The challenge of porting the Slim Hole technology concept to deep offshore applications is to adapt to floating support, and solve specific problems such as heave compensation, to allow an accurate control of the weight on bit as well as designing a new riser system. Different alternatives for drilling equipments to achieve the challenges and to reduce the size of the vessels suitable for Slim Hole drilling are reviewed. The ability to adapt Slim Hole drilling will allow oil exploration to 2,000 m and beyond, with a significant reduction of costs compared to conventional exploration drilling.
