The current study deals with microfacies and the depositional environment of Lower Cretaceous Sarmord Formation at selected sections in Sulaimani Erbil Governorates, northern Iraq. alternates rhythmically between yellowish grey marly limestones black marls. These lithologies are observed all studied Petrographic investigation this based on 240 thin demonstrated that carbonate constituents mainl...

The middle–late Miocene siliceous mudstones and siltstones of the Akita Aomori regions in Northern Honshu, Japan, provide an excellent geological record paleoenvironment Japan Sea. In this paper, we present results sedimentological geochemical analyses Akaishi Odoji Formations from Tsugaru Basin region Onnagawa Formation Sugisawa area region. Lithofacies descriptions, compositions (including ma...

Integrating geological concepts, such as relative positions and proportions of the different lithofacies, is of highest importance in order to render realistic geological patterns. The truncated plurigaussian simulation method provides a way of using both local and conceptual geological information to infer the distributions of the facies and then those of hydraulic parameters. The method (Le L...

Lithofacies identification and classification are critical for characterizing the hydrocarbon potential of unconventional resources. Although extensive applications machine learning models in predicting lithofacies have been applied to conventional reservoir systems, effectiveness clay-rich, lacustrine shale has yet be tackled. Here, we apply well log data automatically identify Gulong Shale So...
