What is BOP stack In oil And Gas?

Answer 1

Blowout Preventers (BOPs) are a configuration of valves and piping used to ensure pressure control of a well. A typical BOP stack might consist of one to six ram-type preventers and one or two annular-type preventers. A typical configuration has the ram preventers on the bottom and the annular preventers at the top. The configuration of the stack preventers is optimized to provide maximum pressure control and safety in the event of a well control incident. It is common to have an annular preventer or two on top of the stack since annulars can be closed over a wide range of tubular sizes and the openhole, but annular preventers are typically not rated for pressures as high as ram preventers. The BOP stack also includes various spools, adapters and piping connections to permit the circulation of wellbore fluids under pressure in the event of a well control incident.
