Electronically-Actuated, Multi-Set Straddle Borehole Treatment Apparatus

A straddle fluid treatment apparatus deployed in a borehole with tubing, the apparatus comprising:

• first and second packers disposed on the apparatus and having—
• at least one fill port in fluid communication with the tubing, and
• at least one packer valve biased to open fluid communication between the at least one fill port and the first and second packers;
• a flow unit disposed on the apparatus between the first and second packers and having—
• a flow port in fluid communication with the tubing, and
• a flow valve biased to close fluid communication between the flow port and the borehole;
• and
• one or more control units operatively coupled to the at least one packer valve and the flow valve and detecting at least one activation, the one or more control units electronically activating the at least one packer valve in response to the at least one detected activation to close fluid communication between the first and second packers and the at least one fill port, the one or more control units electronically activating the flow valve in response to the at least one detected activation to open fluid communication between the flow port and the borehole.

A method of treating sections of a borehole, the method comprising:

• deploying an apparatus on tubing to one of the sections of the borehole;
• setting first and second packers of the apparatus against the borehole by pumping fluid pressure down the tubing and through at least one packer valve opened on the apparatus;
• trapping the fluid pressure in the first and second packers by electronically closing the at least one packer valve;
• electronically opening at least one flow valve disposed on the apparatus between the first and second packers;
• and
• pumping treatment from the tubing to the section of the borehole through the open flow valve.
