– BD04A: 36,768 ft (11,207m) departure, 36 days

  • Apache, West Cycad, Australia – STANDARD JACK-UP:

– 22,500 ft md, 5200ft tvd, 29 days D&C

  • Exxon, California

– 18,000 with 800 hp rig, 15 years ago!! You don’t need a big rig!

  • Screen the opportunities
  • Identify constraints
  • Engineer feasibility to spec “What it will take”
  • Latest technological innovations, teamwork

Drilling Loads

  • BHA & DP weight = > Drag
  • Stiffness?
  • Contact Area? (think 1st principles)

Critical Success Factors

How close to the edge of the cliff are you? How can you tell? Offset Data What is different Modelling (guess) When are extra actions justified? New team Change in design (DP, fluid, inc, azi) Actions prioritised for risks & consequences – No contingencies?
