RESERVOIR QUALITY INDEX – RQI
Porosity and permeability data are key to assessment of reserves, potential production, and ultimate recovery. The combination of (phi) and k data in terms of reservoir quality index (RQI) provides a convenient starting point.
The Reservoir Quality Index measures reservoir transmissibility and was derived as:
The Reservoir Quality Index is used to estimate Swi in wells using k and Phi logs for formations like the example:
