Case Study of Intelligent Completion with New Generation Electro-Hydraulic Downhole Control System

摘要

Extended reach wells with thousands of feet of open hole reservoir contact and multilateral wells with eight to 10 laterals are becoming common practice as the industry develops tight and difficult reservoirs. Over the years, drilling and well construction technologies have made significant advances in the field of geosteering, multilateral junctions, etc., to make these complicated wells not just a reality but also commonplace. The industry has recently introduced several new well completion technologies for the downhole monitoring and inflow control of these extended reach and multilateral wells. Over the last 10 years, Saudi Aramco has drilled and completed hundreds of multilateral wells with intelligent completions for real-time downhole monitoring and for remote valve operation to control inflow from each lateral. These technologies have improved well performance and reduced well intervention.
