Methods and electrically-actuated apparatus for wellbore operations
First Claim
1. A method of deploying and positioning a bottom hole assembly (BHA) in a wellbore comprising:
- deploying the BHA into the wellbore, the BHA being electrically-enabled from surface and comprising at least one packer having an electrically-actuable packer element;
electrically actuating the packer element to expand to a running diameter being less than a diameter of the wellbore;
pumping fluid through an annulus between the wellbore and the BHA, the packer element acting as a hydraulic piston for pumping the packer and the BHA downhole in the wellbore; and
electrically actuating the packer element to expand to a sealing diameter for sealing the annulus.

Abstract
Embodiments of a bottomhole assembly (BHA) for completion of a wellbore are deployed on electrically-enabled coiled tubing (CT) and permit components of the BHA to be independently electrically actuated from surface for completion of multiple zones in a single trip using a single BHA having at least two electrically-actuated variable diameter packers. One or both of the packers may be actuated to expand or retract for opening and closing off a variety of flowpaths between the BHA and the wellbore, in new wellbores, old wellbores, cased wellbores, wellbores with sleeves and in openhole wellbores. Additional components in the BHA, which may also be electrically—actuated or powered, permit perforating, locating of the BHA in the wellbore such as using casing collar locators and microseismic monitoring in real time or in memory mode.
