The Microfacies analysis of the Cretaceous Mishrif Formation was studied in Nasiriyah oil field Governorate, southern Iraq using integrated borehole data set that included, core samples and well logs newly drilled to analyze microfacies Diagenesis Process formation, 100 thin sections for selected well. results show formation composed of: (top base) a fine-grained, limonitic fresh water limeston...

Abstract The exposed Middle Eocene (Bartonian) Qurn Formation along Qattamiya—Ain Sokhna district is measured, sampled and microscopically investigated. Besides, the vertical distribution of chemical oxides strontium (Sr) has been determined to identify their petrographic, geochemical characteristics interpret depositional environments. facies analysis (lithofacies, microfacies, biofacies) stud...

Seismic, core, drilling, logging, and thin-section data are considered to analyze the reservoir diversity in east, middle, west fan of Liushagang Formation steep-slope zone Weixinan Sag, Beibuwan Basin. Three factors primarily affect differences for systems: (1) Sedimentary mostly control scales characteristics drainage system microfacies. Massive high-quality reservoirs have shallow burial dep...

A micropaleontological study has been carried out on the samples collected from the Sarv Abad section, the oldest and only known Jurassic sedimentary rocks cropping out in the Moghan area. Studied sequence consists of carbonates bounded at both base and top by clastic deposits. Studied carbonate deposits provide an assemblage of benthic foraminifera as well as calcareous algae. The stratigraphi...

The calcareous microfossils present in the Ordovician and Silurian carbonate successions around world are limited to few studies their biological affinities environmental preferences remain indefinite. In San Juan Formation from Cerro La Chilca section, a group of was recognized and, based on size, they included calcitarch classification. Two types calcitarchs have been recognized, Type-III cal...
