Patent number: 9291034Abstract: A tool for selectively treating a wellbore with fluid that includes a tubing string having a sidewall defining an inner bore, the sidewall comprising a flow area having at least one fluid flow port that permits fluid flow through the sidewall. Fluid is prevented from flowing through the flow area when a closure is in a closed position. When in the open position, fluid flows through the flow area. An axial seal is connected to the closure to selectively close the inner bore against fluid pressure to apply the predetermined opening force to move the closure to the open position. A releasable connector connects the axial seal to the closure and a retrieval tool attachment releases the axial seal from the closure upon application of a predetermined release force by a retrieval tool.Type: GrantFiled: April 26, 2010Date of Patent: March 22, 2016Assignee: Logan Completion Systems Inc.Inventors: Don Turner, Grant George

Publication number: 20140367933Abstract: A snowboard without foot bindings enables a rider to perform skateboard tricks while sliding on snow. A pair of runner boards is connected in a spaced longitudinal relationship by a strut. A pole is attached to the strut by a universal joint enabling a rider to perform maneuvers while holding onto a handle at the end of the pole. The universal joint enables the runner boards to rotate 360° about a longitudinal axis extending along the board and rotate 360° about a vertical axis and other angles therebetween providing the same freedom of movement to the runner boards that a skateboard provides for its rider. The pole is pivotally mounted to the connector enabling the pole to pivot through an arc of at least 180°.Type: ApplicationFiled: June 14, 2013Publication date: December 18, 2014Inventors: Grant George Robert Winchester, Robert G.

Patent number: 8387710Abstract: A downhole valve for insertion in a production tubing string permits recirculation of fluid pumped into the casing annulus. The valve includes a cylindrical housing defining an opening, an internal mandrel disposed within the housing, defining a central bore and defining an opening, a valve between the housing and the mandrel, wherein said valve opens to allow fluid communication from the mandrel central bore to the annulus space in response to a pressure differential between the mandrel central bore and the annular space, and biasing means for biasing the valve in a closed position. The valve may be set within a completion string by wireline techniques.Type: GrantFiled: March 5, 2009Date of Patent: March 5, 2013Assignee: Stellarton Technologies Inc.Inventors: Grant George, Geoff Steele, Jordan James
