20140299323 | DOWNHOLE TOOL - A downhole tool mechanism for applying a driving force, such as a cutter tool for cutting a line captured within the tool, comprises a resiliently compressible member for storing a compressive force; a retaining device for maintaining storage of the compressive force until released; a trigger mechanism for releasing the compressive force when the trigger mechanism is activated. In one form the resiliently compressible member comprises a plurality of concentrically arranged spring washers each having a radial slot therein for receiving a line along the length of the resiliently compressible member. In the cutter form, there is a cutter arranged to cut the line when the trigger mechanism is activated, and the trigger mechanism is activated when the tool receives a shock force to one or both ends. | 10-09-2014 |
20140182699 | FLUSHING TOOL AND METHOD OF FLUSHING PERFORATED TUBING - A flushing tool for a perforated tubing in a production tubing string is described. The flushing tool includes a chamber that is sealed at a pressure at or below atmospheric pressure when the flushing tool is in its sealed configuration, the chamber arranged to receive wellbore fluids when the flushing tool is in its activated configuration. A port allows ingress of wellbore fluids into the chamber when the flushing tool is in its activated configuration. A sealing means has a first position when the flushing tool is in its sealed configuration and a second position when the flushing tool is in its activated configuration. An actuator releases the flushing tool from its sealed configuration to its activated configuration by releasing the sealing means to move from the first position to the second position. | 07-03-2014 |
