Procedures When Discovered During1)
Exploration/Access

• Obtain cores and/or image logs in all early wells
• Predict natural fracture distributions
• Select optimum well locations and well paths
• Determine and map in situ stress from breakouts,
  etc..
• Determine fractured reservoir type
• Evaluate reserves, variability, and risk

8
Procedures When Discovered During2) Primary
Recovery/Production

• Plan static data collection wells
• Perform multiple well tests
• Model fracture system and in situ stress and
  correlate with dynamic data
• Determine directional permeability vectors
• Correlate fracture directions, in situ stress,
  and directional permeability
• Refine reservoir simulations using fractures

9
Procedures When Discovered During3)
Secondary Recovery/Harvest

• Re-evaluate flood patterns
• Evaluate water production in terms of fractures
• Model in situ stress across the field
• Infer characteristics of the fracture system from
  dynamic data
• Re-evaluate reservoir simulations to include
  fracture anisotropy
• Revise predicted recovery factor (down)
