First Multilateral Well Worldwide with an Intelligent Completion System and Open Hole Acid Stimulation

摘要

The Middle East has long been a pioneer in innovation in drilling and completion technologies for multilateral wells. It was here that the first1 multilateral tool (MLT) on coiled tubing (CT) was used to access and stimulate each open hole lateral in a trilateral well. Over the years, several2"4 applications of this and similar technologies have been made. In each instance, a conventional upper completion system was installed. In a multilateral well with a conventional upper completion and an open hole lower completion, there is no independent flow control from each lateral. Because of this, production is not optimized to account for differences in the production rate or reservoir quality of each lateral. For a well with an upper intelligent completion system (ICS), independent control of flow from each lateral is possible through the use of surface controlled flow control valves (FCVs). This feature addresses the shortcomings of the conventional upper completion previously mentioned.
