Abstract
A comprehensive study of water samples from the Medvezh’e, Yubileinoe, and Yamsoveiskoe oil-gas condensate fields was performed for the rapid identification of liquids from gas wells. The proportions of condensate, formation, and process waters in the produced mixture are assumed on the basis of their physicochemical parameters and chemical composition. Their dielectric parameters were studied at a frequency of 0.6 GHz. Dependences of the dielectric and radio emission parameters on the total salinity and concentrations of major cations have been established. Algorithms for identifying different types of well water based on their dielectric parameters are proposed.
