A valve collar for a downhole packer includes a flow path. The flow path includes an opening valve and closing valve. The valve collar further includes a lockout valve piston. The lockout valve piston is positioned such that in an unset position, the flow path is open and in a set position, the flow path is blocked by the lockout valve piston. The lockout valve piston may be adapted to be shifted from the unset position to the set position by a pressure spike inside the valve collar. The lockout valve piston may be held in the unset position by a temporary restraint.

Low fluid level valve

An apparatus deploys on a casing and has a toe with first and second ports for communicating with a wellbore. A packing element between the ports is actuatable to isolate portions of the wellbore. The toe operates in a first condition for run-in to prevent fluid communication through the ports, although washdown can flow through a toe port. Once installed, the toe operates in a second condition for cementation when the first plug is deployed to the toe. In this condition, the toe actuates the packing element, permits fluid communication through the first port, and prevents fluid communication through the second port. After cementation, the toe operates in a third condition for fracture and completion operations when the second plug is deployed. The toe in this condition prevents fluid communication through the first port, but permits fluid communication through the second port downhole of the set packing element.
