The development of low-permeability hydrocarbon deposits is becoming increasingly important in the modern energy industry. As conventional oil and gas reserves decline, hard-to-recover reserves (HTR) are beginning to play a critical role in meeting global energy demand. Maximizing the potential of HTR is essential for ensuring a sustainable energy supply. However, developing these reserves presents significant challenges, as traditional extraction techniques used in high-permeability reservoirs are often ineffective at low-permeability deposits. These tight rock deposits characterized by low permeability and porosity require innovative approaches in drilling and extraction. Creation of cracks systems in bottom hole zones in low-permeability reservoirs can be the key to successful development and production of such fields. X-ray microcomputed tomography non-destructively produces high-resolution 3D images of rock specimens, which facilitates detailed analysis of internal properties such as connectivity, fracture aperture and orientation. This paper presents the results of a nondestructive analysis of fracturing in low-permeability reservoir rocks using a digital rock physics approach, as well as a methodology for generating high-quality 3D models of cracks systems based on X-ray CT images from a low-permeability reservoir rock.
