1.2 Drilling Program - Initial Information
De ning well objectives
• exploration
• appraisal
• development / production
Obtaining Consent
• permission from relevant authorities
Collection of data
• well pressure data, seismic etc.
Establish subsurface pressure regimes
• differing pressure regimes
Establish formation fracture gradients
• forecast of fracture gradients or effective casing design
Well Plan Basics
Porosity
• Sedimentary rock has pores (small openings)
Permeability
• Connected pores allow uid to ow
Pore Pressure
• Normal, abnormal or subnormal pore uid pressure
Rock Stress
• Force imposed to the rock
Balance
• Mud weight must balance pore pressure and rock stress
