An accurate reservoir characterization is a crucial task for the development of quantitative geological models and reservoir simulation. In the present research work, a novel view is presented on the reservoir characterization using the advantages of thin section image analysis and intelligent classification algorithms. The proposed methodology comprises three main steps. First, four classes of...

Abstract Because of their extreme heterogeneity at multiple scales, carbonate rocks present a great challenge for studying and managing oil reservoirs. Depositional processes diagenetic alterations carbonates may have produced very complex pore structures and, consequently, variable fluid storage flow properties hydrocarbon To understand the impact mineralogy on system, we analyzed four rock sa...

the goal of this laboratory study is to investigate the effect of pore shapes on seismic wave velocities in carbonate rocks under reservoir conditions. in this research, 41 core plugs of carbonate rocks from oil fields of the southwest of iran were prepared. the compressional and shear wave velocities were measured in both dry and brine saturated samples under several pressures especially reser...

qualitative analysis of petroleum reservoir rocks is still one of the most important topics of core laboratories and directly affects hydrocarbon-in-place, fluid flow, and prediction of field performance. magnetic resonance imaging (mri) as a non-invasive, millimeter resolution technique which only images fluids in porous media fits this purpose perfectly. magnetic resonance is a radio frequenc...

This study showcases the value of drone photogrammetry in creating a meter-scale geological model complex carbonate geobodies. Although is now commonly used for modeling sedimentary facies and architecture sandstone outcrops, its use not widespread geomodels Drone can generate accurate line-drawing correlation detailed analysis along inaccessible vertical faces outcrops permits observations unr...

The shape of pores in sedimentary rocks is dependent on the geometric structure rock matrix grains. Carbonate have more complex pore types compared to clastic due effects diagenesis and depositional environment. study analyzed deposition Kais carbonate barrier lagoon environments. It categorized into inter-particle, moldic/vuggy, micro-cracks. type a directly related its stiffness shear resista...

The acoustic properties of heterozoan and photozoan carbonates are compared interpreted in the light their distinct patterns diagenetic evolution. combined role depositional processes on petroacoustic signatures both has been assessed basis a multi-disciplinary multi-scale study Oligo-Miocene limestone outcrops from Cape Range peninsula (NW Australia). This integrates detailed analysis (using s...

Abstract Unconventional geo-resources are critical due to their important contributions energy production. In this transition and sustainability era, there is an increased focus on CO 2 -enhanced oil recovery (CO -EOR) geological storage (GCS) in unconventional hydrocarbon reservoirs, the extraction of hot fluid for through enhanced geothermal systems. However, these solutions can only be achie...

Permeability is the ability of porous rock to transmit fluids and one of the most important properties of reservoir rock because oil production depends on the permeability of reservoirs. Permeability is determined using a variety of methods which are usually expensive and time consuming. Reservoir rock properties with image analysis and intelligent systems has been used to reduce time and money...
