Abstract
The article discusses modern methods of quantitative assessment of hydrocarbon resource structure elements in large oil and gas basins. The assessment is based on the fundamental law of hydrocarbon accumulation distribution by mass – the truncated Pareto distribution. The procedure includes the estimation of the parameters of the truncated Pareto distribution, the formation of a set of values of deposit resources and the forecast of the distribution of the quantity and their total resources by size intervals, the formation of a spatial distribution of deposits and the transformation of a set of deposits into a set of fields, the forecast of the distribution of the quantity and total resources by size intervals for deposits and fields, as well as the distribution of fields by the number of deposits in them. An analytical approach and an approach based on the simulation modeling method are described.
