Euroclay2015 - Energy

Asian Clay Minerals Group Research in Progress (II) (part of Euroclay2015)

steve.hillier — Thu, 11 Dec 2014 21:05:25 +0000

The Asian Clay Research Group was organized through the Nagoya and Seoul meeting in 2010 and 2012. We plan to hold the 3rd meeting in Guangzhou in 2016. Our first participation in The CMS meeting in College Station, Texas, USA (2014) was successful in terms of communicating/collaborating with other clay minerals groups. The purpose of this session, held as part of the Euroclay2015 meeting, is to bring active Asian clay scientists together and promote scientific communication and interaction with the international clay minerals community. We invite papers on, but not limited to, biotic and abiotic reactions in natural environments that impact a number of geological and environmental process, such as sediment diagenesis, colloid transport, and the mobility and the ultimate fate of organic and inorganic contaminants. Topics also include the science and technologies of industrial clays, including exploration and clay resource development, particle engineering from macro to nano, and chemical and physical modification.

The many faces of chlorite

steve.hillier — Thu, 11 Dec 2014 12:40:44 +0000

This session focuses on the many geological occurrences of chlorite: from soils to detrital sediments, to sedimentary and diagenetic systems, to hydrothermal alterations and to low- and medium-grade metamorphic rocks, chlorite is everywhere. It forms as pure grains, or as interlayers with phyllosilicates such as smectite, serpentine, and vermiculite. The aim of this session is to bring together those with an interest in chlorite in any of its many forms, to present data from a wide variety of different analytical techniques, and to promote awareness of the complexity of chlorite and above all the potential for it to provide new and useful information on many geologic processes from the surface of the earth to deep in the crust.

From microscopic pore structures to transport properties in shales (workshop follow-on session)

steve.hillier — Thu, 11 Dec 2014 12:35:28 +0000

Argillaceous media are being considered as potential host rocks for the final, safe disposal of radio-active waste, and/or as major constituent of repository systems in which wastes will be emplaced. In this context clay radwaste scientists examine various argillaceous rocks that are being considered for the underground disposal of radioactive waste, ranging from soft clays to indurated shales. In addition, the shale gas and oil community is interested in the characterization of sediments and black shales from the core- to nano-scale, focusing on clay/brine/organic interfaces and understanding how pore space evolves and affects the transport and production potential of the shale system. Through characterizing fundamental properties such as nano-/micropore connectivity, all the way up to understanding transport and mechanical fracture properties of whole-rock units, both communities are studying the geological materials with a shared set of tools, from quantum mechanics computer simulations, through advanced microscopy and diffraction methods, up to triaxial mechanical tests and large-scale transport models.

Clay minerals in the oil and gas industry

steve.hillier — Thu, 11 Dec 2014 12:28:08 +0000

Clay minerals are present in hydrocarbon source, reservoir and seal rocks and therefore characterizing their presence and properties plays an important role in understanding petroleum systems. For this session, we call, in particular, on papers that bridge the gap between research and everyday ‘Exploration and Production’ applications and issues - for both conventional and unconventional hydrocarbon accumulations – related to: rock characterization, log response calibration, drilling, diagenesis, reservoir performance, seal integrity, provenance, shale brittleness, fracture properties, organic-matter interaction, palaeo-thermometry, basin modelling, seismic response, rock physics modelling, oil sands bitumen recovery, oil-sands tailings processing, and enhanced oil recovery processes etc.

Natural zeolites – environmental, biomedical and industrial applications

steve.hillier — Thu, 11 Dec 2014 10:52:53 +0000

Natural zeolites are microporous hydrated aluminosilicate minerals having countless technological applications due to their unique physicochemical features such as cation exchange, selective adsorption, molecular sieving, catalysis, etc. As far as cation exchange is concerned, natural zeolites have been largely investigated for ammonia and heavy-metal removal, although modification of these minerals with long-chain cationic surfactants enhances their adsorption properties towards anions and low polar organic contaminants. In addition, they have also recently been considered as carriers of pharmaceutical-active ingredients. This session is designed to promote discussions on these topics but also on other interesting technological applications including water and wastewater treatment, soil remediation, treatment of radioactive waste, as well as application in the veterinarian, pharmaceutical and industrial sectors.

Clay mineral indices in palaeo-geothermal studies, hydrocarbon and geothermal prospection - third Frey-Kübler symposium

admin — Sun, 07 Dec 2014 16:44:32 +0000

During syn-depositional processes, early and late diagenesis to very-low grade metamorphism (VLGM), alteration and reaction progress with increasing temperature and pressure causes changes in clay-mineral order and clay-mineral association (paragenesis) in sedimentary and volcanic rocks. The evolution of clay minerals with depth during burial and tectonic loading is the principal focus of the symposium. The large volume of fluid involved during diagenesis leads also to drastic changes in rock porosity and to scaling in important geothermal, hydrothermal and hydrocarbon reservoirs rocks or to changes in maturity of hydrocarbons. Recently, VLGM indicators are applied in hydrothermal and geothermal renewable energy resource prospection. All these aspects require a deeper understanding of clay-mineral alteration and reaction progress to predict palaeo- or recent geothermal gradient or reservoir characteristics.
