4 Problem Definition <10% Oil Recovery in 50 years!
Complex fracture system Huge Kfx/Kfy Ratio (17,000md/100md !) Conventional Waterfloding???

5 Field Production Indicator…….

7 Simulation Model Setup
0.25miles 20w 29w 4w 14w 11w FLOYD 7w Grid --> 70 x 80 x 3(*2) Grid orientation? PVT and petrophysical data Dual porosity Geological input Oil production constraint Injectors, producers... 23 1C 21 33 25i 29 27 7w DA1 17 ET3 ET2 ET1

11 80 Acres Spacing 7w P1 P2 P3 P4 P5 P7 P6

12 120 Acres Spacing 7w P1 P2 P3 P4 P5 P7 P6

13 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
