5" LPR- N Valve DST Tools
Drill stem testing tester valve LPR - N valve
The LPR-NTesterValve is afull-opening, annulus pressure-operated valve.It permits measuring multi pleclosed-in
pressures incased holes where pipe manipulation is restricted and afull-opening string is required. 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.
