Combined ^(13)C–D and D–D clumping in methane: Methods and preliminary results
The stable isotopic composition of methane (e.g., δD and δ^(13)C values) is often used as a tracer for its sources and sinks. Conventional δD and δ^(13)C measurements represent the average isotope… Expand

Diversity analyses of microbial communities in petroleum samples from Brazilian oil fields
Abstract Recent studies of oil fields have shown that the microbial diversity is represented by bacteria and archaea of wide distribution, and that many of these organisms have potential to… Expand

Analysis of the composition of bacterial communities in oil reservoirs from a southern offshore Brazilian basin
The aim of this study was to characterize and compare the bacterial community structure of two distinct oil samples from a petroleum field in Brazil by using both molecular, based on the construction… Expand

Biomarkers in crude oil revealed by comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry: Depositional paleoenvironment proxies
Abstract Crude oil samples from two basins were analyzed using comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC×GC–TOFMS) to better understand the… Expand

Use of Hydrogen and Carbon Stable Isotopes Characterizing Oils from the Potiguar Basin (Onshore), Northeastern Brazil
Hydrogen and carbon isotopic abundances were measured in representative samples of marine- evaporitic, lacustrine, and mixed oils from the onshore Potiguar basin. The isotopic data, together with… Expand

The Parana Basin, Brazil: Chapter 33: Part II. Selected Analog Interior Cratonic Basins: Analog Basins
The Parana basin in South America is a large Ordovician-to-Cretaceous intracratonic basin filled by five major depositional sequences, predominantly siliciclastic in nature. Tectonism was generally… Expand

Isolation, biodegradation ability and molecular detection of hydrocarbon degrading bacteria in petroleum samples from a Brazilian offshore basin
Abstract The detection of microorganisms with potential for biodeterioration and biodegradation in petroleum fields is of great relevance, since these organisms may be related to a decrease in… Expand

Diversity of Hydrocarbon-Related Catabolic Genes in Oil Samples from Potiguar Basin (Rn, Brazil)
Biodegradation may result in physicochemical changes in crude oil and natural gas properties, being responsible for the decrease of saturated hydrocarbons and yielding heavy oil with low economic… Expand

Petroleum degradation by aerobic microbiota from the Pampo Sul Oil Field, Campos Basin, Brazil
Abstract Aerobic degradation of a crude oil (sample P1), collected from a deep water reservoir from the Pampo Sul Field (Campos Basin, RJ) at 82 °C and 2405–2588 m, by indigenous bacteria in the oil… Expand
