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.
