This paper reviews the new Euroslim drilling system which allows deep penetration of small diameter exploration and production wells. The Euroslim approach is an optimized conventional rotary drilling technique that allows continuous coring of the zone of interest. The initial project set the requirements of power transmission and hydraulic optimization to drill 4 3/4 inch holes to 3,500 meters with a single drill pipe size. A second drill string has now been designed to reach 4,000 meters with hole sizes ranging from 3 inches to 3 11/32 inches. This paper reviews the specifications of the drill pipe, core barrels, drill rig, stabilizers, drill bits, and deviation tools. A cost benefit analysis is also provided comparing the slim-bore drilling to conventional drilling.
