The Leading Edge, 2014
A quantitative framework for relative rock physics includes a definition of relative elastic property that is rooted in inverse theory and that can be used practically to compute the properties. The framework also includes a set of rules that quantify how operations on absolute properties affect their relative counterparts.

Rock Property Determination Using Digital Rock Physics
Geophysics of the 21st Century - The Leap into the Future, 2003The Digital Rock Physics (DRP) technology is based on a rigorous numerical simulation of physical experiments in a realistic pore space, at the pore-scale level. The output is usually a macroscopic property conventionally measured in the lab. For example, a single-phase viscous fluid flow simulation through a digitized pore space provides absolute ...

Annual Review of Earth and Planetary Sciences, 1991
The concept of fractals, introduced by Mandelbrot ( 1 982), has proven to be a highly useful way to describe the statistics of naturally occurring geometries. Fluid flow, whether it be the rise and fall of rivers (Bridge & Jarvis 1 982), turbulence in air or water (Nelkin 1989), or precipitation (Mandelbrot & Wallis 1 968), is found to follow self ...

Constrained rock physics modelling
SEG Technical Program Expanded Abstracts 2008, 2008Seismic reflections are physically explained by contrasts in elastic properties in the subsurface, and rock physics is the science that links the seismic properties to geologic properties. Rock physics models attempt to quantify rock properties with physical parameters like clay content, saturation, and porosity, and use this to predict elastic rock ...

SEG Technical Program Expanded Abstracts 2001, 2001
Rock physics analysis of well log data in marl intervals shows that distinctive relations exist between the elastic propagational properties and porosity of this rock and also between Vs and Vp. In the Vs versus Vp cross plot, the marl data fall onto an experimental Vs versus Vp trend originally designed for calcite.

Predictive digital rock physics
2021Geophysical surveys are the most effective way to model the surface and subsurface. Recorded signals can only be converted to properties of interest, such as rock type or saturating fluid, if we understand the relationship between rocks and their physical properties.
