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. SMART MONITORING AND DECISION MAKING FOR REGULATING ANNULUS BOTTOM HOLE PRESSURE WHILE DRILLING OIL WELLS
Abstract Real time measurements and development of sensor technology are research issues associated with robustness and safety during oil well drilling operations, making feasible the diagnosis of problems and the development of a regulatory strategy. The major objective of this paper is to use an experimental plant and also field data, collected from a basi

3. Estudo do comportamento PVT de misturas de metano e fluidos de perfuração base éster / Study of the PVT behavior of methane and ester based drilling fluids mixtures
During conventional drilling operations, it is necessary to maintain the wellbore pressure greater than the reservoir pore pressure, otherwise a kick may occur. If the well control procedure is not effective during the circulation of the formation influx out of the well, a blowout could happen, which is a dangerous event concerning safety and environmental i

4. MODELAGEM PARA O ESCOAMENTO TRANSIENTE HORIZONTAL E QUASE HORIZONTAL NA PERFURAÇÃO DE POÇOS DE PETRÓLEO / TRANSIENT MODELING OF HORIZONTAL AND NEAR HORIZONTAL FOR WELLBORE DRILLING
Dentre os custos considerados na explotação de um campo de petróleo, os de perfuração constituem uma parcela significativa do total. Dentro deste cenário, devemos estar atentos à remoção dos cascalhos gerados pela perfuração, também referido como limpeza de poços. Esta operação é, ainda hoje, um tema crítico na perfuração de poços de alta

5. PRESSURE DROP IN AXIAL FLOW THROUGH ANNULAR REGION WITH INNER CYLINDER ROTATION / QUEDA DE PRESSÃO EM ESCOAMENTO AXIAL ATRAVÉS DE REGIÃO ANULAR COM ROTAÇÃO DO CILINDRO INTERNO
The present work investigated the pressure drop generated by the flow through an annular configuration with rotation of the inner cylinder. The motivation for the work comes from the several industrial application of the configuration, such as chemical reactors, filters and in drilling operations for oil and gas wells. The experimental study was conducted in

6. Simulação numerica do comportamento mecanico do sal em poços de petroleo
Drilling incidents such as stuck pipe and collapsed casing string take place when some type of salt formations are drilled because of the high pronounced plastic behavior of the salt and the creep behavior as a function of time of this type of rock. The creep behavior becomes faster and more severe if temperature and/or pressure acting on the salt go up. The
