EMW reduction when POOH

Additional margin above pore pressure

Typical Trip Margins

  • Normal operations: 0.2-0.5 ppg
  • High-pressure zones: 0.5-1.0 ppg
  • Marginal wells: Use swab calculations

Formula Reference

Trip Margin = MW - Pore Pressure - Safety Factor EMW_swab = MW - Swab_Effect Safe Condition: EMW_swab > Pore Pressure + Safety Factor Pressure Margin = (MW - Pp) x 0.052 x TVD
