Worldwide interest in shale plays has rapidly increased in recently years, thanks to the combination of horizontal drilling and hydraulic fracturing. Shale formations act as both the source and the reservoir for the natural gas and usually exhibit anisotropic properties at larger scale. Geological and petropysical studies found that the right combination of thickness, TOC (total organic carbon)...

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 sand intervals of the Lower Goru Formation of the Cretaceous age, widely distributed in the Middle and Lower Indus Basin of Pakistan, are proven reservoirs. However, in the Sawan gas field of the Middle Indus Basin, these sandstone intervals are very deep and extremely heterogeneous in character, which makes it difficult to discriminate lithologies and fluid saturation. Based on petrophysic...

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...

The Kangan Formation (Early Triassic) is one of the most important gas reservoirs in the Zagros fold-thrust belt. The study area is located in the west of Hormozgan Province and on the Gavbandi highland. This field is one of the important gas production anticlines in the SW Iran. To investigate the reservoir quality of the Kangan Formation in these wells, 163 microscopic thin sections were prep...

The present study deals with the Petrophysical Evaluation of Nubia A Lower Cretaceous age in Formation, Ras Budran oil field, Gulf Suez, Egypt. petrophysical parameters results Formation is represented laterally (Iso-parametric maps, such as effective porosity, shale content, net-pay thickness and hydrocarbon saturation maps).A set well logs has been run for selected four wells. These wells nam...

Investigation of pore system properties of carbonate reservoirs has an important role in evaluating the reservoir quality and delineating high production intervals. The current study proposes a three-step approach for pore throat size characterization of these reservoirs, by integrating core data, well logs and 3D seismic volume. In this respect, first the pore throats size was calculated using...
