The LPR N 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 Halliburton bypass tools are available, depending on field application, to 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 fracturing operations.
Drastic temperature changes, such as in acidizing operations, have little effect on the tool.
Advanced materials and processes provide a unique metal-to-metal seat for exceptional gas-holding capabilities.
The LPR N tester valve has been through an extensive 5-day qualification testing at 400'F and 15,000 psi burst and collapse pressures.
An open feature allows the operator to run the LPR N tester in the hole with the ball valve opened or closed.
Fluids can be spotted or circulated through the LPR N tester with the packer unseated.
A double nitrogen chamber can be added to the LPR N for use in deep, hot, high-pressure wells to reduce the operating pressure.
