Abstract
System and method for a bottom hole assembly (BHA) in production tubing including an electrical submersible pump (ESP), multi-resettable packer assembly, sensor, power and communications bus, and control system. The multi-resettable packer assembly includes a multi-resettable packer, a port sub hydraulically connecting production tubing to the ESP, an inner mandrel inside the multi-resettable packer axially movable within the multi-resettable packer and port sub, and a stroker tool configured to compress and decompress the multi-resettable packer to seal and unseal an inner surface of production tubing. The stroker tool includes slips to grip the inner surface and a piston that extends from and retracts into the stroker tool. The sensor is configured to measure operating data including a pressure measurement. The power and communications bus powers and transmits signals to the BHA. The control system monitors operating data and controls the stroker tool via the power and communications bus.
