The theoretical research and substantiation of specialists compliance estimation with corporate requirements on the basis of international certification and determination of its role in the system of enterprise’ staff management are carried out in the article. The algorithm of the enterprise’ effect achievement of the preliminary international certification of the personnel involved in oil and gas wells drilling is offered. The relationship between the number of persons trained and certified by International Well Control Forum in Drilling Simulation Center of the Ivano-Frankivsk National Technical University of Oil and Gas and the volume of drilling of oil and gas wells in Ukraine is analyzed. The task was accomplished by means of correlation and regression analysis. The results of the calculations allow us to make sufficiently plausible assumptions about the impact of training and certification on drilling volumes. It is established that the increase in the number of persons certified according to International Well Control Forum for one person will allow to expect the volume of drilling of oil and gas wells by 0.734 thousand metres per year.
