SafeVision Training

Most drilling problems can be avoided by keeping the pressure inside the wellbore within what is called the mud weight window. On one hand the knowledge of the pore, collapse or fracture pressures can be estimated with some degree of accuracy; on the other hand knowing the pressure profile inside the wellbore is not an easy task.

In the past wells were drilled with a very comfortable mud weight window, which led to many assumptions and generalizations. Often very little attention was paid to the many subtle pressure relationships inside the wellbore. Knowledge of the mud weight at surface was deemed enough.

With wells being drilled in more challenging environments, the mud weight window has been reduced significantly. For most wells being drilled today it is critical to know, as accurately as possible, the pressure along the entire annulus. This level of complexity now forces us to look beyond what can be done with rules of thumb or by hand calculations.
