Contribution of the UNU/GTP to Geothermal Development in Central American Countries-1978-2008 Contribution of the UNU/GTP to geothermal development in Central American countries-1978-2008 By Luz Barrios [email protected] El Salvador 30th Anniversary Workshop August 26-27, 2008 Benefits to the CA and Mexico Area- UNU/GTP Fellows CA Countries, energy grows between 3-5% annual one. Free Trade Agreement: Will imply an increment of over 100-200 MW in the installed capacity which now is being replaced by power stations based in oil, coal or gas. CA countries need to look urgently for renewable sources: Geothermal and depend less in a source with volatile energy prices that brings Economic, Political and Social problems as well. For an exploration work in geothermal areas in CA countries the number of specialists required varies from 6 to 8. UNU/GTP Goal UNU/GTP: to assist countries with significant geothermal potential to build up or strengthen groups of technical specialists. The training made available to CA countries and Mexico, by the UN&countries with a long tradition of geothermal energy utilization such as Iceland, has greatly contributed to the growing geothermal energy sources, not only in terms of power generation, but also in terms of sustainable development of domestic renewable resources. Recipients of the fellowship are selected based on the role of geothermal energy within the countries energy plans, the institutional capabilities for geothermal research and utilization in the respective countries and national training needs. UNU/GTP Priority is given to candidates from countries where geothermal exploration and development has been or is currently under way. Feed back from the trainees and their institutions has also contributed to modifications and improvements to the training courses.

El Salvador and Costa Rica have the highest retention with 22 and 12 active Fellows. Honduras which has not developed its geothermal resources during the last 28 years, has the smallest number of Fellows with none currently working in the geothermal industry. Two years ago, Honduras submitted 3 concession areas to private companies to explore and develop geothermal resources. It is a start point. Nicaragua started training again geothermal specialists, continuously since 2006.

An academic foundation in geology proves to be the most versatile preparation to assume a wide variety of roles. The second most prevalent academic background are the mechanical engineers, chemists and chemical engineers. Mechanical and electrical engineers work mainly as reservoir engineers, well logging and plant facilities. Physicists- in the area of geophysics. In general, engineers work in diverse areas such as: Drilling, Geothermal Utilization, Engineering of Geothermal Processes and Environmental Studies. Architects in Geothermal Utilization.

  • Supply for H Cement
    REQUEST OF PROPOSAL FOR EXPRESSION OF INTEREST – SUPPLY OF CLASS H CEMENT. Introduction LaGEO S.A. de C.V. (LAGEO), a power production company of El Salvador, is in the final stages of negotiating a loan with the World Bank (P170089 – financial identifier of the project within the World Bank) to increase the generation of electrical energy based on local geothermal resources. The scope of the project consists of the construction and commissioning of two condensing geothermal plants, one to be installed in the Chinameca geothermal field in eastern El Salvador with a generation capacity of 25 MW and the other to be placed in the San Vicente geothermal field in central El Salvador with a generation capacity of 10 MW. A vital component of these projects is drilling additional geothermal wells, which require the supply of Class H cement supply. This expression of interest request aims to understand the market for the specific requirement for the supply of Class H cement for a total of nine (9) wells in the Chinameca and San Vicente geothermal fields. Likewise, establish communication with interested companies, who will subsequently be informed about the tender process and invited to participate in it. Project Description Chinameca Geothermal Field The Chinameca geothermal field is located 130 km east of San Salvador, the capital city of El Salvador, in the department of San Miguel, within the Pacayal-Limbo volcanic complex. The towns of Chinameca and Nueva Guadalupe, both located to the north of the geothermal field. The supply of Class H cement will be used to drill six (6) geothermal wells.

  • Late Pleistocene to Holocene Temporal Succession and Magnitudes of Highly-Explosive Volcanic Eruptions in West-Central Nicaragua ⁎ S
    Journal of Volcanology and Geothermal Research 163 (2007) 55–82 www.elsevier.com/locate/jvolgeores Late Pleistocene to Holocene temporal succession and magnitudes of highly-explosive volcanic eruptions in west-central Nicaragua ⁎ S. Kutterolf a, , A. Freundt a,b, W. Pérez a, H. Wehrmann a, H.-U. Schmincke a,b a SFB 574 at Kiel university/ IFM-GEOMAR, Wischhofstr. 1-3, Gebäude 8A/213, 24148 Kiel, Germany b IFM-GEOMAR/ Research Division 4/Dynamics of the Ocean Floor, Wischhofstr. 1-3, Gebäude 8E/208, 24148 Kiel, Germany Received 2 June 2006; received in revised form 20 February 2007; accepted 23 February 2007 Available online 21 March 2007 Abstract The stratigraphic succession of widespread tephra layers in west-central Nicaragua was emplaced by highly explosive eruptions from mainly three volcanoes: the Chiltepe volcanic complex and the Masaya and Apoyo calderas. Stratigraphic correlations are based on distinct compositions of tephras. The total tephras combine to a total on-shore volume of about 37 km3 produced during the last ∼60 ka. The total erupted magma mass, including also distal volumes, of 184 Gt (DRE) distributes to 84% into 9 dacitic to rhyolitic eruptions and to 16% into 4 basaltic to basaltic–andesitic eruptions. The widely dispersed tephra sheets have up to five times the mass of their parental volcanic edifices and thus represent a significant albeit less obvious component of the arc volcanism. Eruption magnitudes (M=log10(m)−7 with m the mass in kg), range from M=4.1 to M=6.3. Most of the eruptions were dominantly plinian, with eruption columns reaching variably high into the stratosphere, but minor phreatomagmatic phases were also involved.

The maximum displacement was 2.5 m with a maximum vertical motion about 60 cm at Playa Sa Juanillo (OVSICORI Report on September 11 th , 2012). The fault displacement continued until the end of September through postseismic motions, slow earthquakes, viscoelastic response and aftershocks (> 2500 during the first 10 days following the Nicoya earthquake). The seismicity spread to most of the country (Fig.1) Figure 1: Seismicity in September 2012 and location of the main volcanoes. Yellow star: epicenter of the Nicoya seism on September 5 th , 2012 (Mw = 7.6). White arrow: direction of the displacement due to the Nicoya seism (map: Walter Jiménez Urrutia, Evelyn Núñez, y Floribeth Vega del grupo de sismología del OVSICORI-UNA). Regarding the volcanoes, the seism of Nicoya generated an important seismic activity especially in the volcanic complexes Irazú-Turrialba and Poás as well as an unusual seismic activity mainly for Miravalles, Tenorio and Platanar-Porvenir.
