Essay on Digital Rock Physics 3D imaging of core material and correlations to acoustic and flow properties

   In this paper, the author has discussed some comprehensive properties of Digital rock physics in detail. This is done through the help of 3D imaging of the rock and then finds its correlations. The author has given comprehensive information and detail about the 3D X-ray microtomographic imaging of the rock. There is also some comprehensive information about the petrophysical properties of the substance. This paper is a complete reflection on further development in the field of emerging technology for the different cores of the rock. For that case, the author has described the 3D coupling of the imaging data of the rock. Then after this, there is a complete petrographic analysis of the material.

            Before explaining this, the author has demonstrated a complete background about the elastic properties of the rock and also the porous sedimentary rocks. Such properties are determined through proper analysis of the 3D imaging of the rock. But the main problem was that the systems were not accurate and fast enough to carry out the information of pores that are present on a rock. There was no comprehensive information given about the flow because it was just determined through the size and shape of the rock.

            The author has explained that this problem can be solved through the help of Micro-CT imaging. The reason is that it is capable of gain the 3D preview about the rock and its pores in an efficient way. In the past, there are many researchers that had worked on the pore network that is present in the rocks. Through this, it will become extremely easy to analyze the main properties of rock.

Later on, the author has given proper information about the acoustic properties of Classics. Its properties are predicted by the sintered granular media. The author has explained that these properties are gained through the help of the prediction of the 3D image data about the pores present in the rocks. Then after performing Sintering, it would be quite easy to analyze the packed particles that are present in the rock. Another one of the most important methods mentioned by the author is a finite element method. Through this method, it will be quite easy to analyze its elastic properties in a proper way.

Another method is mentioned by the author is related to making a prediction about the elastic properties of the reservoir core. Furthermore, the author has demonstrated some acoustic properties of the carbonates in a comprehensive way. it can be noted that due to heterogeneity of the carbonates reservoirs that are present at different scales, it will become extremely difficult for the company to elaborate the velocity porosity trends (MARK A. KNACKSTEDT).

It is one of the huge challenges to describe the placing of pores that are present in the carbonates rocks. The main reason is that the carbonate rocks contain extremely tiny pores, so it will be quite difficult to analyze and relate in a proper way. For that case, the author has combined the two important technologies.

It can be noted that it is extremely difficult to estimate the petrophysical properties of the rock through the help of digital imaging. For that case, there is the use of tomographic imaging to get perfect samples of the rocks. The author has mentioned that, through the help of this approach, it will be quite easy to understand the correlation between the pores of the rock. Moreover, it will also be possible to get a comprehensive analysis of the small pores of the carbonate rocks (MARK A. KNACKSTEDT).
