Underbalanced drilling operations reduce the hydrostatic pressure of the drilling fluid column so that the pressure in the wellbore is less than the formation pressure. It is defined as the practice of drilling a well with the wellbore fluid gradient less than the natural formation gradient. It differs from conventional drilling in that the bottomhole circulating pressure is lower than the formation pressure, thereby permitting the well to flow while drilling proceeds. Underbalanced drilling technology is a valuable method for minimizing formation invasion related problems. Most of the underbalanced drilling applications are conducted through the use of coiled tubing systems.
