Abstract
The paper shows that the correlations used in calculating reserves or forecasting oil and gas production volumes can be modified based on laboratory samples, which increases the accuracy of their PVT properties. This made it possible to identify “problematic” objects in which the gas content values were underestimated or the volume coefficients were overestimated, as well as to exclude from the selection program layers whose PVT properties coincided with the values determined by modified correlations.
Materials and methods
Materials: results of laboratory examination of deep samples.
Methods: calculation of PVT properties of the formation by author’s correlations, estimation of the average deviation of experimental data from calculated PVT properties of formations, optimization of correlation parameters by the Newton method based on laboratory sample data.
Keywords
PVT-properties, correlation, modified correlation, oil and gas, correlation applicability matrix
