    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: An actuatable wellbore isolation assembly comprising a housing generally defining an axial flowbore and comprising a mandrel portion, a first end portion, and a second end portion, a radially expandable isolating member positioned circumferentially about a portion of the housing, a sliding sleeve circumferentially positioned about a portion of the mandrel of the cylindrical housing, the sliding sleeve being movable from, a first position in which the sliding sleeve retains the expandable isolating member in a narrower non-expanded conformation to a second position in which the sliding sleeve does not retain the expandable isolating member in the narrower non-expanded conformation, and an actuator assemblage configured to selectively allow movement of the sliding sleeve from the first position to the second position.
