Analysis of the Gas Reserves Movement Model by Category

We consider a continuous aggregated deterministic dynamic model of the movement of gas reserves by category. According to the classification of combustible gas reserves, we characterize each type by the level of knowledge about the object, which is the carrier of information about the estimated stock of gas. We describe the movement of gas reserves by a system of differential equations and schematically depict this movement in the figure. When moving from one category to another, we take into account the degree of confirmation of reserves in the model. We pay special attention to the gas reserves multiplicity. To describe it, we introduce a time function that determines the total explored reserves of natural gas. We make a priori assumptions about its properties. We analyze six specific examples. For each sample, we determine the reserves multiplicity coefficient, the dynamics of which we analyze. We explain the behavior of the multiplicity coefficient and draw the appropriate conclusions.
