The concept of drilling and casing the hole in the same time is, of course, valuable by combining two time consuming processes. So the main purpose of Casing Drilling, or Casing while Drilling (CwD), is to eliminate classic casing runs and isolate formations while drilling. By using Standard casing string instead of conventional drill string, […]

Casing is a significant component of the oil and gas well drilling process. It is used to protect the wellbore from collapsing, to prevent fluid migration between rock formations, and to provide a stable platform for drilling. Casing is generally made of steel and is run into the wellbore and cemented in place. Different types […]

The casing pipe is mandatory in drilling opera􀆟ons as it has a lot of casingfunc􀆟ons to prevent cave-in of unconsolidated forma􀆟ons, isolate problem zones,and many more. As men􀆟oned before in our casing design guide, the selec􀆟on ofcasing depends on many factors. Here in this ar􀆟cle, we shall learn everythingabout the best drilling prac􀆟ces for casing […]
