Cased Hole Internal Pressure operated Circulating Valve / DST IPO Circulating Valve
The IPO circulating valve is the Internal Pressure operated circulating valve, the tool allows circulation through the work string before trip-out and serves as a drain during trip-out. It can be run in cased holes or open holes and maintains a full bore through the tool.
The IPO circulating valve is used in the below situations:
When a full opening string is needed.
When redundant backup to annulus pressure operated circulating valves is needed.
When a limited amount of annulus-pump pressure is available to operate annulus pressure tools.
Operation of IPO Circulating Valve
The IPO circulating valve is operated by internal pressure(500-10000psi above hydrostatic).Pressure required to operate the tool is determined by shear pins, which hold the sliding valve in the closed position. To open the valve, tubing pressure is increased to a pressure above annulus hydrostatic equal to the shear value of the shear pins. Once operated, the IPO Circulating valve locks open.
