Abstract
A reverse cementing apparatus having a reverse cementing body with an internal bore, the reverse cementing body being coupleable to the downhole end of a casing pipe. The apparatus may further have a valve actuable from a closed to an open configuration, the closed configuration obstructing flow of fluid through the internal bore of the reverse cementing body. The valve may be configured to obstruct flow in an uphole direction during deployment but permit flow in the downhole direction. The apparatus further includes a port provided extending through a wall of the reverse cementing valve body from the internal bore to external the reverse cementing body, a fluid communication channel extending from the port to the internal bore. An actuable barrier member may be provided which is actuable to a closed position obstructing flow of fluid through the port upon actuation.
