The objective area is a complex fault-block reservoir, and is provided by China Petroleum Engineering Design Competition(CPEDC). Reservoir characteristics, including stratigraphic features, vertical changes and section properties (thickness, percentage sand and percentage amalgamation) are documented. Based on comprehensive analysis on structural architecture and reservoir characteristics, a th...

An ichnological and sedimentological study of the El Frontal dinosaur tracksite (Early Cretaceous, Cameros basin, Soria, Spain) highlights the pronounced intra-trackway variation found in track morphologies of four theropod trackways. Photogrammetric 3D digital models revealed various and distinct intra-trackway morphotypes, which reflect changes in footprint parameters such as the pace length,...

Analysis of variogram is a necessary step in 3D stochastic modeling, and different settings variograms can directly affect the final distribution model attribute. How to optimize setting parameters by unit facies type has become key geological modeling. This article focuses on reservoir within sedimentary background fluvial-deltas layer SII7+8 which develops multiple microfacies, such as fluvia...

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...

This study is focused on the biostratigraphy, sedimentary environments, facies distribution, and sequence stratigraphy of the Coniacian–Santonian sediments of Tange-Bulfaris section. Five assemblage zones have been recognized by distribution of the foraminifera in the study area. Assemblage zone 1(Chara Ostracods zone) is Coniacian in age and occurs in the lower part of the succession. Assembl...

This research focusses on the facies distribution, paleoenvironment and paleoecology of the foraminifera of the Guri Member in the northern Bandar Abbas Hinterland located in the Roydar area of southern Iran. The Guri Member is 570 meters thick and composed of limestone, argillaceous limestone and marl. The distribution of the foraminifera in the study area indicates the existence of three bioz...
