PACKER INFLATION PRESSURE FORMULA For Inflation with Air or Nitrogen Gas
G = Inflation pressure at gauge (PSI) DP = Depth to top of packer (feet) DW = Depth to static water level in well (feet) Sp = Unconfined packer pressure rating for the well size (PSI) PP = Injection pump pressure (PSI)
1 To calculate Packer Inflation Pressure for a withdraw test (pump out):
G = [ (DP - DW) x .43 ] + Sp + [ (DP - DW) x .43 x .2 ]
NOTE: This total must not exceed confined packer pressure rating for the well size.
2 To calculate Packer Inflation Pressure for an injection test (pump in):
G = [ (DP x PSI per foot of Injected Fluid*) + Sp + PP ] x 1.1 *.43 for Water or .6 for grout
NOTE: This total must not exceed confined packer pressure rating plus (DP - DW) x .43
