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)...

Examples from the Polish clastic and carbonate reservoirs Central Anticlinorium, Carpathians Carpathian Foredeep are presented to illustrate possibilities of using well logging geothermal resources recognition characterization. Firstly, there was a short description selected logs methodology determination petrophysical parameters useful in investigations: porosity, permeability, fracturing, min...

Abstract A series of novel heuristic numerical tools were adopted to tackle the setback permeability estimation in carbonate reservoirs compared classical methods. To that end, a comprehensive data set petrophysical including core and log two wells was situated Marun Oil Field. Both wells, Well#1 Well#2 , completed Bangestan reservoir, having broad diversity facies. In light high Lorenz coeffic...

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 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...

Although shale gas plays have been in the spotlight recently, natural gas in tight sandstones is actually also an important hydrocarbon resource. In many cases, tight gas sandstone resources can be developed more easily than shale gas reservoirs as the rocks generally have higher quartz content, and are more brittle and easier to complete for production. This chapter first gives an overview of ...

In this paper, 2D seismic data and petrophysical logs of the Pabdeh Formation from four wells of the Mansuri oil field are utilized. ΔLog R method was used to generate a continuous TOC log from petrophysical data. The calculated TOC values by ΔLog R method, used for a multi-attribute seismic analysis. In this study, seismic inversion was performed based on neural networks algorithm and the resu...
