Abstract: An apparatus with a straddle packer for use within a wellbore. The straddle packer can include a tubular body comprising a first bore and a second bore and a first sealing element configured to seal against an inner surface of a casing installed within the wellbore. A second sealing element configured to seal against the inner surface of the casing, and the second bore can be located between the first sealing element and the second sealing element. An obstruction disposed in association with the tubular body, wherein the obstruction is movable between a first position in which the obstruction opens the second bore and a second position in which the obstruction closes the second bore.

Abstract: Apparatus and methods for performing downhole torqueing. The apparatus may be a downhole tool for rotating a first downhole equipment disposed within a wellbore. The downhole tool may include first and second rotative members operable to rotate relative to each other along an axis of the downhole tool. The downhole tool may further include a first gripping member connected with the first rotative member and operable to engage the first downhole equipment, and a second gripping member connected with the second rotative member and operable to engage a second downhole equipment. An actuator may be operable to impart a force to cause the relative rotation between the first and second rotative members thereby causing rotation of the first downhole equipment when the first gripping member is connected with the first downhole equipment and the second gripping member is connected with the second downhole equipment.
