This paper descnbes strategies and techniques employed to extend the drilling reach in the Gullfaks field, offshore Norway. Field development plans were originally based upon deviated wells drilled to a maximum inclination of 60°and a maximum displacement of 3 kID. Emerging horizontal drilling techniques encouraged a reevaluation of these field development plans. These techniques are now being implemented to increase the inclination and extend the reach to 5 kID in support of the revised plan. The early success achieved has urged further consideration of extended-reach drilling to as much as 10 kID.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
