The atmospheric collar is ideal for casing in horizontal wells, where reaching TD can be difficult.
This deployment tool has been designed to aid in running casing to deeper depths by reducing friction in the horizontal section of the well. The atmospheric collar features an internal wiper plug with a shear plug that isolates fluid above and air below down to the float equipment. This allows casing to float to the bottom, significantly reducing the weight in the horizontal section.
