Elevated arsenic concentrations are common in water recovered from aquifer storage and recovery (ASR) systems in west-central Florida that store surface water. Investigations of the Suwannee Limestone of the Upper Floridan aquifer, the storage zone for ASR systems, have shown that arsenic is highest in pyrite in zones of high moldic porosity. Geochemical modeling was employed to examine pyrite ...

To achieve an accurate and comprehensive characterization of the multiscale pore–fracture characteristics Permian coal in Jingbian Block, Ordos Basin, a combination scanning electron microscopy (SEM), X-ray computed tomography (CT), nuclear magnetic resonance (NMR) techniques was utilized. With these experiments, mineral composition, pore size distribution (PSD), porosity, connectivity pores sa...

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...

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 present study focuses on facies analysis and the reservoir characteristics of the Asmari Formation in the Aghajari oilfield (located in the Zagros fold-thrust belt, southwest Iran), and how they are linked to depositional environments and reservoir characteristics. This formation consists of about 380 m carbonates with some siliciclastic intercalations. Based on the integration of 1200 m of...

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...

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...

Due to the diversity of pore types, it is challenging characterize Middle East’s Cretaceous carbonate reservoir or accurately predict its petrophysical properties. In this paper, structure in first classified using a comprehensive method. Then, based on identified new permeability model with high prediction precision established. The dominated by 6 such as intergrain pores and moldic pores, roc...

Rock physics models are predictive tools used to estimate the velocity, or elastic properties of formations, based on strong theoretical foundations, as opposed some simple empirical correlations that have been developed for specific regional formations. While basic rock use simplified assumptions and involve less input, more complex models, such inclusion-based velocity-porosity relation funct...

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...
