Summary: PWRI at fracturing conditions

• Compare coupled and uncoupled geomechanical and reservoir simulations
• Uncoupled simulations fracture permeability = f(p)
• Coupled simulations account for poro- and thermo-elastic stress changes
  and fracture containment
  
  
   

  An individual fall-off match:

  1.Both good match on linear scale
  2.Both good match on log scale
  3.Flow regime behavior both satisfactory

  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
   

  General History match:

  1.Coupled model can match increasing Pinj with time Smin = f(p, T, b.c.)
  2.Coupled model can predict increasing fracturing pressure with time
  3.Coupled model has ability to forecast performance if calibrated properly

  •Coupled model gives correct fracture shape confirmed by PLT
  •Coupled model gives different fracture length and conductivity profile
  •Coupled model can investigate fracture containment
