Essay on the Future of rock physics: computational methods vs. Lab testing

In this paper, there is a complete discussion on the physical measurement of the property of rock. The author has explained the properties of rocks that are present on the core plugs. Then after this, there is deep information on the primer on permeability for the property of rock. In this report, there is a complete demonstration of the paradigm of virtual rock. This has been done through the use of state of the art imaging process and other techniques. Through this huge analysis, data is obtained in real-time so it will be quite possible to simulate different changes in a proper way. 

 In that part, the author has explained it through the help of Darcy’s equation. This equation is linear that is present between the two samples like

Q=-k A∆P/(μ L)

In this equation, Q is the main volume flux, and A is the area of the sample. 

In the above equation, there is one problem, and that is related to estimating the value of k, and it is done through the help of the Kozeny-Carman equation

k=1/2  ∅^2/(S^2 τ^2 )=d^2/72×∅^3/((1-∅)^2 τ)

In the given equation ∅ ,is theb porosity open and this equation can be used for defining the main properties of rock. In that paper, different properties of rocks are explained in a proper way. For explaining these properties in a practical way, the author had used a different kind of virtual experiments. It will help to stimulate the natural processes in a perfect way. 

In the first step of the experiment, there is a need to make an image of the rock, and it can be implemented through the help of the CT scanner. Then after this, in the next step, there is a need to apply a quantitative virtual laboratory. This has been implemented through the help of Navier-Stokes equations. The author has plotted different graphs for obtaining the permeability of the rocks. The author has also described all Tomographic slices of the 3D images in detail. 

Then after this, there is a need for quantitative virtuality when there is any mismatch in the properties of the rock. Moreover, the multiphase flow for the rocks is also tested in a proper way. But the main problem is that these experiments are providing a unique possibility. 

There is also a complete check on the factor and resistivity factor of the rocks. In the next part of the report, there is a comprehensive analysis of the elastic and inelastic properties of the rock. This can be explained through the help of virtual experimentation. 

There are also some challenges that are discussed by the author that is related to the properties of rock during the experimental setup. The major challenge that is mentioned by the author is related to the CT scan of the rock. For that case, the rock is moved through the help of geological time by applying a different kind of mathematical equations. 

The author has also demonstrated some changes that are required for the application of the paradigm of the rock. Through this, it will be quite easy to manipulate the new technologies in analyzing the main properties of the rock that is present in the sand (Dvorkin, Armbruster and Baldwin).
