Nondestructive measurement of the oil density by using radioisotope radiation

Alexandra V. Kopteva National Mineral Resources University (University of Mines) St. Petersburg, Russian Federation
The article describes the limitations of the existing methods for qualitative and quantitative control of oil. This can be done by radioisotope measurements. The radioisotope radiation method has huge penetration strength, high sensitivity to measuring flow density, the unit parts arecompatible and easily interchangeable, and its methodology is simple.
Materials and methods
Based on Compton scattering andabsorption of the radioisotope photoelectron emission medium developed a techniquefor measuring the quality and quantity of transported oil.
It were revealed main factors affecting the results of measuring the quality and quantity of oil. The need for continuous measurement of free gas is confirmed. Measurement technique based on radioisotope radiation and main results of laboratory tests are described.
1. Radioisotope method is very effective and provides a measuring of free gas in oil flow, which has a great influence on the accuracy of measurements.
2. Radioisotope measuring system provides a measurement of the actual component composition of oil and its quantity. Thisallows developing a unified, centralized and open department to control quality of oil and transport conditions. With Radioisotope measurement system itis possible to obtain the information regarding the character and the composition of the flow transported, and, in turn, based on the results obtained, oil extraction and transportation processes may be further improved, to reduce energy, to provide low-energy transportation of hydrocarbons, to avoid the numerous accidents.
