Abstract
Wireless downhole sensor technology is being deployed in oil and gas wells. System components are inductively coupled, which enables remote placement of apparatus on the outside of wellbore conduit without the need for any wired connection. These systems make use of a pair of conductive elements that need to be aligned in the well. Embodiments of the present invention provide techniques to correctly space out the wellbore completion string so that the down-hole conductive elements will be properly aligned and within proximity to establish wireless connectivity, as the wellbore completion string is set and the tubing hanger is landed inside the wellhead housing of the well.
