Simultaneous Drill and Case Technology - Case Histories, Status and Options for Further Development

摘要

Drilling liner technology has become a standard for enteringdepleted reservoirs in areas of the North Sea and SoutheastAsia and interest continues to increase for use of drilling linersto overcome other drilling problems. Marketing analyses haveshown that further development of drilling liner technology andapplication has been rated with high priority.Based on experience gathered during the last five years, thispaper covers possible further Drilling Liner applications, newchallenges, and requirements for new systems. "Drill and Case"systems will be introduced and benefits shown by means ofcase histories of jobs carried out in Norway and Indonesia.
