<p>A system and method of locating and entering a lateral wellbore (25,35) that extends from a primary wellbore (5) are provided. The system may include a coiled tubing (10) jointed tubular (10) continuous rod (10) and/or wireline conveyance menber (10), a connection assembly (20), an orientation assembly (32), a measurement assembly (40), a deflection assembly (50), a sub assembly (60), and a guide assembly (74). The method may include locating a tool string adjacent to a lateral wellbore that extends from a primary wellbore, measuring an inclination and azimuth of the tool string, comparing the measured data to existing survey data of at least one of the primary and lateral wellbores, orinting the tool string in the direction of the lateral wellbore, entering the lateral wellbore, and verifying that the tool string has entered the lateral wellbore.</p> |
