Abstract: An embodiment of an apparatus includes an actuatable downhole tool with a brush actuator that includes brush elements extending outwardly from a slide member that surrounds a mandrel having a proximal end connectable to a tubular string. The brush elements are sized to engage a casing into which the apparatus is disposed. A spring element is disposed intermediate the slide member and the mandrel to bias the mandrel to a proximal position. A transition mode of the brush elements is achievable by reversing the direction of movement of the apparatus within the casing from the trailing up mode towards the trailing down mode and provides a sufficient amount of resistance to overcome the spring element to move the slide member to a distal position and displace a displaceable member of the actuatable downhole tool to actuate the tool.

Abstract: A method and apparatus for an open throat power tong is provided to cover the rotary region of the power tong, including the pipe slot, wherein numerous moving parts may cause injury due to accidentally misplaced fingers or hands. Top and bottom movable guard portions, movable between open and closed positions, operate in conjunction with top and bottom fixed guard portions to cover the rotary region. When the movable guard portions are in the open position, hydraulic oil flow to a hydraulic power tong motor is completely blocked rather than diverted so as to avoid slow creep of the motor. Sensors that detect the open and closed position of the guards are placed in series so that all sensors must be shifted to allow tong motor operation. The movable guard portions may be pivotally mounted to a rear segment of the fixed guard portion.

Abstract: Equipment and techniques test the integrity of one or more seals within an oilfield tubular threaded connection 12. A test fixture 74 may be utilized including three axially spaced sensors 92, 86 and 88 which are each responsive to radial deformation of an outer surface of an internally pressurized threaded connection. Excessive radial deformation indicates a failure of at least one of the threaded connection seals. A relatively simple yet highly reliable technique is provided for quickly and easily determining the sealing integrity of a threaded connection made up at a well site. If any one of the multiple seals fails during the test, the operator may either break out and re-test the connection, or may make up and test a new threaded connection. The present invention may be used for substantially increasing the integrity of oilfield tubular connections and thereby reducing the overall cost of hydrocarbon exploration and recovery operations.
