<p>The present invention relates to an improved method for multilateral completion and cementing (i.e., sealing) the juncture between primary and lateral wellbores. It is desirable to have the ability to re-enter each lateral wellbore as well as maintain the option to perform any function that could be done in a single wellbore. The method of this invention utilizes a 'hook' liner hanger system. The hook liner hanger system includes a novel camming surface and guide slot (114) which cooperates with a complimentary control lug to selectively direct a tool in a primary or lateral wellbore.</p> |
