Need support? Check EGU Meetings Support for 2016

Suzanne Hangx July 16, 2015

Are you planning to host a meeting, workshop or training school, but need some support? Check out the EGU Meetings Support scheme for 2016.

***

The EGU welcomes proposals for Topical Meetings, Training Schools and Workshops, as well as applications for EGU Sponsorship of External Meetings, for the year 2016.Successful proposals result in high profile EGU events with financial support.

Proposals for events in 2016 must be submitted by 31 July 2015 only via the online form on the EGU website.

More information about the aims, format and mechanisms of the EGU Topical Events Programme together with application guidelines can be found here.

Hello, welcome, or welcome back!

As of today ERE Matters, the blog of the Energy, Resources and Environment Division has been added to the EGU Blogs family 😀 (we thought about bringing cake, but that turned out to be a logistic distaster…)

For some of you, we are the new kid on the block, but we actually have been around already for a few months! So please, join us for your regular dose of all ERE Matters!

PS. to all our followers (we know who you are!): ERE Matters will remain active for the next year, but this will be our new location as of now, so we didn’t abandon you and we hope you come to visit us here too 🙂

ERE Division Outstanding Young Scientist Award: who would you nominate?

ERE Matters May 25, 2015

Every year the EGU rewards outstanding young or early career scientists with the Arne Richter Outstanding Young Scientist Award (OYSA), or one of the Division Outstanding Young Scientist Awards. These awards are granted for an outstanding research contribution in the Earth, planetary and space sciences, and are intended to identify the awardees as role models for the next generation of young scientists.

If you know an outstanding YS, who has made a significant contribution to Energy, Resources and the Environment, please consider nominating them for the ERE Division OYSA! 🙂

For more information on the awards and medals awarded by EGU, check here. Please be aware that all nominations must be submitted online by the 15th of June! Go to the EGU website for a checklist on what to do before you submit.

Award Ceremony at the EGU GA 2015. Will you be on stage next year?

What to see at EGU?: Words on Wednesday – The Green River Natural Analogue as A Field Laboratory To Study the Long-term Fate of CO2 in the subsurface

ERE Matters April 8, 2015

Words on Wednesday aims at promoting interesting/fun/exciting publications on topics related to Energy, Resources and the Environment. If you would like to be featured on WoW, please send us a link of the paper, or your own post, at ERE.Matters@gmail.com.

If you are interested in today’s WoW, some of the results will be presented during the EGU in session ERE5.2 Field methods and analysis of field data for CO2 geological storage, on Thursday at 15.30h in room R8. So go check it out! 🙂

Evans, J.P., Maskell, A., Nicholl, J., Pipich, V., Di, Z., Rother, G., Schaller, M., 2014. The Green River Natural Analogue as a field laboratory to study the long-term faith of CO₂ in the subsurface. Energy Procedia 63, 2821-2830.

Abstract:

Understanding the long-term response of CO₂ injected into porous reservoirs is one of the most important aspects to demonstrate safe and permanent storage. In order to provide quantitative constraints on the long-term impacts of CO₂-charged fluids on the integrity of reservoir-caprock systems we recovered some 300m of core from a scientific drill hole through a natural CO₂ reservoir, near Green River, Utah. We obtained geomechanical, mineralogical, geochemical, petrophysical and mineralogical laboratory data along the entire length of the core and from non CO₂-charged control samples. Furthermore, we performed more detailed studies through portions of low permeability layers in direct contact with CO₂-charged layers. This was done to constrain the nature and penetration depths of CO₂-promoted fluid-mineral reaction fronts. The major reactions identified include the dissolution of diagenetic dolomite cements and hematite grain coatings, and the precipitation of ankerite and pyrite and have been used as input for geochemical 1D reactive transport modelling, to constrain the magnitude and velocity of the mineral-fluid reaction front.

In addition, we compared geomechanical data from the CO₂-exposed core and related unreacted control samples to assess the mechanical stability of reservoir and seal rocks in a CO₂ storage complex following mineral dissolution and precipitation for thousands of years. The obtained mechanical parameters were coupled to mineralogy and porosity. Key aim of this work was to better quantify the effect of long-term chemical CO₂/brine/rock interactions on the mechanical strength and elastic properties of the studied formations.

Entrada formation from surface to top Carmel Fm with CO2-charged sandstone layer, overlain by a low permeability clayey siltstone showing bleaching and CO2 reaction features. A sharp contact between bleached and unbleached is observed.
