pack-off assembly includes a biasing means axially in line with the deformable pack-off element. The pack-off element and the biasing means are axially compressed between an internal shoulder of the upper tubular member and the lower tubular member when the upper and lower tubular members are removably attached by the threaded connection, to enhance the seal of the tubular pack-off element with the inner sidewall of the upper tubular member, and with the wireline.Type: GrantFiled: May 12, 2022Date of Patent: October 31, 2023Assignee: Tier 1 Energy Solutions, Inc.Inventor: Jeffrey Golinowski

Patent number: 11761316Abstract: A steam diverter apparatus for forming part of a downhole tubing string is provided. The apparatus may be used in a SAGD operation to control flow of steam into a formation. The apparatus includes a tubular housing defining steam-admitting ports, and containing a moveable shift sleeve. The apparatus is modifiable for use with position shifting tools of different outer diameters by interchanging first and second sets of the shift sleeve and insert rings having different minimum inner diameters within the housing. The open flow area of the apparatus is modifiable by plugs that block the ports and are removably attached to the housing. The plug, the shift sleeve, or both of them may be made of a dissolvable material, so that they can be dissolved by a chemical solution injected into the tubing string, for the purpose of controlling steam flow through the ports.Type: GrantFiled: January 22, 2021Date of Patent: September 19, 2023Inventors: Ronald Scott Alders, Jeffrey Golinowski, Daniel P.

Patent number: 9739112Abstract: A downhole packer includes a first locking member positioned at least partially around an outer surface of an oilfield tubular. The first locking member includes an inner surface that engages the outer surface of the oilfield tubular, and a tapered outer surface. A drive ring is positioned at least partially around the first locking member. The drive ring includes a reverse-tapered inner surface that engages the tapered outer surface of the first locking member. A first cap is movably coupled with the drive ring, disposed at least partially around the first locking member, and axially engaging the first locking member. Moving at least one of the first cap and the drive ring toward the other causes the drive ring to apply a radially-inward force on the first locking member, causing the first locking member to be secured to the tubular.Type: GrantFiled: October 26, 2015Date of Patent: August 22, 2017Assignee: TIER 1 ENERGY SOLUTIONS INC.Inventors: Kevin O'Dwyer, Jeffrey Golinowski, Nathan Kathol
