Brief of 3 7/8" LPR-N Valve

 

The 3 7/8" LPR - N Valve is a kind of full opening tester valve used in slim hole drill stem tesing operation.

The LPR-N Valve is  annulus pressure-operated tester valve to measure multiple closed-in pressures  where pipe manipulation is restricted and a full-opening string is required

 

General LPR-N Valve Operations


As the LPR-N Tester Valve is run into the well, the ball valve of the tester valve can either set up to be in the open or closed position. The power section controls the ball valve mechanism. The power section has a moving piston with one side exposed to hydrostatic pressure and the other side exposed to pressurized nitrogen.


After the packer has been set, pressure is applied to the annulus, moving the piston downward to pull the
ball into the open position. Releasing annulus pressure allows the pressurized nitrogen to return the
piston upward to close the ball valve.


The nitrogen chamber is charged at the surface to a predetermined pressure depending upon surface
temperature, bottomhole temperature, and hydrostatic pressure at testing depth. This charging pressure
gives the tool the optimum volume for compression in the nitrogen chamber when the tool arrives at
testing depth. These values do not have to be exact because the floating piston compensates for small
inaccuracies
