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

摘要

Drilling on the Troll Oil field has been challenged by the needrnfor long and extensive horizontal hole sections while strictlyrncontrolling true vertical depth.rnThe horizontal reach has been extended from initiallyrnabout 800 meters to more than 4,400 m in a single well borernusing the latest generation of Rotary Steerable Systems. At thernsame time, multilateral drilling technology has become arnstandardized application on Troll with up to four reservoirrnsections completed per well.
