This paper is an attempt to find the interdependence existing between petrophysical properties and ultrasonic wave velocities. Porosity and permeability, apart from other properties, are the two fundamental physical properties of rock responsible for storing and producing hydrocarbon. Understanding the elastic properties of such rocks is essential in developing a deep understanding about the rock and fluid models that describe the seismic response to realistic hydrocarbon reservoirs under different environmental conditions. Therefore, in this study, a detailed state-of-the-art review of the existing association between compressional and shear wave (also known as P wave and S wave) velocities (V p and V s) and different petrophysical properties (porosity, density, permeability, water absorption and clay content) has been summarized for carbonate and sandstone rock types of different regions. The relationships discussed are based on datasets measured in laboratory by various researchers under ambient conditions. An effort is made to propose a general trend (global trends) for porosity versus V p and bulk density versus V p , which is independent of the type of datasets. However, it is clear that trends do exist, but the prediction is difficult. The empirical relationships derived by various researchers are valid only to the particular dataset for which the relationship was derived. The influence of other factors like mineralogy, rock framework, pore geometry has not been studied by the researchers in their respective studies. Nevertheless, these relationships and correlations can be useful in hydrocarbon exploration industry where direct measurements may not be possible. Moreover, an accurate reservoir description can only be achieved by the integration of geological, petrophysical and geotechnical data.

The effective elastic thickness (T e ) is a geometric measure of the flexural rigidity of the lithosphere, which describes the resistance to bending under the application of applied, vertical loads. As such, it is likely that its magnitude has a major role in governing the tectonic evolution of both continental and oceanic plates. Of the several ways to estimate T e , one has gained popularity in the 40 years since its development because it only requires gravity and topography data, both of which are now readily available and provide excellent coverage over the Earth and even the rocky planets and moons of the solar system. This method, the 'inverse spectral method', develops measures of the relationship between observed gravity and topography data in the spatial frequency (wavenumber) domain, namely the admittance and coherence. The observed measures are subsequently inverted against the predictions of thin, elastic plate models, giving estimates of T e and other lithospheric parameters. This article provides a review of inverse spectral methodology and the studies that have used it. It is not, however, concerned with the geological or geodynamic significance or interpretation of T e , nor does it discuss and compare T e results from different methods in different provinces. Since the three main aspects of the subject are thin elastic plate flexure, spectral analysis, and inversion methods, the article broadly follows developments in these. The review also covers synthetic plate modelling, and concludes with a summary of the controversy currently surrounding inverse spectral methods, whether or not the large T e values returned in cratonic regions are artefacts of the method, or genuine observations.

“…Furthermore, to measure Vp, Vs in laboratory, researchers have used different ultrasonic techniques: through transmission and pulse-echo for different rock samples [10,24,25,40,43,46]. The Vp, Vs values in the rock samples can be measured either by using a pulse generator unit, a pair of transducers (one acting as a transmitter and the other one as a receiver) of frequencies varying generally from 54 kHz to 1 MHz, along with an oscilloscope [60,76] or by using portable ultrasonic non-destructive digital indicating tester, widely known as PUNDIT [55]. The literature reference regarding laboratory technique used by different researchers is summarised in Table [29,31,32] and ASTM [2][3][4] (Table 3).…”

Elastic wave velocities as indicators of lithology-based geomechanical behaviour of sedimentary rocks: an overview

et al. 2020

Different geomechanical properties such as elastic modulus/deformation modulus, Poisson's ratio (υ), uniaxial compressive strength, shear strength properties, tensile strength and point load index are widely used for rock mass characterisation in geological and geotechnical engineering. However, there are no such direct methods by which these properties can be obtained in the laboratory or in situ, without following time-consuming and a laborious procedure. Thus, ultrasonic technique, an indirect method, was found reliable to determine these properties in rocks. Many researchers have studied the correlation between the compressional wave velocity (Vp) and the geomechanical properties of sedimentary rocks such as sandstones and carbonates. However, these correlations have not considered the change in rock mineralogy, porosity and saturation conditions when deriving relationships. Hence, in this study, the authors attempt to understand the variability of Vp with the help of a fragmented analysis of major mineral constituents, porosity variation and saturation conditions for rock mass classification based on Vp. A review of the existing studies on the relationship between the rock properties and Vp has been used to perform this analysis. The resulting template can be a basis for interpreting more realistic lithology-based geomechanical behaviours and thus highlights the importance of an integrated study involving geological, petrophysical and engineering data. The results derived from fragmented analysis indicate that with an increase in quartz content and a subsequent decrease in feldspar content in sandstones, Young's modulus (E) and Vp increase. With an increase in porosity from 2 to 40%, there is a decrease in E and Vp values for all types of saturation scenarios (water, gas, brine and oil saturated) for sandstones and carbonates.
