Title: APPARATUS AND METHODS FOR ORIENTATION OF A TUBULAR STRING IN A NON-VERTICAL WELLBORE
Abstract:
An apparatus and method for orienting tubular strings in wellbores. In one aspect, the invention utilizes the inherent eccentricity of a non-vertical wellbore (160) to provide a means of orienting a portion of casing (100) that contains a pre-milled window (110). The orienting member (140) can be an orientating sleeve (140) disposed around the tubular (100) and substantially covering the window (110).
