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...

During the 2006–2007 austral season, the ANDRILL McMurdo Ice Shelf Project recovered a core 1285 m-long (AND-1B) from Windless Bight in the McMurdo Sound region. This core contains a range of lithologies, including both siliciclastic and volcanic diamictites, sandstones and mudstones; diatomites; and volcanic ash/tuff and one phonolitic lava fl ow. The succession has been subdivided into eight ...

This article presents Q-Facies, an open-source Python package for quantitative analysis of hydrochemical facies (HF). HF is widely used to interpret the chemical characteristics groundwater. However, it difficult analyse its spatial or temporal variability due qualitative nature and small number classes. To avoid these limitations, Q-Facies performs parametrization based on calculation five sta...

Stochastic Joint Simulation of Facies and Diagenesis: A Case Study on Early Diagenesis of the Madison Formation (Wyoming, USA) — The aim of this paper is to propose an integrated approach to reproduce both facies and diagenetic trends in a static reservoir model based on an outcrop Oil & Gas Science and Technology – Rev.

The Cretaceous deposits in Morakan, located in the northeast of Khoy, a town in western Azerbaijan province, Iran, are primarily made up of carbonate rocks. These deposits, which are of 717 meters thick, lie on the clastic facies of Jurassic and are covered with beneath the pelagic beds of the Upper Cretaceous. To investigate the facies, sedimentary environment and sequential stratigraphy of th...

The Sava depression represents the most southern part of the Pannonian basin (Fig. 1). After the Middle Eocene, a long continental phase started in the area represented by the present depression, during which tectonic movements occurred and a fault network was created along which the basin subsided by extension. The oldest proven sediments belong to the fresh-water Ottnangian deposits which are...
