Need support? Check EGU Meetings Support for 2016

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.

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

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

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.

What to see at EGU?: ERE 1.3 Fractures, mechanics and flow in tight reservoirs

Within a week the EGU General Assembly will kick off! This year the topic will be A Voyage Through Scales. For those that will attend for the first time, the scale of EGU itself may be impressive enough already. So how do you decide where to go? Here we hope to point you to a few interesting sessions, in case you get completely lost.

Today we asked Dr. Maartje Houben, one of the Young Scientists co-convening an ERE session, what we can expect from her session.

Fractures, mechanics and flow in tight reservoirs matter as well!

Unconventional oil and gas is often trapped in badly connected or even unconnected pores in the host rock (e.g. shales, tight sandstones). Hence, the presence of natural and/or induced fractures has become increasingly important in the exploitation of these natural resources. Especially in rocks with low matrix permeability’s the presence of fractures is crucial for reaching sufficient flow rates to economically produce hydrocarbons from these rocks. In addition, in order to extract heat or electricity from low-permeable geothermal reservoirs a natural or mechanical induced fracture network is also needed to improve fluid migration pathways into these reservoirs.

To discuss the interaction between fractures, mechanics and flow in all these tight reservoirs we organize the new ERE1.3 PICO session on Tuesday afternoon between 13 and 15 hrs. The session is a multi-disciplinary session and the contributors will give new insights through fast and interactive PICO presentations. A series of short 2-min madness presentations of each contribution will be followed by circa 1 hour of lively discussions in front of interactive PICO screens. The contributions will show (sub)surface fracture arrangements in tight reservoirs, either natural or modelled, and their relation to mechanical changes and changed flow behavior in these reservoirs on a multitude of scales.

Please join us on Tuesday afternoon for this exciting new session!
