Multilateral Work-Overs: A New Possibility with Coiled Tubing

John Edward Ravensbergen

The number of fields being developed or redeveloped using multilateral wells to enhance effective drainage is increasing. Some of these wells have complex Level 3 or higher junctions, but the majority are still Level 1 junctions. A new bottomhole assembly (BHA) and lateral-entry guidance system (LEGS) that intelligently navigates through a junction enables multilateral wells to be worked over with coiled tubing (CT).
