permeabilities that find their way into the static and dynamic models.
What happens in practice is that during the history-matching process in
the simulator, the permeabilities may be adjusted either globally or near
certain wells in order to make the predicted flow rates match the produc-
tion data.

Exercise 3.1. Full Evaluation of the Test1 Well

Use the data in Appendix 2 to:

1. Revise your net sand discrimination criteria if necessary
2. Calibrate the density log against core porosity. Assume a net effective
stress of 2000psi.
3. Derive a poroperm relationship
4. Derive revised values of m and n to use
5. Recalculate the sums and averages and additionally calculate average
permeabilities (using arithmetic, geometric, and harmonic averaging)
and k*h
6. Calculate the total equivalent hydraulic conductivity (EHC) (thickness
*porosity*S h ) and compare with your quicklook results.
