You don’t need a big rig! • Screen the opportunities • Identify constraints • Engineer feasibility to spec “What it will take” • Latest technological innovations, teamwork www.MerlinERD.com
Fundamentals 3 Critical Priorities for High Angle Wells Hole Cleaning Hole Cleaning Hole Cleaning www.MerlinERD.com
Hole Cleaning Regimes www.MerlinERD.com
Drilling Loads • BHA & DP weight = > Drag • Stiffness? • Contact Area? (think 1 st principles) www.MerlinERD.com
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? www.MerlinERD.com
