Patent number: 10613691Abstract: A downhole apparatus including a tubular body, first and second ports in a wall of the body, and a fluid pressure-responsive valve arrangement having a locked first configuration associated with a first pressure in which the first port is open and the second port is closed, an unlocked second configuration associated with a second pressure higher than the first pressure in which the first port is open and the second port is closed, and a third configuration associated with a third pressure lower than the second pressure in which the second port is open and the first port is closed.Type: GrantFiled: November 16, 2017Date of Patent: April 7, 2020Assignee: HALLIBURTON MANUFACTURING AND SERVICES LIMITEDInventors: Stephen Edmund Bruce, Stephen Kent, Dominic Patrick Joseph McCann, David Allan Noblett, David Grant, Ewan Colin Smith

Patent number: 10428631Abstract: A method is for use with subterranean formations, such as oil and/or gas reservoirs. In some examples (e.g., production examples), the method improves the production from that formation. Some of the examples of the method describe selecting both an exertive force (e.g., a pressure) to apply at a wellbore, but together with a drawdown pressure at the wellbore to modify operations (e.g., improve production) at that subterranean formation. The selection of one or both of the exertive force and drawdown pressure may be based on the downhole environment at that wellbore, which can include the porosity and/or permeability of a near-wellbore formation radially surrounding a wellbore. The exertive force and drawdown pressure may be specifically selected to modify the porosity and/or permeability of the near-wellbore formation.Type: GrantFiled: June 14, 2013Date of Patent: October 1, 2019Assignee: HALLIBURTON MANUFACTURING AND SERVICES LIMITEDInventors: David Allan Noblett, Stephen Edmund Bruce, Dominic Patrick Joseph McCann, Stephen Kent

Patent number: 9353606Abstract: A method of injecting fluid into a formation, comprises exerting a mechanical force on a wall of a bore extending through a formation to modify the permeability of the formation; and injecting fluid into the modified formation. The mechanical force may be exerted through inflation of at least one pressure deformable member mounted on a base member. The base member may be a base pipe. The pressure deformable member may be a hollow or tubular member mounted externally of the base pipe. A plurality of pressure deformable members are provided.Type: GrantFiled: November 16, 2011Date of Patent: May 31, 2016Assignee: Darcy Technologies LimitedInventors: Stephen Edmund Bruce, Stephen Kent, Dominic Patrick Joseph McCann, David Allan Noblett, David Grant
