Since drilling of the first oil well over a century ago, fluid circulation must be stopped every time drill pipe connection. Circulation stopping represents one of the main reasons for typical drilling problems related to wellbore pressure. A continuous circulation technology is an innovative drilling method used to maintain the circulation of drilling fluid into the well during making and breaking drill pipe connections. The system contains a manifold connected to drill string that enables safe diversion, and subs installed at the top of each drill pipe stand, providing two independent flows. It can optimize drilling operations and overcome wellbore issues caused by interruption of fluid.
