1. Application of polyester derived from biomass in petroleum asphalt cement
Abstract This study evaluated the effects of the incorporation of a new additive to asphalt cement oil (CAP). A polyol product was obtained through the oxypropylation reaction of sugarcane bagasse. This polyol was polymerised with pyromellitic anhydride in order to obtain a polyester (BCP) to test its suitability in terms of the material properties to be app

2. 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

3. Estudo da perda de carga e calor no poço injetor no processo De drenagem gravitacional assistida por vapor (SAGD)
The oil companies in the area in general are looking for new technologies that can increase the recovery factor of oil contained in reservoirs. These investments are mainly aimed at reducing the costs of projects which are high. Steam injection is one of these special methods of recovery in which steam is injected into the reservoir in order to reduce the vi

4. Estudo experimental da injeção de vapor pelo método SAGD na recuperação melhorada de óleo pesado / Experimental study of steam injection on SAGD process in improved heavy oil recovery
Os métodos térmicos de recuperação viabilizaram a produção de óleo pesado em campos considerados não comerciais pelos métodos convencionais de recuperação. A injeção de vapor, em particular, veio a se consagrar ao longo dos anos e é hoje uma das principais alternativas economicamente viáveis para o aumento da recuperação dos óleos pesados.

5. Recovery of hydrocarbon liquid from waste high density polyethylene by thermal pyrolysis
Thermal degradation of waste plastics in an inert atmosphere has been regarded as a productive method, because this process can convert waste plastics into hydrocarbons that can be used either as fuels or as a source of chemicals. In this work, waste high-density polyethylene (HDPE) plastic was chosen as the material for pyrolysis. A simple pyrolysis reactor

6. Analise numerica dimensional aplicada a combustão in-situ (CIS) / Numerical and dimensional analysis applied to "in-situ" combustion (ISC)
Este trabalho apresenta uma metodologia de trabalho aplicável ao desenvolvimento de projetos de CIS utilizando dados de ensaios laboratoriais, simulação numérica e análise dimensional. A CIS envolve uma variedade de fenômenos que ocorrem simultaneamente, como a transferência de massa, calor, reações químicas entre outros. A utilização dos resulta

7. Estudo experimental da combustão molhada na recuperação de oleo pesado / Experimental study of the wet combustion on heavy oil recovery
One way to improve the performance of the oil recovery method, known as dry forward in situ combustion, is to inject water either simultaneously or intermittently with the air, named as wet forward in situ combustion. The specific heat of the dry air is considerably lower than that of water, such that water may render a better transport of the heat generated

8. In-Situ combustion : insights on field project and numerical simulation at laboratory and field scale / Combustão In-Situ : considerações sobre projeto e simulações numéricas em escala de laboratório e de campo
Behavior forecast of reservoirs subjected to in-situ combustion is hard and empirical since besides geological complexities it is necessary to reproduce complex fluid models and several chemical reactions that are part of the process. The work flow for field project usually involves: 1) reservoir screening; 2) thermo-analytical experiments; 3) combustion tub

9. Estudo paramétrico da injeção de vapor em reservatórios delgados
Exploration of heavy oil reservoirs is increasing every year in worldwide, because the discovery of light oil reservoirs is becoming increasingly rare. This fact has stimulated the research with the purpose of becoming viable, technically and economically, the exploration of such oil reserves. In Brazil, in special in the Northeast region, there is a large a

10. Estudo da segregação gravitacional do processo de injeção de vapor em reservátórios heterogêneos
Due to reservoirs complexity and significantly large reserves, heavy oil recovery has become one of the major oil industry challenges. Thus, thermal methods have been widely used as a strategic method to improve heavy oil recovery. These methods improve oil displacement through viscosity reduction, enabling oil production in fields which are not considered c

11. Steam and nitrogen injection in improved heavy oil recovery / Injeção de vapor e nitrogenio na recuperação melhorada de oleo pesado
Thermal recovery methods, especially steam injection, are at the forefront of most onshore projects of heavy oil. The continuous injection and, recently, the steam assisted gravity drainage yield high recoveries. The ratio of the volume of steam injected per volume of produced oil is a decisive parameter in the success of steam flood projects. In the present

12. Influência da areia argilosa na recuperação de petróleo por injeção de vapor
Continuous steam injection is one of heavy oil thermal recovery methods used in the Brazilian Northeast because of high occurrence of heavy oil reservoir. In this process, the oil into the reservoir is heated while reduces, substantially, its viscosity and improves the production. This work analyzed how the shaly sand layers influenced in the recovery. The s
