Main factors of oil producing effectiveness are marked out and also indicators of oil resources provision are suggested. Defined probable directions of further researches, related to the declining extraction oilfields’ valuation.
The article covers the approach to the development project probabilistic estimation of building stone deposit. The approach is based on the Monte-Carlo simulation modelling of its efficiency indicators. Also the correlation and statistical analysis of simulation are conducted.
