Abstract: Systems and methods for conveying power and data between surface equipment, an ESP and one or more remote tools while requiring a reduced number of penetrations through a tubing hanger. In one embodiment, a primary cable carries power and data between surface equipment and the ESP. A separate secondary cable is coupled between the ESP and the remote tools. The ESP receives power from the surface equipment via the primary cable, and the remote tools receive power from the ESP via the secondary cable. A step-down transformer in the ESP transforms power to reduced-voltage AC power, or a rectifier produces rectified DC power which is provided to the remote tools via the secondary cable. A transceiver in the ESP communicates data between the surface equipment and the remote tools. Data and power for the ESP and remote tools are conveyed through a single common penetration in a tubing hanger.

Abstract: In one aspect, an apparatus for use in a wellbore is provided that may include: a tool configured to be conveyed into the wellbore by a conveying member; and an electro-active polymer device (“EAP device”) configured to connect the tool to the conveying member when the EAP device is in a first mode or position and disconnect the tool from the conveying member when the EAP device is in a second mode or position. In another aspect, a method for releasing a tool in a wellbore is provided which includes: releasably connecting an EAP device to a conveying member and the tool; conveying the tool in the wellbore with the conveying member; and electrically activating the EAP device to release the tool from the conveying member in the wellbore.

Abstract: A subterranean formation stimulation system, comprising a gas generator, a high pressure seal, and a fluid injection system. The high pressure seal may be a packer and or plug having an outer sealing surface on its outer periphery. The outer sealing surface is configured for metal to metal contact with the inner circumference of wellbore casing. The gas generator can be compressed gas or a propellant. A shaped charge can be included to activate the generator. The system is disposable in a wellbore on wireline, slick line, or tubing.
