A Quadruple-Porosity Model for Consistent Petrophysical Evaluation of Naturally Fractured Vuggy Reservoirs

What is it about?

The work discusses the significance of reliable fluid saturation estimation. We propose a new quadruple-porosity model for the accurate determination of the porosity exponent in naturally fractured vuggy reservoirs. We establish new porosity-porosity exponent relations that account for pore-structure type variations.

Why is it important?

The proposed quadruple-porosity model would help to ensure accurate estimation of the porosity exponent and water saturation, which is critical for reliable formation petrophysical evaluation in naturally fractured vuggy carbonate reservoirs.
