1. Automatized Separation of Fractions from Petroleum Based on Spectrophotometric Signal Derivative Using Open-Source Hardware for the Determination of Ni and V Linked to Porphyrins
An automated method based on open-source hardware was created for the separation of porphyrins fractions from crude oil, an essential step for the quantification of V and Ni as metalloporphyrins. Preparative liquid chromatography was implemented with a reverse phase gradient from MeOH to toluene. The system allows three solvents and fractions changes by usin

2. 3-D Geological modelling: a siliciclastic reservoir case study from Campos Basin, Brazil
Abstract Reservoir static modelling plays a fundamental role in the evaluation phase of a petroleum field. Integrated modelling allows a better understanding of how the local geology and depositional systems are related through the distribution of facies and petrophysical properties within the reservoir. In this study, geological static models of the silicic

3. Evaluation of bacterial diversity recovered from petroleum samples using different physical matrices
ABSTRACT Unraveling the microbial diversity and its complexity in petroleum reservoir environments has been a challenge throughout the years. Despite the techniques developed in order to improve methodologies involving DNA extraction from crude oil, microbial enrichments using different culture conditions can be applied as a way to increase the recovery of D

4. 3D COMPOSITIONAL RESERVOIR SIMULATION IN CONJUNCTION WITH UNSTRUCTURED GRIDS
Abstract In the last decade, unstructured grids have been a very important step in the development of petroleum reservoir simulators. In fact, the so-called third generation simulators are based on Perpendicular Bisection (PEBI) unstructured grids. Nevertheless, the use of PEBI grids is not very general when full anisotropic reservoirs are modeled. Another p

5. NUMERICAL INVESTIGATION OF NON-NEWTONIAN DRILLING FLUIDS DURING THE OCCURRENCE OF A GAS KICK IN A PETROLEUM RESERVOIR
Abstract In this work, a simplified kick simulator is developed using the ANSYS® CFX software in order to better understand the phenomena called kick. This simulator is based on the modeling of a petroleum well where a gas kick occurs. Dynamic behavior of some variables like pressure, viscosity, density and volume fraction of the fluid is analyzed in the fi

6. SYNTHESIS AND CHARACTERIZATION O F SODIUM METHYL ESTER SULFONATE FOR CHEMICALLY-ENHANCED OIL RECOVERY
Abstract Attention has been given to reduce the cost of surfactant by using castor oil as an alternative natural source of feedstock. A new surfactant, sodium methyl ester sulfonate (SMES) was synthesised using ricinoleic acid methyl ester, which is obtained from castor oil, for enhanced oil recovery in petroleum industries. The performance of SMES was studi

7. Classification and Identification of Petroleum Microorganisms by MALDI-TOF Mass Spectrometry
Indigenous bacteria isolated from a crude oil sample from a deep water reservoir in the Pampo Sul Oilfield (Campos Basin-RJ, Brazil) were previously classified as strains of B. pumilus. However, their enzymatic activities with fluorogenic probes and rates of petroleum biodegradation were completely different. Some of the bacteria depleted n-alkanes, whereas

8. Terpanos pentacíclicos como indicadores de heterogeneidades composicionais em reservatório de petróleo biodegradado
Reservoir geochemistry has been effectively used to evaluate compositional heterogeneity in petroleum reservoirs by employing oil fingerprinting technique to assess reservoir continuity, primarily in paraffin oil accumulations. In-reservoir biodegradation has resulted in vast deposits of heavy oils globally; therefore, the application of reservoir geochemist

9. Simulation of multiple reservoirs sharing constrained surface facilities using integrated production modelling / Simulação de múltiplos reservatórios em cenário com restrição de superfície utilizando modelagem integrada de produção
The selection of production strategies for petroleum field development is an important task. The specific case in which there are constrained surface facilities, the allocation of production and injection well rates is one more item to be optimized. When the problem involves several segregated reservoir units, each of which characterized by its own geologica

10. Influência da argila na invasão de fluidos de perfuração em reservatórios de petróleo / Clay influence on drilling fluids invasion in petroleum reservoir
A perfuração de poços de petróleo pode danificar fortemente a formação, incluindo a região de interesse: o reservatório. Perfurar sem que se danifique o reservatório caracteriza-se como um grande desafio, e por isso, tem sido estimulado o desenvolvimento de tecnologias de fluidos e otimização de processos de perfuração, incluindo, por exemplo, o

11. Desafios e oportunidades da geração eólica e termelétrica a gás natural no Sistema Elétrico Peruano. / Challenges and opportunities of the wind generation and to natural gas thermal in the Peruvian Electricity System.
Several countries around the world have increasingly sought to diversify their electrical matrix in order to reduce dependence on fossil fuels and reduce emissions of gases responsible for worsening greenhouse effect in the atmosphere. As a result, has grown the participation of some renewable energy sources that until two decades ago did not occupied a prom

12. Aplicação de redes neurais artificiais em simulação numérica do acoplamento poço-reservatório / Artificial neural networks applied to the numerical simulation of well-reservoir coupling
No presente trabalho, desenvolveu-se uma biblioteca para geração de redes neurais artificiais (NeuralLib) e aplicou-se a mesma para aproximação do acoplamento de escoamento em poços horizontais com reservatório. A biblioteca NeuralLib foi desenvolvida em linguagem C++. A arquitetura de rede gerada e utilizada foi a Multilayer Perceptron (MLP) com uma �
