This paper discusses the experimental evaluation of various proposed well control techniques which may be implemented when normal kill operations are delayed. Two 6000-ft wells, one containing the flow geometry present in a surface blowout preventer (BOP) stack and the other modeling the flow geometry of a subsea BOP stack in 3000 ft. of water, were used to evaluate the constant drill pipe pressure method and the static and dynamic volumetric methods that can be employed when a meaningful drill pipe pressure is not available. It was found that any of the three methods could be used to maintain an acceptable bottom hole pressure in a surface BOP system with a uniform annular geometry. However, the static volumetric method generally resulted in a decreasing bottom hole pressure once gas reaches the subsea choke line and is not recommended for deep-water floating drilling operations.
