Oilfield service companies, in particular, have been developing innovative and efficient solutions to explore, map and produce these resources. Geophysical surveying, notably with electromagnetic methods, and integrated subsurface modeling in multi-disciplinary software platforms allow the characterization and quantification of the resource prior to drilling. Dedicated technologies for high pressure, high temperature drilling, including muds and bits, are used to realize highly deviated wellbores. Wellbore logging, either wireline or while drilling, provides the data to characterize the properties of the reservoir rock (porosity, permeability, presence of fractures) and to analyse well integrity. Production can be enhanced by stimulation treatments and by the installation of surface or downhole pumps. The combination of these services under a single provider may optimize the efficiency of well construction and resource characterization.","PeriodicalId":207171,"journal":{"name":"First EAGE/IGA/DGMK Joint Workshop on Deep Geothermal Energy","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133571608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the frame of the french-serbian GOSPEL program (Geothermal Serbian Pilot projects for Heat and Electricity), a state of the art of the synergies and challenges of co-production has been performed. The knowledge of co-production potential at worldwide scale remains limited, but numerous countries have started investigating this topic. On-going projects were mapped, revealing a large diversity of initiatives in regards to the geological settings, possible well configurations and thermal co-production capacities. Besides, the opportunities for hydrocarbon-geothermal co-production in Serbia were studied. Technologies suited to exploit the geothermal fluid and the recovered methane for heat or power production have been identified. Based on the available data of gas contents in geothermal fluids, areas of interest for co-production projects could be selected. Then, different scenarios were considered to assess the techno-economic potential of two sites, based on performance evaluation and a simplified economic model. The preliminary calculations showed that, in all scenarios, methane can be extracted and its combustion can be used for heat and electricity production. The geothermal fluid could also be exploited for heat or power production, depending on the geothermal resource quality and flow volume.","PeriodicalId":207171,"journal":{"name":"First EAGE/IGA/DGMK Joint Workshop on Deep Geothermal Energy","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131118578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In case of geothermal energy production there are many site-specific factors influencing corrosion processes e.g. high salinity, pH, high temperature, presence of non-condensable gases, fluid velocity, corrosion products, geometry of the power plant, acid treatment and acid cleaning procedures (Guerra & Jacobo 2012). To prolongate the lifetime and thus decrease downtime periods and economic losses, a careful material selection at acceptable costs is essential (Carter & Cramer 1992). Nogara & Zarrouk (2018b) summarized the results of 172 tested metals and alloys for the use in geothermal environment. Among low cost carbon steels, stainless steels, alloys and titanium are employed for functional parts as turbine blade or heat exchanger material respectively (e.g. Ravier et al. 2016). In geothermal power plants up to 12 types of corrosion may occur depending on the corrosiveness of the produced brine (e.g. Nogara & Zarrouk 2018a).","PeriodicalId":207171,"journal":{"name":"First EAGE/IGA/DGMK Joint Workshop on Deep Geothermal Energy","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115225739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although this process has been largely studied, it is not clear how the injected fluid influences the rupture size of the induced events. Here we re-investigate the induced earthquakes that occurred during an injection at Soultz-sousForêts, France in 1993 and studied the link between the injected fluid and the source properties of the numerous induced earthquakes. We take advantage that deep borehole accelerometers were running in the vicinity of the injection site. We estimate the moment and radius of all recorded events based on a spectral analysis and classify them into 663 repeating sequences. We show that the events globally obey the typical scaling law between radius and moment. However, at the scale of the asperity, fluctuations of the moment are important while the radii remain similar suggesting a variable stress drop or a mechanism that prevents the growth of the rupture. This is confirmed by linking the event source size to the geomechanical history of the reservoir. In areas where aseismic slip on preexisting faults has been evidenced, we observed only small rupture sizes whereas in part of the reservoir where seismicity is related to the creation of new fractures, a wider distribution and larger rupture sizes are promoted. Implications for detecting the transition between events related to pre-existing faults and the onset of fresh fractures are discussed. We also compare this behavior with those of other deep geothermal circulations in Northern Alsace, France (Soultz-sous-Forêts and Rittershoffen).","PeriodicalId":207171,"journal":{"name":"First EAGE/IGA/DGMK Joint Workshop on Deep Geothermal Energy","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131158645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
