Abstract
An apparatus for deploying an instrument usable with a well comprises at least one reversibly expandable structure, at least one actuator operable to change a perimeter dimension of the at least one reversibly expandable structure, at least one instrument disposed interior of the at least one reversibly expandable structure, and having an axial dimension, and tractoring fluid disposed between the at least one reversibly expandable structure and the at least one instrument. The apparatus is operable to perform at least one of exerting thrust to convey the at least one instrument with respect to at least one adjacent surface, creating compensating pressure between the at least one instrument and the at least one adjacent surface, and sealing between the at least one instrument and the at least one adjacent surface.
