Internal Pressure Operated Circulating Valve Open Hole IPO for Well Testing

Introduction of IPO Circulating valve

The IPO circulating valve is the Internal Pressure Operated Circulating Valve used in open hole drill stem testing service. The IPO valve 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.

Feature and benefits

* The IPO valve requires no string manipulation to operate tool.

* The IPO Valve permits passage of wire line tools through full opening bore.

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.
