Permeability modeling is the most challenging task in anyReservoir Characterization Work

Over 90% of the time consumed during iteration processbetween Static & Dynamic models is due to

Permeability Model Adjustment

ADNOC has build its own permeability prediction tool thatshowed encourage results

Permeability-Porosity Relationship, Case Example

14,792 data set 265,772 data set

“PERM42”, has been designed to use from 1 to 6 logs parameters for data training to predict permeability’s for uncored depth intervals.

In the following example, only Porosity and Sw logs as input data were used.

Core & Predicted Permeability’s Distribution Trend

Core & Predicted Permeability’s per Well, Case Example

“PERM42”, shall honor all intervals that have core permeability measured values, and it would generate permeability values for uncored interval, while respecting barriers and high permeability streaks.
