Permeability modeling
Permeability is one of the key parameters necessary for reservoir characterization, and for accurately predicting the fluid flow in a reservoir. It is a measure of the capacity of a rock to transmit a fluid (e.g. gas, oil or water). It can be determined by direct measurement on core samples in the laboratory, or by well test interpretation.
Since permeability is a rock property which cannot be obtained directly from wireline logs, it is common practice to use correlations with other rock properties that can be measured by logs. For this reason, JewelSuite offers a function based permeability modeling approach, with two consecutive workflows in the Permeability strip (model > Permeability). These are:
- Permeability Function Modeling In this workflow, you define permeability functions per facies class. You use this function model as input to your permeability property model.
- Permeability Property Modeling In this workflow, you use the permeability function model to populate your 3D grid with permeability properties. You can use these 3D grid properties as input to your dynamic simulation.
In JewelSuite, permeability modeling can also be indirectly linked to volumetric calculations, via saturation modeling. See About permeability modeling for more on this.
