Geysering discharge of a geothermal wellbore at Zunil, Guatemala

Description: Within two hours after discharge began, for a production test in 1989 of well ZCQ-4, pressure variations changed from approximately sinusoidal to a cycle of sudden and complex peak discharge pressures, to 9 bar, separated by irregular pressure declines to 5 bar. Initial cycle periods of 42 minutes evolved to 150 minutes by day 20 of continuous testing, when three of four surge peaks were well separated. Chemical signatures of fluids discharged with pressure surges were distinctive. When combined with downwell pressure measurements, assignments can be made for elevations of fluid entry points. The variety of chemical signatures indicates a scarcity of interzone connectivity. These constrained discharges are suspected to derive from altered rubble zones between layered volcanic rocks.

How Do I Use Renewable Energy in My Region?

Description: NREL can asses renewable energy resource information and integrate it with data using geographic information systems (GIS) and interface the data with key analytical models. Planners and energy developers use these integrated resource assessments to make decisions about the feasibility, cost-effectiveness, and risks of developing projects in specific locations and for regional planning.

Prosperity Belief and Liberal Individualism: A Study of Economic and Social Attitudes in Guatemala

Description: Globalization has facilitated the growth of “market-friendly” religions throughout the world, but especially in developing societies in the global South. A popular belief among these movements is prosperity belief. Prosperity belief has several characteristics which make it compatible with liberal individualism, the dominant value in a globalized society. At the same time, its compatibility with this value may be limited, extending only to economic liberalism, but not to liberal attitudes on social issues. Data from the Pew Forum on Religious and Public Life’s 2006 survey Spirit and Power: Survey of Pentecostals in Guatemala is used to conduct a quantitative analysis regarding the economic and social attitudes of prosperity belief adherents in Guatemala in order to examine the potential, as well as the limits, of this belief’s compatibility with liberal individualism. Results suggest that support for liberal individualism is bifurcated. On one hand there is some support for the positive influence of prosperity belief on economic liberalism in regards to matters of free trade, but on the other hand, prosperity belief adherents continue to maintain conservative attitudes in regards to social issues. As prosperity belief and liberal individualism continue to grow along global capitalism, these findings have implications for the future of market-friendly religions and for the societies of the global South.

Malnutrition And Food Aid Programs: A Case Study From Guatemala

Description: This report is on a case study from Guatemala on malnutrition and food aid programs. The purpose of this study is to examine the impact of food aid and/or food aid programs on the nutritional status of its recipients in two regions of Guatemala. From this investigation, empirically-based programmatic statements as to the role of food aid and its impact on human society will be presented.

Climate Change in Lowland Central America During the Late Deglacial and Early Holocene

Description: The transition from arid glacial to moist early Holocene conditions represented a profound change in northern lowland Neotropical climate. Here we report a detailed record of changes in moisture availability during the latter part of this transition ({approx}11,250 to 7,500 cal yr BP) inferred from sediment cores retrieved in Lake Peten Itza, northern Guatemala. Pollen assemblages demonstrate that a mesic forest had been largely established by {approx}11,250 cal yr BP, but sediment properties indicate that lake level was more than 35 m below modern stage. From 11,250 to 10,350 cal yr BP, during the Preboreal period, lithologic changes in sediments from deep-water cores (>50 m below modern water level) indicate several wet-dry cycles that suggest distinct changes in effective moisture. Four dry events (designated PBE1-4) occurred at 11,200, 10,900, 10,700, and 10,400 cal yr BP and correlate with similar variability observed in the Cariaco Basin titanium record and glacial meltwater pulses into the Gulf of Mexico. After 10,350 cal yr BP, multiple sediment proxies suggest a shift to a more persistently moist early Holocene climate. Comparison of results from Lake Peten Itza with other records from the circum-Caribbean demonstrates a coherent climate response during the entire span of our record. Furthermore, lowland Neotropical climate during the late deglacial and early Holocene period appears to be tightly linked to climate change in the high-latitude North Atlantic. We speculate that the observed changes in lowland Neotropical precipitation were related to the intensity of the annual cycle and associated displacements in the mean latitudinal position of the Intertropical Convergence Zone and Azores-Bermuda high-pressure system. This mechanism operated on millennial-to-submillennial timescales and may have responded to changes in solar radiation, glacial meltwater, North Atlantic sea ice, and the Atlantic meridional overturning circulation (MOC).

Socioeconomic Status and Prosperity Belief in Guatemala

Description: A popular belief in the exploding Pentecostal movement in the global South is the idea that if an individual has enough faith, God will bless them with financial prosperity. Although historically Pentecostalism has been identified as a religion of the poor, this study examines recent arguments that the current Pentecostal movement in Guatemala is a religion of the socially mobile middle and elite classes. Data from the Pew Forum on Religious and Public Life’s 2006 survey Spirit and Power: Survey of Pentecostals in Guatemala is used to conduct a logistic regression, in order to measure the effects of socioeconomic status on adherence to prosperity belief. Results suggest that, contrary to the current literature on Guatemalan Pentecostalism, prosperity belief is not necessarily concentrated among the upwardly mobile middle and upper classes, but rather is widely diffused across social strata, and in particular, among those that have lower levels of education. These findings have implications for the study of Pentecostalism in Guatemala and in the global South in general.

Numerical modeling of the initial state and matching of well test data from the Zunil geothermal field, Guatemala

Description: A significant amount of geoscientific and reservoir engineering data have been collected from the Zunil geothermal field since 1973. The data have been used to define a conceptual model for the field which has formed the basis for the construction of a three dimensional numerical simulation model. The numerical model has successfully matched both the initial state of the reservoir, as indicated by subsurface temperature and pressure distributions within the presently drilled area, and available well test data. The well test data include short and long term discharge tests and a comprehensive pressure interference test. Calibration of the model will continue during 1991 when the results from drilling and testing of three additional deep wells are available. The model will then be used to study various long term production scenarios for the proposed 15 MW power development.
