The Triunfo Member, from Rio Bonito Formation, is a potential reservoir for hydrocarbons and water, and contains coal deposits in the northern state of Paraná. On the eastern edge of the Paraná Basin, the Triunfo Member has two depocenters in Santa Catarina and offlap to the North of Paraná; here in two adjacent areas characterized his final lapout. These areas have a number of wells core/logged with the initials MA and NF, Monte Alegre and Figueira North, which were drilled by the Companhia de Pesquisa e Recursos Minerais (CPRM), in order to research for coal in the Rio Bonito Formation. In this study, three wells in the MA area, and they were MA-4, MA-6 and MA-7 was subjected to vertical facies analysis (1D), from the description of wells and processing of data, so that later it was possible to chronocorrelate thereof, together with MA-5 well, through cycles facies (2D). This is a thesis which has never been developed in these wells mentioned above, it was possible to observe the development of part of the Member Taciba (top) and the Member Triunfo as a whole, can be determined three cycles facies to the latter, as well as their depositional environments. Finally, the chronocorrelate showed that there is a tabular architecture between the wells studied, this occurred because of subsidence uniform

The family Chironomidae is one of the most important groups within the macroinvertebrate communities, both in density and in richness, and because of its high adaptive value, has a wide distribution on the planet. These and other more specific features of each genus allow the use of this group of biomonitoring studies in the aquatic ecosystem, however, primarily, it is necessary to inventory the aquatic fauna. Thus, this study aimed to evaluate the taxonomic composition of Chironomidae associated with Eichhornia azurea in six lateral lagoons of Paranapanema River, where only five of them have very little information about the aquatic fauna associated with floating macrophytes. Furthermore, we analyzed the influence of environmental conditions on the richness and density of this community. Samples (biotic and abiotic) were held in March and August 2009 on the Ivo, Carmo, Sete Ilhas, Barbosa, Poço da Pedra and Coqueiral lagoons, which are upstream of the Jurumirim Reservoir. Samples with an area of 0.1976 m2 were collected at three banks of E. azurea of each lagoon. Then, they were washed in formaldehyde and water and fixed in 70% alcohol. The identification of morphospecies recorded 38 taxa (32 in March and 37 in August), where the Ivo lagoon is the richest (27 taxa). The density of each group varied according to each pond and is generally Asheum sp., Chironomus sp., Beardius sp., Parachironomus sp., Labrundinia sp., Tanytarsus sp., Ablabesmyia sp. and Polypedilum sp. the most representative. Limnophyes sp., Denopelopia sp., Paratanytarsus sp. and Parametriocnemus sp. were genders in lower density. The Dominance index ranged between 0.1490 (Barbosa Lagoon in March) and 0.4114 (Poço da Pedra Lagoon in March), and the Diversity Index ranged from 2.08 (Coqueiral Lagoon in March) and 3.58 (Barbosa Lagoon in August). The concentration of dissolved oxygen and pH were the environmental variables most correlated with the groups ...

The main goal in this research is a tectono-estructural characterization of the Cherne, Albacora and Namorado Fields, located at Campos Basin, in order to investigate the relationship between the geologic evolution and the rock´s physical properties of the reservoir, and how they affect the hydrocarbon accumulation in those fields. Well correlations show that the inferior turbidites have a regional lateral continuity. Basic petrophysics analysis, calculated here, shows that the three fields present porosity values that range from 15 to 20%, shale volume range from 26 to 30% and formation water saturation range from 23 to 45%, based on formation water resistivity dada from Albacora Field. Petrophysics maps feature a trend in Albacora Field that increase the porosity values to SE, and in Cherne and Namorado Field the trend increase towards N. Seismic horizons where interpreted between the first appearance of the Namorado Sandstone and the top of Quissamã Formation. This interval presents normal listric faulting, in Cherne and Namorado Field with NWSE and NE-SW direction, and sedimentation trend to NW-SE, in Albacora Field the faulting presents a NNE-SSW and N-S direction, with a sedimentation trend to NE-SW. Seismic attribute maps present amplitude anomalies close to the producing wells, and on Namorado Field, it indicates a potential hydrocarbon accumulation in the NE region. For each field is indicated laboratory tests for a better characterization of the petrophysical properties, since that they don’t form the same reservoir level, therefore, not influencing the water saturation calculation

Buscando identificar marcadores populacionais que indiquem supostos mecanismos de isolamento entre as populações, no presente trabalho foram realizadas análises filogenéticas e filogeográficas em populações de Hypostomus strigaticeps, com base em sequências de DNA mitocondrial do gene ATPase 8/6. Um total de 32 exemplares provenientes de 11 populações de quatro sub-bacias: rio Mogi-Guaçu (duas), rio Paranapanema (cinco), rio Tietê (três) e Rio do Peixe (um), tiveram DNA extraído e o gene ATPase 8/6 completamente amplificado (840 pares de base) e sequenciado. As sequências obtidas foram alinhadas com o programa Bioedit, as análises filogenéticas foram realizadas no programa MEGA 5.0 através do método de Neighbor-Joining, Máxima Parcimônia e Minimun-Evolution, com 1000 réplicas de boostrap. Para as análises filogeográficas as sequências foram analisadas no programa TCS. As análises filogenéticas mostraram que a espécie forma uma unidade monofilética composta por duas linhagens: “TG” com representantes das populações dos rios Tietê, Mogi-Guaçu e Rio do Peixe, e “PC” com representantes dos rios Paranapanema e reservatório de Chavantes. A divergência genética da linhagem “TG” é de 0,1% e da linhagem “PP” é de 0,2%, enquanto a divergência genética entre as duas linhagens é de cerca de 1%. Na análise filogeográfica observou-se a existência de seis haplótipos (A-H), sendo o haplótipo A considerado ancestral para as populações analisadas. Apenas os representantes da bacia do Tietê possuem o haplótipo ancestral. Os haplótipos A, B e F possuem a maior frequência (18,51%). Os resultados obtidos para uma população do Mogi-guaçu (Cachoeira de Emas), mostram que estes peixes são muito distantes das demais populações de H. strigaticeps, tanto no ponto de vista filogenético quanto no ponto de vista fitogeográfico...
