In the paper the rheological properties of cr ude oil of White T iger oil-field (Vietnam) and its emulsion with sea-water, including measurement results and analytical approximation formulae for wide range of pressure, temperature and water concentration, are presented. As it is known, the crude oil of White Tiger oil-field is a high-paraffin and high-viscous oil. At the low temperature (T ~ 40°C) it behaves as non-Newtonian fluid of Bingham-Shvedov group. Therefore, beside the effective viscosity, the effective dynamic shear stress is also measured and approximated. The rheological properties of crude oil and emulsion of crude oil and water are also measured and approximated for the case when the mixture contains chemical reagent ES-3363. 1. Introduction The mixture of crude oil and water used to be met in oil exploitation practice. Using the water for displacing the oil from pores, this kind of mixture can be met in production wells, in transportation pipelines, in different equipment, processing plants and etc. [1 , 2]. In order to analyse, prognose and simulate the flow behavior it · is very important to have knowledge on the rheological properties of crude oil and its emulsion with water in wide range of pressure and temperature. 2. Measurement of rheological properties of crude oil and emulsion of crude oil and water 2 .1. Measurement procedure To investigate the. rheological properties of oil and emulsion of oil and water the following main equipment is used: Rotor Visco RV-20, acquisition RC-20, software ROT . . This equipment allows to investigate the rheological properties of medium in wide range of pressure
