The article describes the viscometers based on the principle of measuring the ball falling time inside a calibrated tube according to the Höppler method, their disadvantages are also mentioned. Considering the existing shortcomings, a portable field viscometer has been developed at Sheshmaoil Management Company LLC, which has been certified and has successfully passed field tests. A portable viscometer enables product sampling under pressure and measuring the viscosity immediately after sampling. Measurements are carried out after removal of free gas phase from the oil-in-water mixture in order to obtain correct results.
