Briefly Introduction   

The Pressure Operated tester valve is a full- opening, annulus pressure-operated valve. It measures multiple closed-in pressures in cased holes where pipe manipulation is restricted and a full-opening string is required. The nitrogen chamber is charged at the surface to a selected pressure determined by surface temperature, bottomhole temperature, and bottomhole pressure. If the intended test requires a permanent packer that uses a stinger mandrel or seal nipple, a variety of bypass tools are available, depending on field application, to help ensure that the formations and downhole equipment are protected from excessive pressure buildup.

Features and Benefits
• The ball valve operates independently of internal pressure changes, such as with acidizing or fracturingoperations.
• Advancedmaterials and processes provide a unique metal-to-metal seat for exceptionalgas-holding capabilities.
• The Pressure operated tester valve (LPR-N valve) has been through an extensive five-day qualification testingat 400°F and15,000 psi burst and collapse pressures.
• An open-in feature allows the operator to run the Pressure Poerated tester in the hole with the ball valve opened orclosed.
• Fluids can bespotted or circulated through the PRESSURE OPERATED tester  (LPR-N valve)with the packer unseated.

• A double nitrogenchamber can be added to the Pressure operated tester for use in deep, hot,high-pressure wells to reduce the operating pressure.
