1. Estudo do processo de combustão in-situ usando poços horizontais como produtores de óleo (Toe-to-Hell Air Injection)
O método toe-to-heel air injection (THAITM) é um processo de recuperação de petróleo avançado, que consiste na integração da combustão in-situ com os avanços tecnológicos na perfuração de poços horizontais. Este método utiliza poços horizontais como produtores de óleo, mantendo poços injetores verticais para a injeção de ar. Este processo

2. 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

3. Oil-water liquid flow rate determined from measured pressure drop and water hold-up in horizontal pipes
Stimulated by rapid progress in down-hole measuring techniques production engineers wonder whether in the near-future monitoring of oil/water production rates for horizontal wells can become possible on the basis of measured oil/water pressure losses and water hold-ups. A complicating issue is that these measured data depend on the oil and water flow pattern

4. Interferência do vestuário no desempenho, na amplitude de movimento e no conforto na ginástica laboral
Este estudo descritivo de caso objetivou analisar a interferência do vestuário no desempenho, na amplitude de movimento (ADM) e no conforto dos exercícios físicos (EF) realizados na ginástica laboral (GL) com uniforme (UNI) e vestuário para a prática de exercícios físicos (VEF). Participaram 20 trabalhadoras com 28,9±10,2 anos de uma empresa de Flo

5. 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

6. 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

8. Integração de dados para analise de desempenho de poços de petroleo / Data integration for performance analysis of petroleum wells
In this work a new parameter called the System Performance Index is proposed, which allows a more profound study of the performance of petroleum wells. An outstanding characteristic of this parameter is that it uses a large amount of field data measured periodically. This index allows the assessing of the performance and technologies used in the wells. This

9. Well control modeling : a finite difference approach / Modelagem do controle de poços por diferenças finitas
The oil field industry has been drilling in different scenarios, subjected to high pressures and high temperatures in deep wells located in deep and ultradeep waters. The well control study in these scenarios demands a kick simulator capable to do precise predictions of the pressure behavior inside the wellbore during a kick situation. Regarding this scenari

10. Caracterização da comunidade bacteriana em água subterrânea contaminada com tetracloroeteno / Characterization of the bacterial community in groundwater contaminated with tetrachloroethene
Tetrachloroethene (PCE) is one of the most important contaminants of groundwater, since it is highly toxic and potentially carcinogenic. The bacterial communities of PCE contaminated groundwater and the diversity of bacteria capable of degrading this contaminant are barely known. The objective of this work is to compare the structure of bacterial communities

11. Estudo sobre injeção de agua acima da pressão de propagação de fratura / Study of water injection with fracture propagation pressure
Produced water re-injection is a valuable method of water disposal and pressure and energy support. A common water re-injection problem is the injectivity loss, which affects negatively the process and restrains optimal water injection rates. The injectivity loss can be minimized by water injection with fracture propagation pressure (IFPP), which aims to res

12. Estudo da recuperação de óleo por drenagem gravitacional assistida por injeção de vapor
Steam assisted gravity drainage process (SAGD) involves two parallel horizontal wells located in a same vertical plane, where the top well is used as steam injector and the bottom well as producer. The dominant force in this process is gravitational. This improved oil recovery method has been demonstrated to be economically viable in commercial projects of o
