• Similarities and contrasts between conventional drilling, UBD and MPD
• The operating window – planning vs real
• Recognizing an MPD candidate well – technical/economical/safety value
• Recognized variants of MPD
  • HSE
  • Single Annular Point Constant Pressure – Pivot Point - CBHP
  • Mud Cap
  • Dual Gradient
  • Continuous Flow
