... and modeling various physical processes on the obtained models. Our work proposes using deep learning methods for mineral and pore space segmentation instead of classical methods such as threshold image processing. Deep neural networks have long been able to show their advantages in many areas of computer...

... can efficiently improve the rock permeability through matrix cleaning by both Barium and Calcium chelation. In the first treatment test by this fluid system, around 45% of the damaged permeability was recovered. While in the second test, not only BaSO4 scale was dissolved but also the CaCO3 minerals...

... Dozens of chemical compounds, ions and minerals can react in the aforementioned chemical reactions ( Quinn et. al 2000 ). In addition to silica gel other compounds can also settle out. In ( Li et. al 1998 , Walsh et. al 1982 ) it is shown that aluminum, calcium, potassium, sodium, and iron...

... prepare structural, mineral, and mechanical digital 2D and 3D models of heterogeneous reservoir rocks at the micro-and nanoscale. Next, we perform physico-mathematical modeling of stress-strain states (SSS) and the destruction of heterogeneous materials. Based on the results of modeling, we find optimal...

... technique. It allows to test numerous "what if’ scenarios and to evaluate the effect of different factors on mineral dissolution rate at pore scale. This paves the way for improvements in acidizing job design by increasing the consistency between the models used for reactive flow modelling and pore scale...

In addition, when CO 2 was dissolved into formation water, PH value of the formation water was changed to be weakly acidic which has a certain dissolution for part of mineral composition of formation core, increasing the pore volume of reservoir. This article will launch the quantitative evaluation...
