Well logs are geophysical measurements of rock properties acquired continuously along a borehole. Because the physics underlying their operation, borehole logging instruments perform local spatial averages in vicinity borehole, yielding well that often affected by tool design, layer boundaries, environmental conditions and mud-filtrate invasion. Such effects ubiquitous can lead to errors petrop...

The prediction of lithology is necessary in all areas of petroleum engineering. This means that to design a project in any branch of petroleum engineering, the lithology must be well known. Support vector machines (SVM’s) use an analytical approach to classification based on statistical learning theory, the principles of structural risk minimization, and empirical risk minimization. In this res...

shear and compressional wave velocities along with other petrophysical logs, are considered as upmost important data for hydrocarbon reservoirs characterization. shear wave velocity (vs) in well logging is commonly measured by some sort of dipole logging tools, which are able to acquire shear waves as well as compressional waves such as sonic scanner, dsi (dipole shear sonic imager) by schlumbe...

Two reservoirs domiciled in a well have been analysed this study order to obtain the quantitative reservoir properties. These properties are essential not only for development and optimization but also accurate decision-making prior exploitation production. A suite of composite logs comprising caliper log, gamma-ray (GR) density resistivity sonic transit time obtained from field onshore Niger D...

Petrophysical heterogeneity in the South Wasson Clear Fork (SWCF) reservoir and other shallow-water platform carbonates in the Permian Basin and elsewhere is composed of a large-scale stratigraphically controlled component and a small-scale poorly correlated component. The large-scale variability exists as a flow-unit scale petrophysical layering that is laterally persistent at interwell scales...

Farnsworth Field Unit (FWU), a mature oilfield currently undergoing CO2-enhanced oil recovery (EOR) in the northeastern Texas panhandle, is study area for an extensive project undertaken by Southwest Regional Partnership on Carbon Sequestration (SWP). SWP characterizing field and monitoring modeling injection fluid flow processes with intent of verifying storage CO2 timeframe 100–1000 years. Co...

Abstract Carbonate reservoirs in Iran are the most important and main sources of oil gas production. Hydrocarbon flow rates from carbonate heavily rely on development natural fractures. This study focuses role fractures reservoir quality considering Sarvak (southwest Iran) as second Iran. To identify small-scale around borehole walls, cores description image logs were utilized. Due to high cost...

Purpose. The research is aimed at evaluating the petrophysical characteristics of Late Cretaceous Matulla Formation in central part Gulf Suez order to detect its hydrocarbon reservoir potential. Methods. Well logs from five wells (Muzhil-1, -2, -4, -7, -8) were used evaluate reservoirs based on a computerized approach. Petrophysical parameters and fluid types calculated, verified using core dat...
