Examples described herein provide a computer-implemented method for deriving textural properties of a reservoir formation. The method includes acquiring multi-frequency dielectric data (ε). The method further includes applying a dielectric mixing model between different fluid phases to generate an effective fluid permittivity (ε) by mixing the permittivity of water and hydrocarbon fluids. The method further includes applying the dielectric mixing model between the effective fluid permittivity (ε) and a matrix permittivity (ε). The method further includes minimizing a difference between a measured dielectric response and the dielectric mixing model by optimizing model parameters. The method further includes computing a cementation exponent (m) and a saturation exponent (n) from the multi-frequency dielectric data (ε). The method further includes estimating a formation property based at least in part on the cementation exponent (m) and the saturation exponent (n). A wellbore operation is controlled based at least in part on the formation property.

A method of estimating a material mechanical property of a porous material, for an application or objective with a specific application frequency and application strain amplitude, includes estimating an application frequency and an application strain amplitude for use in a targeted application or objective, and constructing a frequency transfer function relating the material mechanical property to measurement frequencies, the measurement frequency range including a measurement frequency different from the application frequency. The method also includes constructing a strain amplitude transfer function relating the material mechanical property at the measurement strain amplitude and the material mechanical property at the application strain amplitude, the measurement strain amplitude different from the application strain amplitude, deriving the material mechanical property from the frequency transfer function using the application frequency, and predicting the material mechanical property from the strain amplitude transformation function using the derived material mechanical property.

Estimation of objective driven porous material mechanical properties

Methods and apparatus for evaluation of an earth formation including evaluating a core sample obtained from the formation. Methods include using a change in measurements of at least one stress parameter of the core sample, such as radial strain, axial stress, and acoustic emission counts, over time responsive to an applied stress to estimate imminent rock failure in the core sample. This may include estimating the imminent rock failure using differences between portions of a curve generated based on the measurements. A method employing calculating a rate of change between a plurality of measurements of at least one stress parameter of the core sample over time responsive to an applied stress; and determining a point of imminent failure using the rate of change in the plurality of measurements of the at least one stress parameter is also included.
