Abstract Natural fractures play an essential role in the characterization and modeling of hydrocarbon reservoirs. Modeling fractured reservoirs requires understanding fracture characteristics. Fractured zones can be detected by using seismic data, petrophysical logs, well tests, drilling mud loss history core description. In this study, feed-forward neural networks (FFNN), cascade feed forward ...

the prediction of lithology is necessary in all areas of petroleum engineering. this means that todesign a project in any branch of petroleum engineering, the lithology must be well known. supportvector machines (svm’s) use an analytical approach to classification based on statistical learningtheory, the principles of structural risk minimization, and empirical risk minimization. in thisresearc...

Abstract Gamtoos Basin is an echelon sub-basin under the Outeniqua offshore of South Africa. It a complex rift-type basin with both onshore and components consists relatively simple half-grabens bounded by major fault to northeast. This study mainly focused on evaluation reservoir heterogeneity Valanginian depositional sequence. The prime objective this work generate 3D static model for better ...

Some experimental results measuring P-wave phase velocity and seismic attenuation in laboratory under dry and water-saturated conditions at ultrasonic frequencies and atmospheric pressure on sandstone samples of the Milk River Formation in the Writingon-Stone Provincial Park (WOSPP), southern Alberta, are presented and are correlated with petrophysical data obtained from these samples as clay c...

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...

Petrophysical properties of cylindrical core specimens from three boreholes the International Continental Scientific Drilling Program, DSeis project, measured at ambient pressure and room temperature conditions in various laboratories are presented compared with downhole petrophysical data (sonic density). The sixty-six rock constituting metasediments, metabasalts intrusives. Seismic velocities...
