Abstract An essential greenhouse gas effect mitigation technology is carbon capture, utilization and storage, with dioxide (CO 2 ) injection into underground geological formations as a core of sequestration. Developing robust 3D static model the formation interest for CO storage paramount to deduce its facies changes petrophysical properties. This study investigates depleted oilfield reservoir ...

The Jurassic Lianggaoshan Formation lacustrine shale oil is the most potential exploration target of unconventional hydrocarbon resource in Southwest China. In this study, nuclear magnetic resonance (NMR), scanning electron microscopy (SEM), low-temperature N 2 adsorption (LTNA), and high pressure mercury intrusion injection capillary are intergrated to reveal pore structure its controlling fac...

Knowledge of the physical properties rock masses is fundamental for economics and safety mining projects. The determination these in samples laboratory requires time, expensive equipment qualified personnel, which considerably increases information's cost. Indirect methods were developed to obtain related masses, have been shown be a viable alternative traditional procedures. compressional mech...

Fossil remains of chondrichthyan tooth bases (roots) were found in Lower Permian beds exposed along the forest road between Dovje and Plavški Rovt. These layers are part clastic development Trogkofel Group beds. They composed an alternation dark to light-grey shales, siltstone, sandstone with rare conglomerate. Within succession, or lenses dark-grey black limestones (biosparitic, biomicritic oo...

The Aptian Crato Formation is world renowned for its well-preserved fossils in microbially-induced laminated limestones, which are regarded as one of the main Cretaceous Konservat-Lagerstätte geological record. Detailed stratigraphic investigation and mapping up to 90-m-thick at eastern border Araripe Plateau allowed recognition a regionally persistent fossil-bearing muddy interval, herein defi...

Abstract The Cretaceous sediments in southwestern Nigeria are host to one of the largest bitumen deposits world. In current paper, an integrated study on sedimentology, palynology, and applied petroleum geochemistry Maastrichtian-Paleocene Araromi Formation was used determine depositional environments hydrocarbon potentials formation eastern Dahomey Basin. Four sedimentary lithofacies were iden...

Coal mining has caused groundwater pollution and loss. Using a mined area as water storage space for storing purifying mine is low-cost environmentally friendly method. In this study, static dynamic adsorption experiments on the ions in were carried out using roof rocks from Lingxin coal mine. The sample analysis results show that main chemical composition of mainly SiO2 Al2O3. chemistry type S...

The stimulation method of the marine natural gas hydrate (NGH) reservoir through hydraulic fracturing has been proposed to resolve problem low production capacity in conventional development pressure drawdown. Nevertheless, due strong plasticity and high argillaceous siltstone content NGH reservoir, small-particle-size proppant cannot form effective support for fractures after because serious e...

ABTRACTTo extract vanadium (V) ions from the ferruginous siltstone at Abu Zeneima in Southwestern Sinai, Egypt, a synthesized chelating N-phenyl acetyl-N-naphthyl hydroxyl amine (PANHA), was used. Complete characterization carried out successfully to elucidate structure using several techniques such as FT-IR,1H-NMR, 13C-NMR, GC-MS and TGA analysis performances. Improved experimental measurement...

Abstract Movement of soil and rock masses down the slope or known as landslide is a natural activity that can pose danger to humans. Generally, be influenced by slope, materials (rock/soil), rainfall. Morphologically, study area, which located in borders Tembalang Banyumanik Districts, Semarang City, hill quite steep. It has potential experience landslides. Landslide occurences at area do not a...
