Abstract:

AbstractFluvial and aeolian sandstones of the Sergi Formation are the most important reservoirs of the Recôncavo Basin, Brazil. Optical and scanning electron microscopy, X-ray diffraction and infrared spectroscopy revealed the occurrence of dickite, a clay mineral indicative of deep burial conditions (T >100ºC), in the shallow Buracica (630–870 m) and Água Grande (1300–1530 m) oilfields. Vermicular dickite replaces K-feldspar and plagioclase grains, and fills intra- and inter-granular pores. Its vermicular habit is a product of pseudomorphic kaolinite transformation during burial.

ABSTRACT. Tomography was incorporated in Exploration Geophysics with the intention of providing high-resolution images of regions in Earth’s subsurface that are characterized as potential reservoirs. In this work, seismic traveltime tomography in the transmission mode was applied to real data from the Dom João Field, Recôncavo Basin, State of Bahia, Brazil. This basin represents a landmark of oil exploration in Brazil and has been intensively studied since the 1950’s. Today, the Recôncavo Basin is still the principal oil producer in the State of Bahia, but there is a demand for new technologie

Abstract:

The upper clastic sediments in the Recôncavo‐Tucano basin comprise a multilayer aquifer system of Jurassic age. Its groundwater is normally fresh down to depths of more than 1000 m. Locally, however, there are zones producing high salinity or sulfur geothermal waters. In other areas, the system is being exploited heavily to support a petrochemical center and related industries. Analysis of electrical logs of more than 150 wells enabled the identification of the most typical sedimentary structures and the gross geometries for the sandstone units in selected areas of the basin.

Aquatic and marsh plants are those that have the capacity to withstand a continuous or periodic submersion in water, at least of their roots. Such plants are thus able to occupy environments that are at least periodically waterlogged.

The present study was conducted in Bahia state, through collections in 20 municipalities within the Recôncavo basin between 2009 and 2015. All species were classified across six life forms.

ABSTRACT. The hydrogeophysical features of the Recôncavo aquifer system in the area of the Capivara Grande and Capivara Pequena rivers, in Camac¸ari and Dias D’Ávila counties were studied through the analysis of 64 Schlumberger vertical electrical soundings expanded to AB/2 spacing of 1.000 m. This characterization was also supported by the analysis of lithologic logs of 29 water exploration wells, 14 of which have available geophysical logs. The results were useful to outline the structural conﬁguration of the regional aquifer system in the area, from the surface up to 450 m in depth. The mul

Abstract:

This paper presents a method to map the basement relief of homogeneous sedimentary basins that does not require the knowledge of the basin density contrast. To reach this task, the proposed method relies on the invariance of the inclination of the anomalous gravity field with the density contrast caused by models constituted by two homogeneous media. This invariance occurs because the density contrast appears as a constant factor in both vertical and horizontal gravity components, therefore being canceled out when these components are divided during the evaluation of the field inclination.

Abstract:

The objective of this work was to determine the macronutrient doses that allow the highest phytomass yield and growth of basil plants. The experiment was carried out in the experimental area of the Federal University of Recôncavo da Bahia, in Cruz das Almas, BA, in a greenhouse. The treatments were obtained according to the Baconian matrix statistical arrangement, in which one of the nutrients is supplied in variable amounts, while the others are kept at a referential level. Six nutrients (nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S)) were evaluate

Abstract:

AbstractSarcosuchus hartii was a top predator that inhabited the fluvial and coastal areas of north-eastern Brazil during the Early Cretaceous. Several fossil remains were recovered during the late 19th and early 20th centuries from strata that outcrop in the Recôncavo Basin in the state of Bahia. A re-analysis of this material shows that S. hartii is a valid species. The Brazilian taxon differs from the African Sarcosuchus imperator in the unique pattern of anastomosing ornamentation observed on the enamel surface. The inclusion of S. hartii in a novel phylogenetic analysis recovered it insid
