Abstract: Apparatus and a method for delivering a rod in a cylinder including propagating a rod in a cylinder along the interior of the cylinder, and introducing a motion in an orientation orthogonal to a length of the rod, wherein the motion comprises multiple motion sources along the length of the rod, and wherein the multiple motion sources comprise a control system that controls at least one of the motion sources. An apparatus and method for delivering a rod in a cylinder including a cylinder comprising a deviated portion, a rod comprising a length within the cylinder, multiple motion sources positioned along the length of the rod, and a control system in communication with at least one of the motion sources, wherein the control system controls the location of frictional contact between the rod and cylinder over time.

Abstract: A technique for determining conditions downhole in a well, particularly load conditions acting on a well tool, e.g. a bottom hole assembly. The loads acting on a bottom hole assembly or other well tool during a well related operation are measured. Load data is collected and may be transmitted uphole in real time for evaluation at a surface control unit. Based on the load data and other possible data related to the downhole operation, corrective actions can be taken to improve the operation.

Abstract: An apparatus for engaging with an outside diameter of a tubular comprises a device body having an internal surface that defines an internal diameter in a first position and allowing the tubular to pass therethrough and an actuator operable to move the internal surface of the device body from the first position to a second position, the second position defining an internal diameter less than the first position internal diameter. The internal surface of the device body is sized with a predetermined grip length for engaging with the outside diameter of the tubular. The grip length is determined by a function of the outside diameter of the tubular and the coefficient of friction between of the outside diameter of the tubular and the interior surface of the device body and the device body is operable to engage with a tubular having a predetermined range of outside diameters.

Abstract: An apparatus for deploying an instrument usable with a well comprises at least one reversibly expandable structure, at least one actuator operable to change a perimeter dimension of the at least one reversibly expandable structure, at least one instrument disposed interior of the at least one reversibly expandable structure, and having an axial dimension, and tractoring fluid disposed between the at least one reversibly expandable structure and the at least one instrument. The apparatus is operable to perform at least one of exerting thrust to convey the at least one instrument with respect to at least one adjacent surface, creating compensating pressure between the at least one instrument and the at least one adjacent surface, and sealing between the at least one instrument and the at least one adjacent surface.

Abstract: A system for reducing the effects of heave movements of a wellhead in an offshore drilling device is provided that includes a frame; a coiled tubing stack supported by the frame; and a heave compensation system for controlling an amount of load transferred from the coiled tubing stack to the wellhead to reduce relative movements between the coiled tubing stack and the wellhead.

Abstract: The present invention is a compensated coiled tubing unit for use in off-shore applications. The unit includes a mechanism for providing both vertical and horizontal heave compensation. The heave compensation mechanism is incorporated into the jacking frame of the unit. The coiled tubing unit also includes a flexible riser system that connects the wellhead to the coiled tubing stack.
