AirLock Casing Buoyancy System

The AirLock™ system facilitates landing casing strings in horizontal wells, at nominal cost and without altering casing and cementing operations. Unlike conventional float shoe systems, the unique AirLock seal allows the vertical casing section to be filled with fluid, while the lateral section remains air-filled and buoyant. The enhanced buoyancy reduces sliding friction up to 50%, while the enhanced weight of the vertical section provides the force needed to push the string all the way to the toe of the well. www.ncsmultistage.com
