Improving methodological approach to measures planning for hydraulic fracturing in oil fields
Goal of the research is development of an integrated approach to the planning of hydraulic fracturing (HF) treatment taking into account geo-technical, hydrodynamic, technological and economic criteria for the selection of wells for inclusion in the programs of HF with increasing importance of economic criteria. Stages of formation of the program for HF of the oil company are selected, systematized and analyzed. It is shown that high potential effectiveness of enhanced oil recovery method in fields with hard-to-recover reserves, on the one hand, and the complexity and high cost of application, on the other, determine the need to optimize the parameters of this business process at all stages of implementation and improve its planning methods. The priority directions for improving the hydraulic fracturing planning were justified: a clear definition of the criterion for the payback period of hydraulic fracturing activities, taking into account their technological features, improving the procedure for calculating the costs of implementing this technology and improving the reasonableness of selecting candidate wells for inclusion in the hydraulic fracturing program. Feasibility of using an additional criterion in the formation of hydraulic fracturing programs – marginal minimum cost-effective wall capacity – has been shown and a method for calculating it has been developed. The use of this criterion will allow to take into account not only technological limitations, but also limits of economic efficiency of conducting hydraulic fracturing at each specific well and, at the preliminary selection of candidate wells, exclude a priori unprofitable measures.

Project finance for strategic investment projects of mining corporations
- Authors:

- N. A. Belitskaya
A strategic project realization in large companies leads to long-term competitive benefits, but is very costly, has high risks and complicated structural arrangement. Long payback period, high debt and risk burden result in the necessity to use project finance facilities. The research aims to find out conditions and justify the possibility of the use of project finance in Russian mining companies in terms of the new legal framework. Characteristics of projects requiring the use of project finance are determined. The article clarifies the principles and definition of project finance. Specific risks and realization problems of project finance in the Russian context are analyzed. A comparison between the Russian legal framework of project finance and regulation in foreign countries is made; examples and problems in the Russian project finance practice are shown. The results can be used by mining companies for justification of the optimal financial strategy for major investment projects realization.

- Authors:

There are different approaches and methods of valuation of cost of the company. Valuation of cost of the mining companies differs from a valuation of the others by some features. The most important of them is necessity of valuation mineral resources belonging to it. In work valuation of cost of the mining company is considered (for example, JSC «SOBR»). Company cost is evaluated with the positions of the two approaches: the cost and profitability, with allowance for the features inherent in mining branch. The problems arising at valuation of cost of the mining company are formulated.
