Underbalanced Drilling

Description:

This presentation covers the underbalanced drilling method, which is defined as the practice of drilling a well with the wellbore fluid gradient less than the natural formation gradient. Besides minimizing lost circulation and increasing the penetration rate, this technique has a widely recognized benefit of minimizing the damage caused by invasion of drilling fluid into the formation. Different underbalanced drilling equipment and techniques are discussed under this topic. The underbalanced well classification system used by the industry and several case studies are also covered in this presentation.
