World's first level 6 intelligent completion reveals economic potential of multilateral

摘要

The world's first technology advancement for multilaterals (TAML) level 6 intelligent completion could help steer the industry to develop similar installations for new wells and reentry applications. The primary incentive to apply the multilateral well technology by Schlumberger and the China National Offshore Operating Co. on this project in the South Java Sea off Indonesia was minimizing further capital investment of installing an additional platform structure by maximizing usage of existing slots. Costing less than two horizontal wells, not including fishing operations, this intelligent completion allowed for optimized setting of the downhole choke and delayed water influx. Over the years, the understanding of field structure has evolved and revealed some significant amount of oil left between existing wells in smaller isolated targets. Multilateral technology makes it possible to penetrate more of the reservoir while using only one slot and to achieve greater flow rates from individual parent well-bores, increasing total field production by drilling all infill wells in the development program and combining the targets.
