Abstract Bubble-point and dew-point pressures of oil and gas condensate reservoir fluids are used for planning the production profile of these reservoirs. Usually the best method for determination of these saturation pressures is by visual observation when a Constant Mass Expansion (CME) test is performed on a sample in a high pressure cell fitted with a glass window. In this test the cell pressure is reduced in steps and the pressure at which the first sign of gas bubbles is observed is recorded as bubble-point pressure for the oil samples and the first sign of liquid droplets is recorded as the dew-point pressure for the gas condensate samples. The experimental determination of saturation pressure especially for volatile oil and gas condensate require many small pressure reduction steps which make the observation method tedious, time consuming and expensive. In this study we have extended the Y-function which is often used to smooth out CME data for black oils below the bubble-point to determine saturation pressure of reservoir fluids. We started from the initial measured pressure and volume and by plotting log of the extended Y function which we call the YEXT function, with the corresponding pressure, two straight lines were obtained; one in the single phase region and the other in the two phase region. The point at which these two lines intersect is the saturation pressure. The differences between the saturation pressures determined by our proposed YEXT function method and the observation method was less than ± 4.0 % for the gas condensate, black oil and volatile oil samples studied. This extension of the Y function to determine dew-point and bubble-point pressures was not found elsewhere in the open literature. With this graphical method the determination of saturation pressures is less tedious and time consuming and expensive windowed cells are not required.

The results of laboratory, geological and geophysical research methods in Visean and Tournaisian reservoir rocks with complex type deposits of Kachalivske oil and gas condensate feild were analysed. The connection of structural and lithological characteristics with geophysical parameters was substantiated. In some cases, in the Visean and Tournaisian deposits, the multicomponent composition of the rock matrix affects the actual value of geophysical parameter, leading to erroneous conclusions about the reservoir, the nature of the saturation and depth of occurrence. As a result of the statistical processing of experimental laboratory studies and geophysical studies of wells in the Visean and Tournaisian deposits at Kachalivske oil and gas condensate feild, petrophysical models of reservoir rocks were developed allowing reliable determination of poroperm properties of such reservoir rocks. The developed models can be used both for determination the reservoir rock parameters and for quick interpretation of geophysical research results.

The method of the methanol content control in samples of return underground local-water of oil and gas condensate fields is described. The determination is based on a preliminary estimation of the chemical oxygen demand index, using an accelerated technique with potentiometric redox titration of potassium dichromate excess. On water-methanol solutions of known composition using the “added-found” method, it was proved that under the conditions of the chosen procedure, the methanol is completely oxidized; the value of the relative standard deviation of the determination results does not exceed 3 %. The interfering influence of the components of highly mineralized water samples on the integral assessment of chemical oxygen demand was studied. The accuracy of the determination of methanol in real water samples is proved by the method of standard additives.
