A downhole wireless actuation based pipe lifting system with wireless communications and data acquisition capabilities for lifting casing from a well formation. The system may be deployed along a casing string with centralizers in the closed position to prevent any resistance that would be created by the centralizers. Upon reaching the proper location in the well, one or more pipe lifting systems may be actuated to lift the pipe from the well formation thereby providing a path for cement to flow around the casing. The system may collect, and store data before, during, and after the cementing process is performed, and may transmit the data wirelessly or by cable. |

1. A downhole wireless actuation and data acquisition based pipe lifting system with wireless communications, comprising:
a. a substantially tubular housing deployed along a pipe string, the substantially tubular housing comprising:
i. a hermetically sealed interior adapted to surround a pipe; andii. an outer assembly, the outer assembly further comprising:
1. a plurality of arms adapted to selectively increase or decrease the resistance between the wellbore and the pipe; and b. a power source; c. an actuation module disposed within the interior of the housing, the actuation system adapted to selectively engage and move one Or more of the plurality of arms; d. an electronics module disposed within the interior of the housing, operatively connected to the power source, and operatively in communication with the actuation system; e. a sensor module housed at least partially within the interior of the housing, operatively in communication with the electronics module; and f. a communications module disposed within the interior of the housing, operatively in communication with the electronics module. |
