Abstract The present study investigates the reservoir characteristics of Mount Messenger Formation Kaimiro-Ngatoro Field which was deposited in deep-water environment. A 3D seismic dataset, core data and well from were utilized to identify lithofacies, sedimentary structures, stratigraphic units, depositional environments construct geological models. Five different lithologies sandstone, sandy ...

A suite of outcrop samples from the Cauvery Basin belonging to mudrock-claystone dominated Karai Formation were analysed for nannofossil biostratigraphy in two newly measured sections at and Garudamangalam. The age Section is interpreted as early Albian Turonian, whereas Garudamangalam late Cenomanian. ‘BC’ zones Bown et al. (1998) are applicable both sections, Cenomanian Turonian ‘UC’ Burnett ...

The study area is located of ?iran District Center in the southwest Gümü?hane (NE Turkey). In this study, hydrogeochemical characteristics water resources district center were examined and metal element contents determined. area, basement rocks are represented by Eocene Kelkit formation, which composed sandstone, claystone, marl, shale tuff, unit covered unconformably Quaternary aged alluvium. ...

Abstract The European Organization for Nuclear Research (CERN) is currently undertaking a feasibility study to build the next-generation particle accelerator, named Future Circular Collider (FCC), hosted in 90–100 km subsurface infrastructure Geneva Basin, extending across western Switzerland and adjacent France. This article represents preliminary, basin-scale stratigraphic lithotype analysis ...

The end-Permian mass extinction (EPME) has been linked with the widespread development of oxygen-poor oceanic conditions. However, information on spatial extent anoxia in Panthalassa super-ocean limited. This study reports redox records from a deep-sea chert succession (the Waiheke 1 section, WHK 1, New Zealand) that was located southern mid-latitudes Panthalassa. High-resolution carbon isotope...

Introduction Recent debate has focused on the timing of events that initiated the Colorado River and first delivered sediments to fault-bounded basins in the Salton Trough. Any successful model for integration of this system must include regional linkages from the Colorado River source to the basinal depocenter in the Salton Trough. The Bouse Formation is a regionally extensive, latest Miocene ...

We experimentally determined the hydraulic properties of fractures within various rock types, focusing on a variety Variscan rocks. Flow-through experiments were performed slate, graywacke, quartzite, granite, natural fault gouge, and claystone samples containing an artificial fracture with given roughness. For slate samples, transmissivity was measured at confining pressures, pc, up to 50 MPa,...

The investigation of the mechanical behaviour swelling claystones and shales is challenging because their very low permeability high sensitivity to changes in water content. former makes it difficult carry out triaxial tests with controlled homogeneous pore pressure fields, latter results some possible effects when unsaturated extracted specimens are re-saturated prior being tested. This work p...

Palynological study of Tungu Buzum Hill was investigated with a view towards determining the age outcrop, compare its miospore content adjacent Buzu Valley carbonaceous shale, their stratigraphic relationship and paleoenvironment deposition litho-sequence. Field involved litho-description logging achieved by noting rock type, mineralogical composition, bed thickness, texture, sorting, roundness...
