This paper shows the availability of using Bayesian classification method to predict class membership probabilities in one deep tight reservoirs Western Desert, Egypt. The workflow our project that used deterministic petrophysical results three training wells train data and extract classifiers. classified were modeled Gaussian distribution for each lithofacies. acquired from a Jurassic gas rese...

The lacustrine fine-grained sedimentary rocks in the upper interval of fourth member Eocene Shahejie Formation (Es4s) Dongying Depression are important shale oil exploration targets Bohai Bay Basin. They widely distributed and rich organic matter. In this study, samples were observed under optical microscope FESEM, combined with geochemical test physical property analysis to study characteristi...

Natural fracture growth plays an important role in shale-oil enrichment. Systematically investigating features and their controlling factors reservoirs is essential for accurately predicting distribution. The of distribution the continental shale Qingshankou Formation Songliao Basin, China, were systematically analyzed based on quantitative characterization outcrops cores. Strata-confined fract...

Lower Permian Fengcheng Formation is considered to be a high-quality alkaline lacustrine shale oil resource in the Junggar Basin, NW China. Based on core and thin section observation, X-ray diffraction, scanning electron microscope, low-pressure N 2 adsorption, high-pressure mercury intrusion porosimetry, different lithofacies, pore structures were examined. According mineral composition, shale...

Qadir Member of Nayband Formation, located in East Central Iran, has developed to a great extent. Investigation the lithofacies and sedimentary environment, resulted identification deltaic marine deposits. Based on field evidence facies features, consists two lithofacies, including carbonate siliciclastic facies. The were identified as having four sandstone Sr, Sh, Sp, St, three fine-grained FI...

This study aims to identify favorable oil–gas reservoir facies in the Chishan group of the Wubao fault zone (Gaoyou sag, Subei basin, China) using the methods of outcrops and cores observation, granularity analysis, scanning electron microscope, log data, etc. The results suggest that the Chishan group in the studied area mainly develops desert sedimentary system, and contains five kinds of fac...
