Abstract:
A system for deploying sensors throughout a vertical section and a horizontal section of an unconventional well comprises a mandrel comprising a set of extendable arms; a conductivity sensor mounted on a first predetermined subset of the set of movable arms; a strain sensor mounted on a second predetermined subset of the set of movable arms; a first downhole tool configured to be placed in the horizontal section of the unconventional well; a second downhole tool placed in a vertical section of the well, the first downhole tool and the second downhole tool adapted to operate simultaneously; a navigation package; a real time communications short hop data communicator; a data communicator; a downhole power source; and a surface system configured to collect and process data obtained in the well. The system can be used to provide data to evaluate conditions in the well and its reservoirs as well as frac height and frac width.
