LPR N Valve Standard Downhole Tester Valve For Drill Stem Testing Valve

The LPR N Tester Valve is a standard tester valve in drill stem testing service. The N valve is a full-opening, annulus pressure-operated valve. The full bore design of tester valve permits measuring multiple closed-in pressures in cased holes where pipe manipulation is restricted and a full-opening string is required.

The nitrogen chamber of LPR N Valve is charged at the surface to a selected pressure determined by surface temperature and bottomhole temperature and 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 help ensure that the formations and downhole equipment are protected from excessive pressure build up.
