Based on the detailed analysis of sedimentology, diagenesis, and petrophysics, this study characterized Middle-Lower Jurassic Callovian-Oxfordian carbonate reservoirs 68 key wells in Amu Darya Basin assessed controlling factors quality target intervals. We identified 15 types sedimentary facies developed seven environments using analysis, such as evaporative platform, restricted open platform m...

The conventional approach in reservoir characterization uses an extrapolation of petrophysical properties calculated from well logs determining the entire field volume. This technique fails to acknowledge/ factor heterogeneity a reservoir, and consequently leads errors capacity quantification. research work employs deterministic seismic inversion each sand. First, sand was identified intervals ...

Abstract The thermal neutron porosity is routinely acquired in almost every well. When combined with the density, gamma ray and resistivity logs, basic petrophysical parameters of a reservoir are evaluated. design tool simple, but its interpretation complex affected by formation constituents. most challenging situation occurs when contains elements high absorption probability neutrons. existenc...

Machine learning is a form of artificial intelligence that applicable in all fields study. It incorporates many algorithms used carrying out various tasks such as classification, predictions, estimations, comparisons, approximations, optimization and selections. In estimating original oil place, which affords the explorationist foresight on total amount crude potentially reservoir. found to per...

The map of permeability distribution in the reservoirs is considered one most essential steps geologic model building due to its governing fluid flow through reservoir which makes it influential parameter on history matching than other parameters. For that, petrophysical properties that are tuned during matching. Unfortunately, prediction relationship between static petrophysics (porosity) and ...

The Zubair reservoir in the Abu-Amood field is considered a shaly sand south of Iraq. geological model created for identifying facies, distributing petrophysical properties and estimating volume hydrocarbon place. When data processing by Interactive Petrophysics (IP) software completed estimated permeability using hydraulic unit method then, three main steps are applied to build model, begins w...

The paper discusses the details of application method fluid substitution which is used for predicting elastic properties reservoir rocks and their dependence on pore porosity. This makes it possible to predict changes in response a rock saturation with different fluids. main task this was study productive zones visean deposits Yablunivske field using example single well. integration petrophysic...

Digital rock technology is becoming essential in reservoir engineering and petrophysics. Three-dimensional digital reconstruction, image resolution enhancement, segmentation, parameters prediction are all crucial steps enabling the overall analysis of rocks to overcome shortcomings limitations traditional methods. Artificial intelligence technology, which has started play a significant role man...
