SurgeMOD iconSurgeMOD - surge pressure prediction

Moving a pipe in the hole is accompanied by a displacement of the mud, leading to pressure variations. The accurate prediction of surge / swab pressure is of great importance in wells where the pressure must be maintained within narrow limits to ensure trouble-free drilling and completion operation.
SurgeMOD is developed to design and analyze the complex downhole hydraulics when running casing or making a trip.

  • Pipe end: closed / open / auto-fill / bit / circulation sub
  • Optimal trip speed design
  • Surge pressure for given pipe speed
  • Sensitivity analysis on tripping speed
  • Multiple weak zones
  • Pressure drop cross float shoe
  • Bingham plastic or power law fluids
  • Allowable flow rate after the casing is set
  • Tripping animation
  • MS Word report
  • US oil field, SI and customized units
