Troll Oil Drilling; Step Changes through Application of Front End Technology

摘要

Drilling on the Troll Oil field has been challenged by the need for long and extensive horizontal hole sections while strictly controlling true vertical depth. The horizontal reach has been extended from initially about 800 meters to more than 4,400 m in a single well bore using the latest generation of Rotary Steerable Systems. At the same time, multilateral drilling technology has become a standardized application on Troll with up to four reservoir sections completed per well.
