The project approach for the entry of the promising areas in the development

Abstract

For now, the time of «light crude oil» has ended on the territory of the West Siberian oil and gas basin, which entails the reorientation of oil companies to search for non-involved areas in the perimeter of current assets and the use of new technologies to increase the profitability of development. The «Gazprom neft» NTC applies an integrated approach to solve these problems. Multidisciplinary teams have been created for each asset, where not only the specialists of the NTC, but also all the necessary services of the mining enterprise are involved in a single team. The article covers the features and mechanisms of this approach. The structure of the approach can be presented as successive interrelated stages, including a detailed geological study, based on conceptual modeling, data analysis and realization on their basis of multivariate calculations to determine the optimal development system. The next stages are adaptation of the selected system and the placement of the well stock at each perspective site, followed by variable calculation of development indicators and economic efficiency. The final stages are the preparation of the risk matrix, the implementation of the additional appraisal program and drilling technical support, according to the developed design logic. During the description of the entire process of planning and implementation of placing of new wells program, the main features and methods of solving the problems facing the engineering team were given, as well as the tools developed by the company to achieve the maximum speed of the calculations side by side with their high accuracy. The effectiveness of the multidisciplinary project approach is proved by the continuously decreasing number of inefficient investments, positive dynamics of confirmation of forecast indicators for wells in the «Gazprom neft» current assets, as well as the achievement (from 2015 to 2018) of an average flow rate increase of 37 %.
