Electrically operated well completion apparatus and method
An electrically operated well completion system is described for a hydrocarbon producing well having a tubing production string in a well casing comprising, an electrically actuated lower and upper well packer in the production string and electrically controlled from the well surface for sealing between the production string and the casing, a transducer connected to the lower or upper well packer and electrically connected to the well surface for determining when the packer is set, an electrically actuated safety joint in the production tubing above the upper packer for reducing the strength of the production tubing at the safety joint when actuated, an electrically actuated well annulus safety valve connected to the production string for controlling fluid flow between the production string and the casing, a transducer connected to the annulus safety valve and electrically connected to the well surface for determining the position of the annulus safety valve, a solenoid actuated tubing safety valve connected to the production string below the safety joint for controlling fluid flow through the production string, a transducer connected to the solenoid valve and electrically connected to the well surface for determining the position of the solenoid actuated safety valve, an electrically controlled circulating sleeve in the production string between the upper and lower packers for controlling communication between the outside and the inside of the production string, transducer means connected to the sleeve and electrically connected to the well surface for measuring the position of the sleeve, an electrically operated blanking block valve in the production string below the circulating sleeve for blocking off downward fluid flow through the bore of the production string, and a transducer connected to the block valve and electrically connected to the well surface for determining the position of the block valve.
