Abstract
This paper presents some of the experience of drilling and completing level 4 and 5 multilateral wells in deep waters of the Campos Basin, in the last three years. It presents the reason for this initiative, a general description of the several types of junction building processes (both milled and pre-milled window systems) and some aspects of the wells that were drilled and completed: the Bonito well (water depth:200m); Voador well (water depth: 565 m) and the two Barracuda wells (water depth: 802m/ 850m). This paper also shows the lessons learnt during these complex projects and concludes that the multilateral well technology became a viable alternative for subsea development.
