Simulation Model Setup

• Grid --gt 70 x 80 x 3(2)
• Grid orientation?
• PVT and petrophysical data
• Dual porosity
• Geological input
• Oil production constraint
• Injectors, producers...

Conclusions..

• Fracture enhancement is preferred to grid
  orientation
• It is important to determine the angles and
  distances of the Injectors and Producers Relative
  to the Predominant Fractures
