    Abstract: The disclosure provides devices, systems and methods for obtaining unaliased wavefield data despite using spatial sampling distances that are higher than conventional techniques and temporal sampling rates that are lower than conventional techniques. The devices can include an array of sensors for sampling a desired wavefield and at least one of its derivatives. The systems can include a multi-level array of such sensor configurations. The methods can include lowering such an array into a borehole and sampling data at distances that are greater than suggested by conventional theory, or lowering a multi-level array into a borehole and simultaneously gathering data at different depth levels.

    Abstract: A method comprising moving a shifting tool in a first direction through a moveable member positioned in a casing of a wellbore, including moving the shifting tool through a shifting tool interface member (STIM) adjacent the moveable member, until the shifting tool is positioned past the moveable member and the STIM. The shifting tool is then moved in a second direction substantially opposite the first direction until the shifting tool and the STIM engage. The shifting tool is then further moved in the second direction, thereby moving the STIM and the moveable member in the second direction, until the STIM substantially simultaneously (1) engages the casing and (2) disengages the shifting tool.
