Advances in engineering and technology have developed new blowout preventers, specialized surface fluids control equipment and well control techniques for under balanced drilling. The new technology makes under balanced drilling faster, safer and less expensive. These devices and techniques reduce the risk of blowouts, when drilling with air, gas or gas cut drilling fluids while producing the zone of interest. Improved penetration rates, increased bit life, drilling cost reduction and the prevention of formation damage are benefits of drilling under balanced and specially designed BOP stacks and well control products are necessary to ensure success. The following outlines the content of this paper: History and Development of Rotating Well Control for Under Balanced Drilling; Rotating BOP and Under Balanced Drilling BOP Stack, including Land Based Operations and Offshore Operations; Design and Technical Review; Safety; Operating Considerations; Field History, An Operator`s Perspective; and Advantages.
