Multilateral system creates cemented junction in a single trip

摘要

Technology can access nearby additional reserves while maintaining original wellbore production. A single-trip multilateral system, Weatherford's OneTrip StarBurst technology creates a Technology Advancement for Multilaterals Level 4 cemented junction with fullbore liner access to the lateral bore. This represents an advancement to the conventional StarBurst system that required three trips for installation. StarBurst systems, which can be used for new development drilling and reentries, provide access to additional reserves while maintaining original wellbore production. The technology won the drilling tools category of Hart Energy's 2009 Meritorious Awards for Engineering Innovation. Since its introduction, the system has brought simplicity to multilateral solutions. "Since the mid-1990s, attempts have been made to create multilateral systems that provide a maximum number of combined features and options," said Cliff Hogg, Weatherford's global product line manager for reentry systems. However, in an attempt to create these maximum-flexibility multilateral systems, the industry ended up with solutions that were impractical for a variety of reasons.
