Asphaltenes precipitation is still a challenge for the petroleum industry during crude oil production and processing. Pressure, composition, temperature variation can induce asphaltenes destabilization aggregation, leading to fouling flow blocking in pipelines wellbore pores. The present work aims investigate effect of on asphaltene using n-heptane as precipitant alkane. Three different Brazilian oils, here named BR1, BR2, BR3, were studied at temperatures 5, 25, 50 °C, two yield onset...
A wide variation in composition and thermodynamic properties is expected for different reservoir fluids, from the simplest one containing only methane light compounds to those with high compositional complexity. In this work, phase behavior of six fluids recombined was compared contrasted. From our past work (Romero Yanes, J. F.; Feitosa, F. X.; Fleming, P.; de Sant'Ana, H. B. Experimental Study Phase Behavior Methane Crude Oil Mixtures. Fuel 2019, 255, 115850, DOI:...
In this work, phase behavior was analyzed for recombined mixtures of a Brazilian pre-salt crude oil with carbon dioxide and methane. This sampled at stock tank conditions during well-test, gas were prepared molar composition ranging from 20.0 to 86.0 mol %. Their investigated 293.15 378.15 K up 100.0 MPa. Direct transition detections achieved by using full visibility PVT cell, coupled short-wave infrared camera. At wavelength, has lower absorbance, it been noted that macroscopic transitions...
The formation of emulsions is recognized to be a challenging problem during crude oil production and processing. Emulsion stability interfacial properties were investigated in this work for paraffinic modified Brazilian oils. Crude modifications made by the addition two different non-endogenous paraffins, n-hexadecane commercial pool (melting point range 53–57 °C), heavy oil, here, named P1, based on asphaltene destabilization results previously published (Romero Yanes, J. F.; Feitosa, F....
The phase behavior of petroleum fluids under reservoir conditions provides fundamental information for an adequate crude oil production scheme. Recently, complex transitions have been studied presalt oils, involving atypical liquid–liquid–vapor and liquid–liquid–asphalt transitions. In this paper, the synthetic mixtures containing carbon dioxide, methane, a Brazilian was investigated using PVT, coupled with near-infrared (NIR) transmittance high-pressure microscopy (HPM) measurements. Crude...
In this work, the phase behavior of a live presalt crude oil characterized by high CO2 content was investigated combining measurement and modeling techniques. Because complexity fluid–fluid transitions observed within system, combination indirect direct detection methods necessary to determine diagram reservoir fluid. A shortwave infrared camera used for observation occurring in an sample placed either full visibility cell or high-pressure microscopy device. addition, acoustic sensor working...
The behavior of three different Brazilian crude oils was investigated by intermediate a high-pressure titration procedure to evaluate asphaltenes stability. These oil samples were named PET-1 (16.5 ºAPI), PET-2 (26 and PET-3 (28 ºAPI) provided Petróleo Brasileiro S.A. (Petrobras). studied in PVT cell, equipped with near-infrared light scattering detector together solid detection system. titrated using n- heptane as diluent it analyzed qualitatively the evidence asphaltene precipitation....
