Determination of naturally occurring radionuclides in scales produced in oil industry

Abstract

Scales produced by Oil production operations contain relatively high concentrations of natural radionuclides especially radium isotopes (Ra-226, Ra-228, Ra-224) and their daughters. These scales deposit in oil surface equipment such as separator tanks, tubular, and storage tanks. In this work, naturally occurring radionuclides and radiation exposure levels in some Syrian oil lines have been determined. Radiation measurements have shown high radiation exposure in some production sites and reached about 23 {mu}Sv/hr (production wellhead) which is higher than the normal background (0.09 - 012 {mu}Sv/hr). The highest value of the exposure around storage tanks was about o.5 {mu}Sv/hr. Moreover, the highest concentration of radionuclides in scales were found to be 47000 Bq/Kg and 55000 Bq/Kg for Ra-226 and Ra-228 respectively while in sludge samples, the Ra-226 concentration was about 24.2 Bq/Kg, a relatively very low activity. In addition, results have shown that soil contamination can occur by disposal of produced water to the surrounding environment. Furthermore, the present paper shows some of protection procedures, which should be followed by workers for radiation protection. (author). 10 refs., 4 tabs.
