Abstract
A method and apparatus of electrically and sequentially completing an oil and/or gas well through a tubing production string in a well casing.

Claims4
An electrically actuated well packer for use in a well for sealing between a production string and well casing comprising,
- a body having a bore therethrough,
- initially retracted packer seal means surrounding said body,
- initially retracted slip means surrounding said body,
- fluid actuated piston means connected to the body for expanding and setting the slip means and the packer seal means,
- an initially closed fluid chamber in the body containing a pressurized fluid source,
- a frangible member initially blocking communication between the piston means and the fluid chamber, and
- an electrical motor in the body connected to the frangible member for breaking the member and allowing fluid source in the chamber to actuate the piston means.
