Abstract: Systems and methods for gripping a polished rod that extends into a hydrocarbon production well include a clamping assembly that is moveable between an unengaged position where the clamping assembly is spaced apart from the polished rod, and an engaged position where the clamping assembly engages the polished rod. The clamping assembly includes a recess located in a moveable clamping member, the recess having a supporting surface. The clamping assembly also includes an adapter sized to fit within the recess and to be supported on the supporting surface, the adapter having a gripping surface facing out of the recess. The adapter is positioned to grip the polished rod with the gripping surface when the clamping assembly is in the engaged position.

Abstract: A pumping system for use in a subterranean wellbore below a surface includes a motor assembly, a pump driven by the motor assembly, and one or more sensors configured to measure an operating parameter within the pumping system and output a signal representative of the measured parameter. The pumping system further includes a wireless telemetry system that is configured to transmit data representative of the measured parameter from the pumping system to the surface. The one or more sensors may include acoustically active sensors that operate according to surface acoustic wave principles.

Abstract: A system for monitoring the orientation and position of components in an oil well. The system includes a first well component, a second well component, and a transducer attached to the first well component, for generating a pulse. The system also includes a transceiver attached to the second well component for measuring the parameters of the pulse generated by the transducer, and a processor in communication with the transceiver that receives information about the parameters of the pulse as measured by the transceiver, and that calculates the position of the transceiver relative to the transducer.

Abstract: A system for load transfer from a wellhead to the sea bed adjacent a subsea well, including a suction pile for securing to the sea bed, and a wellhead housing assembly having a longitudinal axis and attached to the suction pile, the wellhead housing for subjection to an axial load acting in a direction parallel to the longitudinal axis, and a bending load acting in a direction not parallel to the longitudinal axis. The system further includes a suction pile connector that transmits the axial load and the bending load from the wellhead housing through the suction pile toward the sea bed, and that is attached to the suction pile, the suction pile connector engaged with the wellhead housing to substantially maintain the relative positions of the wellhead housing and the suction pile.

Abstract: An apparatus including a first actuator including a first housing defining a first internal region, a first head disposed in the first internal region, the first head defining first and second portions of the first internal region, and a first elongated member connected to the first head and extending out of the first housing. The apparatus further includes a first arm connected to the first elongated member to transfer to the first elongated member at least a first portion of a first force applied in a first direction by at least the weight of at least a tubular component, and a first pressurized fluid source in fluid communication with the first portion of the first internal region to apply a second force against the first head in a second direction that is opposite the first direction. According to one aspect, the tubular component is part of a quill.
