Author: Wolfgang V. Preiss, Visiting Honorary Research Fellow, University of Adelaide and Geological Survey of South Australia Extract from National Rock ...Shale forms from the pressure of layers of sediment compressing bits of silt that settle into the clay on the bottom of bodies of water. The compressed clay and silt become shale over time. Shale is a sedimentary rock.A systematic analysis of the geological conditions of shale reservoir formation, the sedimentary environment, and the geological and engineering factors affecting the network fracturing effect on shale reservoirs was conducted to improve the accuracy of fracturing evaluation of shale reservoirs and improve the fracturing effect. 2. …

Existing methods heavily rely on labor-intensive manual well-to-well correlation, while automated techniques often suffer from limited efficiency and consistency due to their reliance on single well log data. To overcome these limitations, an innovative approach, termed DRAG ...Author: Wolfgang V.

Eagle Ford Shale Geology. The Eagle Ford Shale is a Cretaceous sediment that was traditionally known as a source rock in South and East Texas. The formation is the source rock for the Austin Chalk oil and gas formation. Producers also drilled through the play for many years targeting the Edwards Limestone formation along the Edwards Reef Trend.Diapir. A diapir ( / ˈdaɪ.əpɪər /; [1] [2] [3] from French diapir [djapiʁ], from Ancient Greek διαπειραίνω (diapeiraínō) 'to pierce through') is a type of igneous intrusion in which a more mobile and ductily deformable material is forced into brittle overlying rocks. Depending on the tectonic environment, diapirs can range ...3 Samples and Methods. In order to systematically analyze the geochemical characteristics and sediment source of the J 1 da shales in the northeastern Sichuan Basin, typical shale core samples were collected from the risky exploratory well Y1 in southern Yuanba area and the geological shallow well T1 in southern Puguang area based on detailed core observations. ….

Shale is a fine-grained sedimentary rock composed of a mud rich in clay- and silt-sized sediment grains. Some shale can also contain significant amounts of organic matter—the fossil remains of protozoans, microscopic animals, or plants—called kerogen. When kerogen-bearing shale is buried deeply enough and for millions of years ...

These black shales may be of particular economic interest for their relatively high uranium content (100–300 ppm) and their wide distribution from Norway to Estonia. Scandinavian Alum Shale may thus ...shale, any of a group of fine-grained, laminated sedimentary rocks consisting of silt- and clay-sized particles. Shale is the most abundant of the sedimentary rocks, accounting for roughly 70 percent of this rock type in the crust of the Earth.
