  • Drill string safety valve device
    Patent number: 11415237
    Abstract: A drill string safety valve device (1) has a body (2) with a through-going flow bore (25) and connectors (3, 4) at respective ends (19, 18) for connection to tubulars, such as pipe joints. A valve member (7; 29) is movably arranged in said flow bore (25) and configured for being set in one of two states: a first state of the valve member allows fluid to flow in both directions though the flow bore, and a second state of the valve member allows fluid flow through the flow bore in only one direction. The valve member may be a rotatable ball valve (7) with a through-going flow bore (21).

  • Centralizer device and method for deployment of a bore hole component in a borehole
    Patent number: 10626682
    Abstract: A centralizer device for center positioning of a bore hole component (90, 91) in a bore hole and a method for deploying such a centralizer are described. The centralizer device (100) is prepared to have two possible different states, one state being a locked state for improved deployment and another state being a released state for centring. The transition from the locked state to the released state is performed by introducing a pill of bore fluid having a pH-value outside range of pH-values of bore fluid in a well. The pill of bore fluid dissolves pH-soluble material in the centralizer device.
