The efficient development of tight oil exploration and development domestic and foreign has been a difficult, hot issues, using conventional reservoir reconstruction process, the yield increase is limited. Ordos Basin in the Chang 7 layers of tight oil reserves on behalf of a large scale, widely distributed, in order to reinforce to achieve fifty million tons of Changqing Oilfield stable long-term strategic objectives of the resource base and improve the tight oil well production, faced with enormous challenges. For Changqing Oilfield tight reservoir geological features, learn from foreign experience in tight oil development success, positive change in Changqing Oilfield reservoir reconstruction,approach to volume fracturing as a concept, greatly contributed to the Chang 7 represented tight reservoir of cost effective development, the effect is significant, strategic breakthrough.

Subject. The article analyzes the expected effect of a portfolio of projects in the face of risk and uncertainty, when using real options. Objectives. The purpose is to offer a more objective formula to assess the expected impact of a portfolio of projects for real investment objects under risk and uncertainty, using real options, and provide recommendations for improving the portfolio efficiency. Methods. The study draws on methods of real options and evaluation of investment projects through the real option value, the cash flow discounting method, synthesis, and mathematical modeling. Results. We systematized the main types of real options and developed a formula for calculating the expected effect of project portfolio implementation. The said formula shows that considering the additional long-term costs embedded in a portfolio of real options, which are associated with the use of these real options, and, therefore, reducing the overall risk of projects and the entire portfolio, permit to improve the objectivity of such calculations. Conclusions. When analyzing real options that have real assets as underlying instruments, it is often impossible to apply the computational formulae for financial options, as they differ significantly. The systematization of the main types of real options helps expand the range of application of management solutions. The offered formula enables to improve the efficiency of project insurance under risk and uncertainty and to use additional opportunities for effective development of the company.

Subject. This article explores the theoretical basis of the economic efficiency of production and classifies the performance figures of beef cattle husbandry. Objectives. The article aims to define a system of indicators of beef cattle husbandry economic efficiency. Methods. For the study, we used a comparative analysis. Conclusions and Relevance. To assess the economic efficiency of agriculture production, it is necessary to use a set of indicators by beef cattle breeding sub-sector. The system of economic performance indicators of production needs to be transformed into a summarizing indicator. The results of the study can be applied in the theory and practice of determining the economic efficiency of the beef cattle industry.

While the development of the country's national innovation system as a whole is very important and should be prioritized, its regional aspect is even more important. The specifics of the Russian Federation's transition to an innovation-based economy is in that that, at the present time, prioritized is the need to ensure the effective development of those economy sectors that underlie the country's specialization and may provide regional and national competitive advantages. To such sectors belong the chemical industry, machine-building and power energetics. We would like to note that initial innovation awareness indicators in the regions are comparable and do not differ greatly but the growth of activity can be observed only in some of the regions. The problem of large differentiation among the constituent entities of the Russian Federation by their level of economic development remains important and has to be dealt with.
