2. Over View June 2002-June 2003
In Progress

3. Summary
The intention of this project is to assess the effectiveness of matching the post Frac test data, in order to match a Beta for the proppant size utilised in the frac
A total of six wells have been matched, out of which three are presented here
Three examples are presented for the following proppant sizes.
20/40 single phase
16/20 multi-phase (oil and gas)
12/18 single phase

4. Modeling Non Darcy Effects in a Fracture (Theoretical Equ)
For two phase non-Darcy effects, a review of the literature suggests the following the relationship:

5. Example-1 20/40 Proppant, at 4 Lb/ft2 (Top structure Map)

6. Fracture Profiles input 20/40 Proppant, Conc=4 Lb/ft2

7. WellWhiz Output (20/40)

8. Multi-Frac Horizontal Well (Oil and Gas)

9. Proppant: 16/20, 3 Lb/ft2 (Alpha=48,800, n1=0.50, n2=5.5)

10. Example-3 Single(?) Phase Gas 12/18 at 2 Lb/ft2

11. Net Pressure Match

12. Frac Geometry

13. Proppant concentration

14. WellWhiz Match 12/18 Proppant (2 Lb/ft2)

15. Summary of Field Beta

16. Condensate Modelling
Detailed presentation will be made tomorrow afternoon to highlight:
The effects of condensate on well productivity
Can proppant design help in reducing the effects of condensate banking around the fracture?

17. Next Years Prog July 2003-June 2004
