12. A method for initiating or logging natural flow in a production tubing, the method comprising:
conveying a bottom hole assembly (BHA) on a wireline to a predetermined depth into the production tubing, the BHA comprising:
an electrical submersible pump (ESP) having an outer diameter smaller than an inner diameter of the production tubing; and
a multi-resettable packer assembly, the multi-resettable packer assembly comprising:
a first multi-resettable packer having a first packer ring and a second packer ring;
a port sub coupled below the first packer ring on the first multi-resettable packer, wherein the port sub is configured to hydraulically connect the production tubing to the ESP;
an inner mandrel disposed inside the first multi-resettable packer and axially movable within the first multi-resettable packer and the port sub, the inner mandrel having a first end and a second end, the second end coupled to the second packer ring on the first multi-resettable packer, the inner mandrel having at least one intake port proximate the first end configured to allow fluid from outside the inner mandrel to an inner bore of the inner mandrel; and
a stroker tool configured to compress and decompress the first multi-resettable packer to seal and unseal, respectively, against an inner surface of the production tubing, the stroker tool comprising a plurality of slips configured to grip the inner surface and a piston configured to extend from and retract into the stroker tool, wherein an end of the piston is coupled to the first end of the inner mandrel; and
receiving operating data by a control system via a sensor disposed on the BHA configured to measure operating data, the operating data comprising a pressure measurement;
compressing the first multi-resettable packer by retracting the piston into the stroker tool in response to a first signal sent by the control system based, at least in part, on the received operating data through a power and communications bus configured to power and transmit the first signal to the BHA, the compressing the first multi-resettable packer comprising forming a seal between the BHA and the inner surface of the production tubing; and
decompressing the first multi-resettable packer by extending the piston out of the stroker tool and into the port sub in response to a second signal sent by the control system based, at least in part, on the received operating data, the decompressing the first multi-resettable packer comprising releasing the seal between the BHA and the inner surface of the production tubing.
