The CANSCO AS Annular Blowout Preventer (BOP) is built for surface (land, jack-up, platform etc.) applications worldwide and comes in a range of well bore sizes and working pressure ratings to suit the full range of well construction, completion, workover and intervention activities. It’s simple and reliable construction makes the AS Annular BOP ideal for operating in rugged, harsh environments and in extreme temperatures.

The AS packing element, energised by hydraulic operating pressure, can achieve complete shut-off on well open-hole, and well annulus shut-off on virtually all profiles of Kelly, drill string pipe and collar, casing and tubing string, tool joints and wireline. In addition the flexibility of the AS packing element allows well annulus shut-off to be maintained as the string profile changes dynamically, permitting stripping of drill string under well pressure.
