Shale sediments were collected from four Cretaceous stratigraphic units across explorations well locations in South Africa’s Orange Basin and analysed to determine organic-matter characteristics, such as amount, quality, thermal maturity, their viability gas resources. The geochemical results show that the shales contain moderate organic quantities, shown by TOC averagely up 1.29%. facies consi...

On the basis of elaborating on regional geological background, this paper analyzes lithological and sedimentary characteristics explorative prospects new strata with oil gas in southern surrounding areas Dayangshu Basin. Based latest high-precision airborne gravity magnetic comprehensive survey data, combined data from explorations, physical surveys, drilling, use basin structure layering combi...

The Jiaodong Peninsula hosts the main large gold deposits and was first production area in China; multisource multiscale geoscience datasets are available. is biggest drilling mineral-exploration zone China. This study used three-dimensional (3D) modeling, geology, ore body alteration to extract synthesize mineralization information analyze exploration targeting Zhaoxian deposit northwestern Pe...

3D modeling method is divided into geospatial modeling and 3D geological modeling. 3D geological modeling technique has become a favorable tool for people to observe and analyze the geological body enriched in mineral resources. Unlike geospatial modeling, 3D geological modeling must consider various geological conditions affecting spatial shape and petrophysical distribution of geological body...
