1. Evaluación reológica de fluidos de perforación base agua con nanosílice
ABSTRACT Generally, drilling fluids may be defined as fluids with a composition that can assist the generation and removal of cuttings from the borehole to the surface. They are classified according to their base as water based mud (WBM), oil based mud (OBM) or gas. Polymers, densifiers, brines, surfactants, among others are the primary components of drillin

2. Influencia de la temperatura en ensayos de arrancamiento sobre diferentes sistemas epoxi-acero de uso en conectores de ductos flexibles
ABSTRACT In the offshore oil fields located in deep and ultra-deep waters they are used flexible pipes. In many cases inside these pipes, the hydrocarbons are transported at elevated temperatures. At the ends of the flexible pipes are installed end fittings, these are the connection with sea platforms and different subsea systems. In the assembly of end fitt

3. A new cement slurry modified with chitosan/alginate interpenetrating networks and hydroxyapatite - structural characteristics after long-term contact with hyper-saline produced water from oil well operations
ABSTRACT Oil is an important source of energy, mainly in developing countries. Important research has been conducted to find cementing procedures that guarantee safe and cost-effective oil exploration below pre-salt layers. This work aimed to make a new cement paste with cement, seawater, silica, biopolymers (chitosan and sodium alginate) and hydroxyapatite

4. ANÁLISE EXPLORATÓRIA DAS CONCENTRAÇÕES DOS METAIS NA, CA, MG, SR E FE EM EXTRATO AQUOSO DE PETRÓLEO, DETERMINADOS POR ICP OES, APÓS OTIMIZAÇÃO EMPREGANDO PLANEJAMENTO DE EXPERIMENTOS
AbstractThe purpose of this study was to evaluate the best operating conditions of ICP OES for the determination of Na, Ca, Mg, Sr and Fe in aqueous extract of crude oil obtained after hot extraction with organic solvents (ASTM D 6470-99 modified). Thus, the full factorial design and central composite design were used to optimize the best conditions for the

5. A Mixed-Integer convex formulation for production optimization of gas-lifted oil fields with routing and pressure constraints
Production optimization of gas-lifted oil fields under facility, routing, and pressure constraints has attracted the attention of researchers and practitioners for its scientific challenges and economic impact. The available methods fall into one of two categories: nonlinear or piecewise-linear approaches. The nonlinear methods optimize simulation models dir

6. Simulação do impacto da disponibilidade de sistemas no retorno econômico e produção de petróleo / Simulation of the impact of system availability on profit and petroleum production
The reservoir simulation is the basis for the forecasts of production, dimensioning of surface equipments and the planning of activities related to production. Therefore, a production strategy which generates oil and gas production curves over the operational lifetime. However, even without considering geological and economic uncertainties, in practice, this

7. Estudo de viabilidade do sistema de ancoragem de uma unidade flutuante de produção e armazenamento \"FPSO\" acoplada a um sistema de completação seca \"TLWP\". / Mooring system feasibility study of a floating production and storage unit \"FPSO\" coupled to a dry tree system \"TLWP\".
The oil and gas production in Brazilian fields are commonly found in deep water and situated far away from the coast, reaching distances of more than 100 km as, for example, in the Campos Basin or Santos Basin. Due to the heavy oil and lack of pipeline infrastructure found in these fields, not only subsea equipments that must support high pressure but also l

8. SCAE: uma abordagem baseada em agentes inteligentes para gerenciamento e controle de campos de petróleo / SCAE: an approach based on intelligent agents for management and control of oil fields / SCAE: uma abordagem baseada em agentes inteligentes para gerenciamento e controle de campos de petróleo / SCAE: an approach based on intelligent agents for management and control of oil fields
Several existing systems, whether in nature, whether in companies human exhibit the characteristic of being formed by individuals or subsystems that cooperate to carry out their tasks, and thus achieve a global goal. Examples these systems range from a society of bees to an organization financial, community animal to a manufacturing system, among many others

9. Regulação, dinâmica, riscos e oportunidades das operações de exploração e produção de campos maduros com acumulação marginais: o caso Bahia.
Since the enactment of Law n 9.478/97, which relaxed the monopoly on the extraction of oil and natural gas in Brazil, many discussions have been conducted by independent companies, associations of independent producers Association of Enterprises Producing Oil and Natural Gas Fields Extracted Marginal Brazil (APPOM), Cooperative Engineering Fields Mature (REC

10. AN ANALYSIS OF THE DROP BREAKUP PROCESS IN AN OIL IN WATER EMULSION FLOWING TETWEEN PARALLEL DISKS / ANÁLISE DO PROCESSO DE QUEBRA DE GOTAS DE UMA EMULSÃO ÓLEO-ÁGUA NO ESCOAMENTO ENTRE DISCOS PARALELOS
Oil production is usually associated with the production of water, which may be found as a continuous phase or as a dispersed phase, in emulsions. Emulsions may be found in almost all the production stages: in reservoirs, production wells, production facilities, pipelines, in processing and in storage. The Electric Submersible Pump (ESP) is one of the method

11. Development of natural gas fields under uncertainties / Desenvolvimento de campos de gas natural sob incertezas
This work studied the use of a methodology that allow calculate the risks and the value of information (VOI) in natural gas fields at initial stage of development. It is necessary to know the specific characteristics of recovery from a natural gas field, recognize uncertainties, both geological and the market and also the risks involved in investment decisio

12. Análise jurídico-constitucional do fomento aos campos maduros de produção de petróleo no Brasil
The oil activities in Brazil had been started in an intensive way in the end of the 30s and in the beginning of the 40s. Many of the brazilians fields discovered in the past are nowadays in decline. They are called ―mature fields‖. These fields, because of the decline situation that characterizes them, are not interesting for the majors. The majo
