Multilateral completion technology

摘要

The conference paper focuses on the recent advances and developments in completion systems to address multilateral completions with current capabilities and trends. The systems, with their advantages and disadvantages included, are as follow: Generic application variants; multi-branch system with isolation; dual lateral systems; combination system with full selective re-entry; and downhole splitter system. Because splitter wells share the same surface location and casing, the process takes less time and materials than drilling two conventional wells. An estimation of the drilling time saved for the splitter well is 8-10 days for each additional well drilled. 7 figs.
