Investigations into the coiled tubing partial underbalanced drilling (CT-PUBD) technique for drilling hard formations

Abstract To improve the rate of penetration (ROP) in drilling deep and hard formations, this paper proposes a new drilling method called coiled tubing partial underbalanced drilling (CT-PUBD). As a preliminary investigation into the new drilling method, this paper presents predictions of hole cleani...
