Open hole drill stem testing
5" x 10000psi Internal Pressure operated IPO Circulating Valve
Internal Pressure operated circulating valve

The IPO circulating valve is used in the following 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.

Feature and benefits

Requires no string manipulation to operate tool.

Permits passage of wire line tools through full opening bore.

Operation

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.
