The LPR-N Valve is a full-opening, annulus pressure-operated valve, which is the main test valve for the drill stem testing operation in cased hole

5" LPR-N Valve, working pressure: 15000psi


Introduction


The Tester valve is a full-opening, annulus pressure operated tool. With applied pressure, the tool can be locked open and then returned to the normal operating sequence at any time. The ball valve operates independently of pressure changes from operations such as acidizing and fracturing. This gives theTester valve greater compatibility and flexibility with other tools in the string.It is fully balanced to annulus pressure and will remain in the closed position while tripping in hole. Operation of the LPR-N valve insensitive to tubing pressure changes


The nitrogen chamber is charged at the surface to a selected pressure determined by surface temperature and

bottom hole temperature and pressure.

If the intended test requires a permanent packer that uses a stinger mandrel or seal nipple,a variety of Halliburton

by pass tools are available,depending on field application,to help ensure that the formations and downhole

equipment are protected from excessive pressure build up.

Features and Benefits

•The ball valve operates independently of internal pressure changes,like with acidizing or fracturing operations.

•Drastic temperature changes,like inacidizing operations,have little affecton the tool.

•Advanced materials and processes provide a uniquemetal-to-metal seal for exceptionalgas-holding capabilities.

•The valve has been through an extensive 5-day qualification testing at 400°Fand 15,000-psi burstand collapse

pressures.

•An open-in feature allows the operator to run the valve in the hole with the ball valve opened orclosed.

•Adouble nitrogen chamber can be added to the valve for use in deep,hot,high pressure wells to reduce the

operating pressure
