Situation and Perspectives of the Geothermal Sector in Spain
More LessThe Spanish Renewable Energy Association -APPA- comprises more than five hundred companies operating in the renewable energy sector. Created in 1987, it is the only national industrial association in this field that covers all the renewables: Biofuels, biomass, wind power, photovoltaic, high and low enthalpy geothermal, hydraulic, marine, and concentrated solar energy. APPA aims to help create the conditions for development of renewable sources of energy, dialoguing with public and private entities (agencies, environmental organizations, trade unions, etc.) on the various aspects involved in its activity. APPA also lobbies in Europe through to the following European Associations: AEBIOM (European Biomass Association), EBB (European Biodiesel Board), EREF (European Renewable Energies Federation), ESHA (European Small Hydropower Association), EUFORES (European Forum for Renewable Energy Sources), EU-OEA (European Ocean Energy Association) and EWEA (European Wind Energy Association).

Underground Gas Storage in the European Gas Infrastructure
By J. WalbrechtThe underground storage of compressed natural gas (CNG) is an efficient proven common technology in use since 1915. Underground gas storage (UGS) became an essential indispensable link in the gas supply chain for adjusting gas supply to meet short-term and seasonal changes in gas demand. Natural gas produced from oil and gas fields is increasingly being used to supply energy requirements. The mainly inflexible gas production from these fields does not match with the variable market demand. Natural gas is injected into subsurface storage reservoirs when market demand falls below the level of gas delivery or if there is an economic incentive for injection. Gas is withdrawn from storage facilities to supplement the steady supply if demand exceeds that supply or withdrawal is economically attractive. UGS are designed for long operational lifetime. The construction requires long lead times and is highly capital intensive.

Carbon Capture and Storage - Opportunities and Obstacles for India
Authors P. Raj, S. Kumar and R. Kumar and A. PalCarbon Capture and Storage (CCS) has become a popular catch phrase, both in scientific arena as well as on the political discussion. India, a country with a rapidly growing economy, where rise in economic growth goes hand in hand with an increase in energy demand which is currently met, as in many evolving economies, by fossil fuels. This ultimately leads to increase in GHG emissions. With the imminent threat of anthropogenic climate change in the coming decades, helping to control India's emissions will have to be a global priority. CCS has pivotal role in curbing India's emissions in the future, given its reliance on coal power and the large coal reserves. The main objective of this paper is to increase the understanding of the opportunities, issues and obstacles amongst the stakeholders in India. To achieve this objective, we analyzed economic and institutional factors which encapsulate Indian power sector, challenges associated with the implementation, uncertainties linked with potential Co2 sources and sinks in India, needs and requirements for the future potential implementation of CCS in India. We have concluded our paper with relevant recommendations for the International Climate and CCS community to make conditions conducive for CCS in India.

Seismic Coring
Authors M. Abd ElRahman and A. Abo El RosSeismic coring obtained it’s name from the fact that it reassembles the core of the earth (which is the source) and the different layers surrounding the core (receiver lines).Another reason is because it produces data in the form of a cylinder which simulates a core sample from earth. One of the main objectives of any seismic survey is to allocate faults, anticlines, dipping beds etc, by using seismic 2-D lines, the actual fault throw and dip angle of a dipping bed will be apparent values unless the seismic line is perpendicular on them. By using a circular geophone spread with different radii, this will ensure that the geophones present on every circle to record the same arrival time leading to accurate and precise determination of the fault throw and the dip angle of a dipping bed. The resulting data would therefore have an advantage over 2-D seismic lines in the accuracy of determining fault throw and dip angle of dipping beds. two types of sources: 1-Explosive sources: for fast 3-D mapping of subsurface structures especially circular structures. 2-Vibroseis: for detailed 3-D mapping of circular structures such as salt domes and folds.

Where do we Drill? Dimensional Accuracy of Conventional and Innovative Hydraulic Geojetting Drilling Technology
Authors J.R. Riechers and R.B. BrackeFor enhancing the contribution of geothermal energy a continuous research and development is required. Especially the drilling technology has a significant potential. The economic efficiency of geothermal project depends on accruing drilling costs. The borehole quality and environmental compatibility during the drillings are largely depending on the selected drilling method. Environmental impacts during the drillings are affected by the fuel consumption of the power equipment for the drilling system and the drill rig. The purity of the used working and flushing fluid, depending on the selected drilling method, are impacting the environment. In context of a research project of the ‘GZB’ in Stockholm, Sweden, the aim was to investigate whether the innovative hydraulic GeoJetting drilling technology in an alternative to a pneumatic DTH-System in the field of geothermal drilling.

THM Modelling of a 3 Year Long Hydraulic Test at the Rosemanowes EGS Site, UK
More LessEnhancing and creating the permeability of the fractures in a HDR reservoir system have been the main challenge of numerous field studies, but there is still a lot of work toward the understanding of the physical processes involved and in the relationship in between them and occurrence of induced seismicity. It is agreed that the injection of cold fluid in a reservoir located several kilometers deep induces "small" microseisms which reflect both the pressurization of the preexisting joints and the creation of new fractures. Such micro-seismic can be very detrimental to the success of a project when their magnitude is too high. To anticipate the risks associated with this phenomenon, various hypotheses have been raised, focusing on the amount of injection rate, the presence of fractures close to an unstable mechanical system, changes the chemical properties of fluids but also the effect of long-term cooling of the rock. Our main objective is here to investigate the micro-seismic events linked to the long term cooling of the rock to obtain a better understanding of when and where they can occur, so that they can either be avoided or mitigated.

Magnetotelluric Characterization of the Research Laboratory on Geological Storage of CO2 in Hontomín Burgos, Spain
Authors X. Ogaya, P. Queralt, J. Ledo and A. Marcuello and P. PiñaA Magnetotelluric characterization of the Research Laboratory on Geological Storage of CO2 in Hontomín (Burgos, Spain) is presented here. The survey was carried out in two stages: a two dimensional (2-D) acquisition took place in spring 2010 and a three dimensional (3-D) acquisition, in autumn 2010. In total, 109 broadband magnetotelluric (BBMT) soundings have been acquired in the study area. The 2-D acquisition helped to design the 3-D survey as well as provided the first geoelectric image of the study area. The preliminary 3-D resistivity model provides the geoelectric baseline model of the Research Laboratory (3x4 km2).
