Kasimova and Alexander K. Moskalev* Siberian Federal University 79 Svobodny, Krasnoyarsk, 660041, Russia Received 22.10.2015, received in revised form 18.01.2016, accepted 27.02.2016 The article presents the results of a search for an adequate method of assessing economic effi ciency of an innovative oil deposit development project offered for investment. <...> The tools currently used for project assessment are seen as insuffi cient, and the results they provide are not informative enough for investment decision-making. <...> The currently used methods do not consider the impact made by external and internal risk factors on the ultimate effi ciency value; therefore, the investment effi ciency assessment problem still remains urgent. <...> One of the ways to solve the problem is to apply Monte Carlo simulation method for the investment effi ciency analysis. <...> The research analyses a real project for reservoir pressure maintenance system pumping units used in oil deposit development. <...> In order to prove the accuracy of the obtained results and the effi ciency of the assessment tool, the data were compared to the ones calculated with a method where the main effi ciency indicator is net present value. <...> The research results lead us to conclusion on the appropriateness of using such additional investment project selection tools as Monte Carlo method, along with the traditional ones. <...> Keywords: investment, economic effi ciency, net present value, Monte Carlo method. <...> Introduction For any oil and gas extracting company the main course of new technical solution development is the work on the economical deposit development problem. <...> Today there is a great number of works written by both Russian and foreign authors devoted to the economic effi ciency assessment of innovative projects. <...> The main indicator of an innovative technology project’s attractiveness is economic effi ciency of the investment it requires. <...> All rights reserved * Corresponding author E-mail address: kafedra_efi t@mail.ru # 815 # approach to economic assessment of projects, where the main attractiveness criteria <...>
