摘要： 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.

摘要： Examples described herein provide a computer-implemented method for deriving textual properties of a reservoir formation. The method includes acquiring multi-frequency dielectric data (εmeas). The method further includes applying a dielectric mixing model between different fluid phases to generate an effective fluid permittivity (εfluid) by mixing the permittivity of water and hydrocarbon fluids. The method further includes applying the dielectric mixing model between the effective fluid permittivity (εfluid) and a matrix permittivity (εm). 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 (εmeas). 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.

摘要： A method for estimating, downhole, elastic properties of a subsurface material having a bedding plane includes extracting a core sample from the subsurface material into a downhole tool, the downhole tool comprising a measurement device having a first source and a first receiver opposing the first source, the first receiver configured to receive a signal from the first source, performing at least five acoustic wave velocity measurements on the core sample in situ within the downhole tool, the measurements including compressional acoustic wave velocities and shear wave acoustic velocities with certain directions of shear acoustic wave polarization using the measurement device, estimating, with a controller, elastic properties of the core sample using the at least five acoustic wave velocity measurements, and providing an output signal comprising the elastic properties to an output signal receiving device.
