Abstract The present work aims to investigate the reservoir characterizations of Lower Cenomanian Baharyia Formation by creating isoparametic maps calculate petrophysical parameters and detect favorable parts for oil accumulations using available well logging data. is one main hydrocarbon sandstone reservoirs in northern Western Desert Egypt. About 90% field produces form Formation. This has be...

provide a test for the hypothesis of faunal change at the Triassic-Jurassic boundary recently proposed by OLSEN and SUES (1986). They are remarkable for the numerical abundance and quality of preservation of the bones, the lithological diversity of fossil-bearing deposits, and the excellent degree of stratigraphic resolution. The vertebrate remains from the McCoy Brook Formation currently repre...

Groundwater flow in sedimentary rock saprolite, and in soils derived from this material, is strongly influenced by sedimentary layering and fractures inherited from the parent bedrock. The main objectives of this study were to determine whether parent bedrock lithology and infilling of fractures and other macropores with pedogenically derived clays and Fe/Mn oxides also play major roles in cont...

-This paper based on crossplot and core data,analysis the Pu Xi oilfield ,Putao Hua oil layer ‘s conventional logging response characteristic.Based on the describe of the three cored wells, Putao Hua oil layer is mainly made up with siltstone, muddy siltstone, silty mudstone,. First normalized the well logging curves, elimination the influence of the nongeological factors to the well logging cu...

The 160 m thick Castlecliff coast section was deposited during the middle Pleistocene (c. 1.07-0.35 Ma) and comprises 10 disconformity-bound cyclothems or sequences. A typical sequence has three parts: (1) a basal suite of shoreface and inner shelf sediments with intertidal and shallow subtidal molluscan faunas, and cross-bedded, pebbly shell gravels (type A shellbeds); (2) a mid-cycle shellbed...

Nine rock types including Sandstone, Limestone, Siltstone, Dolomite and Marl collected from six different rock formations of the Salt Range area of Pakistan were tested to evaluate the correlations between the uniaxial compressive strength and the corresponding values of the point load index. Two hundred rock cores were drilled and used for the uniaxial compressive strength and point load index...

Based on geologic mapping, measured sections, and lithologic correlations, the local features of the upper and lower type areas of the Early Arikareean (30.8-20.6 million years ago) Sharps Formation are revised and correlated. The Sharps Formation above the basal Rockyford Member is divided into two members of distinct lithotypes. The upper 233 feet of massive siltstones and sandy siltstones is...

Rock pyrolysis, organic petrology, vitrinite reflectance, gas chromatography-mass spectrometry (GC-MS) analysis, and biomarker compound analysis were performed to comprehensively analyze the geochemical characteristics of Jurassic Da’anzhai Member (J 1 da) shale strata in Yuanba Puguang areas northeastern Sichuan Basin. Then matter provenance sedimentary environment further analyzed. Finally, s...

The Upper Cretaceous Lokoja Formation of southern Niger Basin in Nigeria is a dominantly sandy facies comprising of two distinctive members, the Lokoja and Patti Siltstone. The fluvial sandstone of the Lokoja Sandstone is petrologically defined as dominantly poorly sorted angular to sub-angular, fine to aly skewed, immature lithic arkose to sub-litharenite with a detrital clayey matrix of over ...
