Abstract
Official abstract text for this publication.
A disconnector drill string has an uphole section and a downhole section coupled together by a disconnection sub, an operative length and an internal fluid conduit that extends along its operative length. The disconnection sub is operable to receive wirelessly a pre-designated command signal, to selectively couple the uphole section and the downhole section together, and to selectively uncouple the uphole section and the downhole section from one another. A method for using the disconnector drill string in a well bore includes the steps of introducing the disconnector drill string into the well bore, transmitting wirelessly the pre-designated command signal to the disconnection sub such that the disconnection sub selectively operates to uncouple the uphole section of the disconnector drill string from the downhole section of the disconnector drill string, and removing the uphole section of the disconnector drill string from the well bore.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for using a disconnector drill string in a well bore comprising the steps of: introducing the disconnector drill string into the well bore, where the disconnector drill string has a disconnection sub, an internal fluid conduit, an operative length, first uphole section and a downhole section that are coupled together by the disconnection sub, the first uphole section positioned uphole of the downhole section along the operative length of the disconn…
