From EGU to the Real World: meet ERE Young Scientist Farhana Huq

May 18, 2015

The ERE Division loves to hear from its Young/Early Career Scientists. What is it that you do that relates to ERE? What lies beyond an ERE-oriented study or PhD? Tell us what you like about working on Energy, Resources and Environment-related research. We’d love to hear it! 🙂

Today we have Farhana Huq, who gives us some insight into how her PhD project lead to a job on the boundary between academia and industry, and what she likes about attending the EGU General Assembly.

Farhana HuqJust as an introduction, I am Farhana from Bangladesh, working as a scientist at the Institute for Energy Technology in Norway. During my PhD research, I studied the chemical changes in rock and fluid composition upon CO2 injection under simulated reservoir conditions on the laboratory scale. This project was performed under the framework of the BMBF CLEAN project, which aimed at understanding large-scale enhanced gas recovery by CO2 injection into the Altmark natural gas reservoir, Germany.

My current research activities are mostly focused on CO2 storage and monitoring techniques with oil and gas industries. I am involved in developing different monitoring techniques using solid sorbents and tracer solutions. Recently my interest shifted quite a lot to stable isotope techniques and gas geochemistry and applications of it into field scale.

EGU has always been a great platform for me to meet new people, making contacts, learning on different topics, exchanging ideas and last but not least making wonderful friends. Starting from 2010 till now, I have tried to attend EGU sessions regularly and mostly contributed in ERE division sessions by presenting posters. Every time, I returned home with very good ideas, suggestions and constructive criticism from scientists from all over the world. This year was special as I was the young scientist representative for the ERE division, as a replacement for Sian, which gave me a huge opportunity to meet young and energetic scientists from various research fields. I wish and suggest to have more meetings and activities related to collaboration, networking, workshops and training within the young scientist forum.

EGU is not just for science, but also a great way to meet new friends!

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

April 7, 2015

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!

Ice Breaker Reception

On Sunday evening the EGU General Assembly 2015 will be kicked off with the Ice Breaker Reception, at 18.30h in Foyer E. A gathering point for young scientists provides the opportunity to meet like-minded fellows, especially if it is your first time at the General Assembly or you are coming alone.

The Young Scientist Forum

The YS Forum takes place on Tuesday at 12.15 to 13.15h in room G8. Come along and meet your young scientist representatives, find out what the EGU does for young scientists and take the chance to become more involved in the Union. This forum is a great opportunity to let us know what you would like from the EGU, find out how you can get involved in the Assembly and meet other scientists in the EGU young scientist community.

Young Scientists’ Lounge

For the Young Scientists, on the Red Level of the conference centre you can find a place to take a break, grab a free coffee or soft drink and gather your thoughts away from the buzz of the Assembly. The lounge is also a great place to catch up with colleagues you haven’t seen in a while and perhaps strike up a new collaboration. On the notice boards you can find information about cultural activities on offer in Vienna. There is also the opportunity to provide feedback via suggestion boards.

Young Scientist Reception and Medallist Reception

To bring together Young Scientists and past EGU-medallists, there will be a reception with drinks and light snacks. The reception take place on Tuesday 14 April, from 19:00 to 20:30 in room Y1.

This networking reception will provide an informal setting in which scientists can establish links with outstanding early career researchers and established scientists; offering an opportunity for young scientists to find answers to specific questions, which often cannot be found in your usual textbook. It offers a great opportunity for medallists to share their experience with researchers embarking on their academic career. To attend the reception, you need to register for the event in advance via this online form. Places at the reception are limited and will be allocated on a first come, first served basis. Your place is guaranteed only once you receive a confirmation email from the EGU Communications Officer, Laura Roberts.

Sessions for YS at the General Assembly

In addition to the above networking events, there are a number of other sessions catering the YS. A short list of these sessions with a strong YS focus can be found here. Of special interest are the two career workshops, focussing on: 1) Adding value to your research experience, and 2) Job applications and interviews. Note that you must register for the workshops in advance via the links provided!
