Abstract: Techniques for correlating depth on a tubular in a wellbore include a casing collar locator tool that includes a tubular mandrel defining a bore therethrough; a top sub-assembly and a bottom sub-assembly carried on the tubular mandrel; a profile carried on the tubular mandrel axially between the top sub-assembly and bottom sub-assembly and adjustable between an engaged state defined by the profile extending radially away from the mandrel and a disengaged state defined by the profile refracted towards the mandrel; and a wedge sleeve carried on the tubular mandrel between the top sub-assembly and the bottom sub-assembly and arranged, at least in part, axially adjacent the profile, the wedge sleeve actuatable to urge the profile into at least one of the engaged state or the disengaged state.

Abstract: An apparatus comprising a tubular body defining a flowbore, a first valve that, when activated, restricts fluid communication via the flowbore in a first direction and allows fluid communication in a second direction, and, when deactivated, allows fluid communication in the first and second directions, a first sleeve slidable from a first to a second position that, when in the first position, the first valve is activated, and, when in the second position, the first valve is deactivated, a second valve, that, when activated, restricts fluid communication in the first direction and allows fluid communication in the second direction, and, when deactivated, allows fluid communication in the first and second directions, and a second sleeve slidable from a first to a second position, that, when in the first position, the second valve is deactivated, and, when in the second position, the second valve is activated.

Abstract: Embodiments of the hybrid tool string include coiled tubing and jointed tubing, as well as a means typically located at the connection of the coiled and jointed tubing for sealing the fluid flowpath through the bore of the hybrid tool string. Embodiments of the hybrid tool string may use a pressure-activated valve tool attached in series between the coiled tubing and the jointed tubing, which allows for sealing of the bore by application of pressure. Embodiments of the pressure-activated valve tool may use a flapper in conjunction with a sleeve to seal the bore. The novel hybrid tool string may be used to service a well.

Abstract: A spoolable connector which connects two opposing sections of coil tubing so as to transmit load between one section of coil tubing and another section of coil tubing. The spoolable connector has opposing non-circular grooves into which portions of the sections of coil tubing are deformed so as to create the torque transmitting connection between the spoolable connector and sections of coil tubing. The spoolable connector also includes a plurality of parallel radial slots on each opposing end to enhance bending of the connector at the ends as well as a plurality of longitudinal slots at each end to accommodate the weld seam line in the coil tubing. Seals may be installed as a sleeve which in use fits over the mid-section of the connector.

Abstract: A connector which joins two opposing sections of coil tubing or coil tubing to coil tubing tools so as to enable torque applied from one section to be transmitted to the other section is provided. The connector employs varying width and depth grooves into which portions of the sections of coil tubing are deformed so as to create the torque transmitting connection between the connector and sections of coil tubing. Each of the grooves have a narrow width portion and a wide width portion and corresponding shallow depth and deep depth portion. The narrow width portion of one of the grooves is approximately 180° out of phase from the narrow width portion of the other varying width groove.
