Directional Drilling with Casing
SPE/IADC Drilling Conference, 2003Abstract Drilling with casing has proven to be an effective method of reducing drilling costs and solving drilling problems. Most of the current Casing Drilling* activity is focused on drilling vertical wells, but interest in directional wells is increasing as the benefits of Casing Drilling in straight holes are demonstrated.

Vertical Drilling Technology: A Milestone in Directional Drilling
Proceedings of SPE/IADC Drilling Conference, 1993ABSTRACT The Continental Deep Drilling Program of the Federal Republic of Germany (KTB) is a fundamental research project to investigate the physical and chemical conditions and processes in the deep continental crust. To meet the geoscientific goals, it is necessary to drill an ultra deep borehole with a target depth of 10000 m.

Direct-push drilling technology includes methods that advance a drill by pushing, hammering, or vibrating. Although these methods do not meet the proper definition of drilling, they do achieve the same result—a borehole and, if applicable, a core. Direct-push drilling tools do not remove cuttings from the hole.
