Abstract

The understanding of the physical properties of reservoir fluids such as viscous and interfacial forces is serious in many oil and gas, petrochemical and other connected industries. In oil and gas industry, the production, transference and processing of hydrocarbon fluids involve dealing with the multiphase system. Viscosity and Interfacial Tension (IFT) are between the fluids properties that affect fluid performance. These properties have important effects on fluid flow physiognomies and thus their importance in oil and gas production and processing features from the reservoir to other surface services. Hence correct resolve of these fluid properties theatres a vital role in forecasting multiphase flow and dealing related problems faced by the industry such as hydrates, scale and corrosion. Surfactants are other along the line, to prevent hydrate formation, by miserable the formation temperature and transport it as hydrate slurry when formed to avoid pipe blockages. While important research has been showed in reservoir conditions, but pipeline system, the presence of salt and polymer surfactants which tend to alter the IFT behavior has not been well studied. One of enhanced oil recovery methods to increase oil production is nanoparticles with polymer flooding. Combinations are considered as effective chemical agents used in lab in university of Salford. It is used to reduce the Interfacial Tension (IFT) Therefore, the aim of this work is to investigate and measure the IFT based on the air injection and conditions of combination silica nanoparticles and polymer GA at the oilfield. These parameters such as temperature, pressure, salinity as well as the attention of combination silica nanoparticles and GA polymer are used to investigate the effects on IFT reduction. From the results, it is reported that pressure from 1200 psi and temperature diverse from 30°C, 35°C, 40°C, 45°C and 50°C can decrease IFT insignificantly. Though, (combination silica nanoparticles and GA) and salinity absorption are the main parameters that effect on the IFT reduction. It can critically reduction IFT up to for combination silica nanoparticles and GA concentration and up to for salinity. Finally, the results can be practical to use in the real field for enhanced oil recovery in oilfield.
