Description
Summary:	Studies of changes in the physical and chemical properties of reservoir gas and gas cap condensate of an extremely saturated reservoir oil and gas condensate system depending on the conditions of deposits (reservoir pressures and temperatures) were carried out. The research was based on the results of laboratory analyses of 29 recombined gas samples taken from wells of the Yurubcheno-Tokhom oil and gas accumulation zone (YTZ). The main pattern of changes in the properties of gas condensates of the gas caps of the UTZ was revealed as a function of reservoir pressure. There was practically no correlation between PVT-properties determined from recombined reservoir gas samples and physical and chemical properties determined from wellhead condensate samples. A correlation between reservoir pressure and potential C5+higher content in reservoir gas (PC С5+higher ), reservoir pressure and condensate recovery coefficient was revealed. Based on this dependencies, it is possible to carry out conditional estimation of the gas condensate resources of gas caps – the potential content of C5+higher and condensate recovery coefficient for new, smal oil and gas condensate fields of the Yurubcheno-Tokhom oil and gas accumulation zone.
