Underbalanced drilling

Underbalanced drilling aims at maintaining the drilling fluid at a pressure lower than that of the surrounding formation. It offers several advantages as compared to conventional drilling methods, as well as a set of unique operational challenges.

Air Liquide offers a range of industrial and specialty gas solutions to help maximize both safety and efficiency in underbalanced drilling operations, from high pressure nitrogen production technologies for inerting and well injection to stable isotope pure gases and gas mixtures designed to maximize information obtained from wells. Our turnkey offer allows us to optimize our service quality and boost our customers’ performance while minimizing complexity and risk.



Air Liquide offers a full range of equipment for industrial and specialty gases.
