A digital rock-based workflow was developed, that predicts elastic properties of organic...

... characterization. However, due to limited core inventory and experimental cost, these measurements are rarely acquired. Digital Rock Physics provides a platform to simulate digitized rock volumes with the physical mechanisms to understand the dominant flow regimes and simulate ultimate recovery. We present...

... Digital rock physics is an image-based computational technique used to study the physical properties of rocks. Digital rock studies originated in sandstones, which are quartz-dominated rocks with varying amounts of feldspar, calcite, and clay. However, there are significant differences...

... ABSTRACT Elastic properties of rocks control the behavior of seismic waves such as wave amplitudes and speeds. Usually, elastic properties of rocks are measured in the laboratory. Unfortunately, some laboratory measurements are invasive. Digital Rock Physics (DRP) provides an alternative...

... ABSTRACT Describing physical properties of reservoir rocks is of great interest. Lab testing can be expensive, and may not have the desired spatial sampling for long cores. Here, we describe a hand sample of a carbonate rock comprised of calcite and dolomite. We use digital rock physics...

... ABSTRACT Digital rock physics (DRP) is used to estimate physical properties of rocks by means of digital models. Conventional digital rock physics requires very high resolution images, as grains and pores need to be well resolved in order to assign each voxel the properties of an endmember...

... ABSTRACT Digital rock physics is the bridge that connects the pore-scale physical processes with macroscopic rock physical properties. Its key paradigm is to image and digitize the pore space and mineral matrix of rock and then numerically simulating the response of various physical fields...

... ABSTRACT Micro computed tomography (µCT) is an effective way to obtain rock digital models that can be used, along with digital rock physics (DRP), to calculate rock properties. However, DRP has yielded mixed success that are in part due to limitations and uncertainty introduced...

... ABSTRACT Digital rock physics (DRP) aims at estimating rock physical properties from computed-tomography (CT) imagery. DRP could improve our knowledge of subsurface properties without increasing laboratory testing that is time consuming, expensive and might damage the rock samples. Classic DRP...

... Summary La Luna Formation in northern South America is one of the most prolific hydrocarbon source rocks in the world. Recently, La Luna Formation has also gained a significant exploration potential as an unconventional oil/gas target in Colombia. Recent developments in Digital Rock Physics...

.... Additionally, we determine the permeability of the digitized rock samples. The goals of this paper are to describe and understand how laboratory experiments couple with digital rock physics results. For a Berea Sandstone sample, we measure pressure-dependent velocities and permeability. Different approaches...

... Summary The 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. DRP complements lab measurements and, at the same time, enormously enhances the geoscientist’s capabilities because...
