Abstract
In accordance with an illustrative embodiment of the present invention, a circulating valve for use in sand control and related well operations includes a mandrel that can be rotated in a housing after a weight-responsive clutch is released. As the mandrel is rotated to the right, a reverse lead groove system engaged by a pawl causes a valve sleeve element to shuttle down and up between positions closing and opening a flow path between the annulus above a packer and a zone in the well below the packer.
