  • relationship between the Consolidation Parameter porosity and aspect ratio in microporous carbonate rocks
    Journal of Applied Geophysics, 2015
    Co-Authors: Marco Ceia, Roseane M Missagia, Irineu Lima Neto, Nathaly L Archilha
    Abstract:

    Abstract The estimation of dry bulk modulus is required for the successful application of the Biot–Gassmann theory to forecast fluid changes within a reservoir. The Pride model is one of the several models described in the literature for predicting the dry elastic moduli of rocks. However, the accuracy of the Pride model depends on the estimation of the Consolidation Parameter. In this paper, the Consolidation Parameter was estimated using the pore stiffness, mineral bulk modulus and porosity. That approach allowed calculating the dry bulk modulus of a set of microporous carbonate rocks according to the Pride model and compare those estimates to the results obtained using the elastic velocities. The change in the Consolidation Parameter over a range of pressures suggests that the relationship between this Parameter and the unconfined porosity increases at high effective pressure. Statistical analyses of the distribution of those Consolidation Parameter values were performed to verify how the effective pressure influences the mean value and variance. Mean pore aspect ratios were estimated using Kuster–Toksoz methodology to establish a relationship with the Consolidation Parameter and the unconfined porosity. Such relationship also accounts for pressure-dependence within the studied pressure range. Although only 20 samples were analyzed, those studies can contribute to advise the estimation of the Consolidation Parameter in this type of carbonate rocks.

    Abstract:

    The estimation of dry bulk modulus is determinant for the success of the application of Biot-Gassmann theory to forecast fluid changes within a reservoir. The Pride model is one of the various models described in literature for predicting the dry elastic moduli of rocks. However, that model depends on the Consolidation Parameter and its appropriate choice implies in the accuracy of that model. In this paper, the Consolidation Parameter is estimated in microporous carbonate rocks. Mean aspect ratios were estimated using Kuster-Toksoz methodology and aided to establish a relationship between the Consolidation Parameter, the unconfined porosity and the aspect ratio. Those studies can advise the estimation of the Consolidation Parameter in carbonate rocks, especially when compressional and shear velocities are unknown.

In this paper, two methods for estimating the Consolidation Parameter are tested and compared in microporous carbonate rocks. The observation of how this Parameter changes as pressure increases allowed the proposal of a relationship that relates the Consolidation Parameter and the unconfined porosity to be used at high effective pressure.
