2/2/2024 0 Comments K3 directional drillingAn indication of the future of directional drilling through autonomous downhole tools and remote operating centres is discussed. The notion of the “telescoping” casing/hole design is discussed.Ī brief history of the methods of directional drilling leads to a discussion on the differences between geometric wellbore placement and geological wellbore placement (geo-steering) and the benefits that this has had on well and field productivity. The functions of casing and cementing are discussed and the basic principles of casing depth selection explained. The use of drilling fluids as the primary means of controlling wellbore pressure and the use of the BOP as a secondary means of control is described and explained. The origins of wellbore pressure are explained.
