Abstract: A counter including a housing disposed about a tubular creating a space therebetween, a piston disposed in the space and responsive to pressure up events in the tubular to compress a transfer chamber, a supply chamber fluidly attached to the transfer chamber; a trigger chamber fluidly attached to the transfer chamber wherein sequential pressure events cause the piston to move fluid from the supply chamber to the trigger chamber. A counter including a fluid incrementing configuration, an activation member in fluid force communication with the fluid incrementing configuration, the activation member having a first position where a fluid port is blocked and a second position where the fluid port is unblocked, the fluid port being fluid pressure connected to a tool to be actuated when the activation member is in the second position.

Abstract: A testable indexing plug includes a body having an outer surface, an inner surface defining a flow path, a first end, a second end, and an intermediate portion extending between the first end and the second end. A valve chamber extends from the first end into the intermediate portion. A valve member is arranged in the valve chamber. The valve member includes a first end portion, a second end portion including an opening, and an intermediate section including one or more ports fluidically connected with the opening. An indexing system shifts the valve member between a first position, wherein the one or more ports are arranged in the valve chamber and a second position, wherein the one or more ports are exposed outside of the valve chamber following a defined number of pressure applications to the valve member.
