    Abstract: The invention provides an apparatus (300, 400) for actuating a downhole tool (700) by utilizing a pressure differential created by fluid flowing through a restriction in a conduit (315). The conduit is in communication with a pressure sensing line (400) that is selectively exposable to areas of near the restriction in the conduit (316, 317) having different pressures. By exposing the pressure sensing line to a portion of the conduit having a predetermined pressure therein, the pressure sensing line causes actuation of a hydraulic tool therebelow. The apparatus is of particular use for a single trip sidetrack system in combination with an MWD-tool, a whipstock, and an anchor packer without a bypass valve.

    Abstract: Methods and apparatus for conducting fracturing operations using a wellbore fracturing assembly are described. The assembly may be mechanically set and released from a wellbore using a coiled tubing string. The assembly may include a pair of spaced apart packers for straddling the area of interest, an injection port disposed between the packers for injecting fracturing fluid into the area of interest, and an anchor for securing the assembly in the wellbore. At least one of the packers includes a pressure balanced mandrel. After conducting the fracturing operation, the assembly may be relocated to another area of interest to conduct another fracturing operation.

    Abstract: A collar (500) for injecting fluid, such as a formation treating fluid, into a wellbore, and a method for using same. The collar is disposed between the upper and lower packing elements (40, 41) of a pack-off system during the treatment of an area of interest within a wellbore. The collar first comprises an inner mandrel (550) running essentially the length of the collar. The inner bore of the collar is in fluid communication with the annular region between the collar and the surrounding perforated casing by a set of actuation ports (552). A second set of ports (554), known as frac ports, is disposed within the mandrel. In accordance with one aspect of the invention, the collar further comprises a tubular case which substantially seals the frac ports in a first position, and slidably moves along the outer surface of the mandrel in order to expose the frac ports in a second position. In operation, the upper and lower packing elements are set at a first fluid pressure level. Upon application of a second greater fluid pressure level, the upper and lower packing elements are further separated in accordance with a designed stroke length, thereby exposing the frac ports.
