1. Ocorrência e variabilidade de composição dos fosfatos do grupo monazita em carbonatitos
Monazite structural group includes arsenates, phosphates, and silicates, with general formulae A B O4 , (A = Bi, Ca, Rare Earth Elements, Th, U and B = As5+, P5+, Si4+). Among them, the phosphate monazite is the most abundant independent Rare Earth Element mineral, occurring in several geological sites. It presents a variable composition and morphology and h

2. Importants legal aspects of geological storage of CO2 and a proposal for your regulatory model in Brasil / Aspectos importantes do armazenamento geológico de CO2 e uma proposta para o seu modelo regulatório no Brasil.
The lack of specific regulations on new technologies such as Storage of Carbon Dioxide in Geological Reservoirs (CGS) is a barrier in combating global warming and its consequences. The methodology used on this thesis was literature research and comparative analysis. Carbon Dioxide (CO2) is a greenhouse gas and its Storage in Geological Reservoirs is highligh

3. NUMERICAL MODELING OF THE CO2 INJECTION IN SALINE AQUIFERS: INVESTIGATION OF THE RELEVANT PARAMETERS FOR OPTIMIZING THE STORAGE IN CCS ¿ CARBON CAPTURE AND STORAGE PROJECTS / MODELAGEM NUMÉRICA DA INJEÇÃO DE CO2 EM AQÜÍFEROS SALINOS: INVESTIGAÇÃO DOS PARÂMETROS RELEVANTES PARA OTIMIZAR O ARMAZENAMENTO EM PROJETOS DE CCS - CARBON CAPTURE AND STORAGE
This work shows an analysis of the technique of carbon dioxide injection into saline aquifers with the purpose of discharge and storage. The final goal was to obtain the features of the aquifer, and of the injection process, to be selected in order to make the amount of stored CO2 higher and the injection time smaller. Considering such objective it was initi

4. Tecnicas geoestatisticas aplicadas na modelagem da saturação de oleo / Geostatistical tecniques applied on oil saturation modeling
Cased well logging with tools which quantify the water saturation had been done in the Study Field, located on Recôncavo Basin, considered mature and with reminiscent hydrocarbonates storage in the Sergi Formation. The geostatistical techniques of ordinary kriging and kriging with external drift had been used to the studied field for porosity and water satu

5. Caracterização hidrogeológica do aquífero cauê, quadrilátero ferrífero, MG: Subsídios para a gestão dos recursos hídricos no quadrilátero ferrífero
The Cauê aquifer encompasses the geological unit that is the host of the Iron Quadrangle bodies of iron ore (Cauê formation). It has got significant hydrogeological potential, which is used for part of the water supply for Belo Horizontes metropolitan area, and has got a fundamental importance for the maintenance of the general environmental conditions of

6. Separação e captura do dióxido de carbono em instalações marítimas de produção de petróleo. / Carbon dioxide separation and capture in offshore petroleum production facilities.
The current Brazilian market needs to increase the natural gas supply to incentive the national scientific community to the challenge of developing new technologies routes aiming increase the utilization of the produced natural gas. Such challenge is followed by a world demand from signatory countries of the Kyoto Agreement (ratified in 2005) to reduce the g

7. ContribuiÃÃo Ãs tÃcnicas de locaÃÃo de poÃos em terrenos de rochas cristalinas no semi-Ãrido brasileiro
Geological and geophysical studies were accomplished in the areas of Carnaubeira da Penha and Alagoinha in the semi-arid region of Pernambuco where Neo and Mesoproterozoic crystalline rocks occur. The study aimed at a better understanding of the variables upon which well yields are dependent in hard rock territories, in order to improve well site selection t

9. Caracterização geológico-geofísica do meio aqüífero fissural : uma contribuição aos modelos de fluxo e armazenamento de água subterrânea
Northeastern Brazil is mainly formed by crystalline terrains (around 60% in area). Moreover, this region presents a semi-arid climate so that it is periodically subject to drought seasons. Furthermore, ground water quality extracted fromwells usually presents poor quality because of their high salinity contents. Nevertheless, ground water is still a very imp

10. Curbing the U.S. carbon deficit
The U.S. emitted ≈1.58 petagrams (Pg) of fossil fuel carbon in 2001, approximately one-quarter of global CO2 production. With climate change increasingly likely, strategies to reduce carbon emissions and stabilize climate are needed, including greater energy efficiency, renewable energy sources, geoengineering, decarbonization, and geological and biologica
