This paper aims to calculate the petrophysical properties in Al-Ahdab field middle of Iraq within Mauddud Formation. study was based on information available from well logs. The interactive software IP (V4.5) used porosity, hydrocarbon saturation and shale volume, divide formation into reservoir units buffer units, evaluate these each well. divided five two them were considered good reservoirs ...

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 ...

This study focuses on the geological model of sandstone formations and petrophysical characterization hydrocarbon reservoirs in Termit Basin. The specific objectives are: (1) to establish a visualizing geometry reservoir rocks (2) visualize spatial vertical distribution parameters (porosity, permeability). methodological approach integrated interpretation lithology data petrographic from logs b...

Reservoir characterization of W-field, onshore Niger Delta was carried out using petrophysical evaluation well logs. Three reservoir sand intervals (A, B, C) were identified and correlated across four wells (W1, W2, W3, W4) in W-field the gamma ray, while fluid identification each achieved resistivity log. The C interval selected utilized for interpretation penetrated at depths 11741-11945ft, 1...

Rock classification or assigning a type or class to a specific rock sample based on petrophysical characteristics is a fundamental technique to reduce the uncertainty in prediction of reservoir properties due to heterogeneity. One of the popular approaches is to classify a reservoir rock from the fundamentals of geology and the physics of flow at pore network scale. In this approach, rocks of s...

The success of shale gas in North America has attracted increased interest in “unconventional” reservoirs. Two critical factors for shale-gas reservoirs are units amenable to hydrologic fracture stimulation and sufficient natural gas content. The effectiveness of hydrologic fracture stimulation is influenced by rock geomechanical properties, which are related to rock mineralogy. The natural gas...

Porosity is important because it reflects the presence of oil reserves. Hence, number underground reserves and a direct influence on essential petrophysical parameters, such as permeability saturation, are related to connected pores. Also, selection perforation interval recommended drilling additional infill wells. For estimation two distinct methods used obtain results: first method based conv...

The present study was carried out for an oil field located in the upper Magdalena Valley basin, Colombia, which successful hydraulic fracturing a well, we denote fractured. main objective is to replicate this technique existing well same field. For work, electrical logs from twelve wells, including fractured were analyzed obtain correlation between area of interest, Monserrate Formation, and ea...
