Abstract

The article presents strategies for prompt selection of candidates for sidetracking and horizontal sidetracking, which allow choosing the best formation zones for drilling. Modern software systems, such as IS "RN-KIN", make it possible to build up various assessment maps and look at the complex situation of an oil production facility. The most effective approach to finding candidates for sidetracking and horizontal sidetracking is the construction of a full-scale 3D reservoir simulation model and the location of the design boreholes according to the maps of residual recoverable reserves. However, in practice, there is not always the possibility and times for constructing models; therefore, the authors have developed a methodology for selecting candidates without constructing and adapting the reservoir simulation model. The main idea of the technique is to build a map for assessing the energy state of the reservoir based on changes in reservoir pressure during development, which allows you to determine the sections of the reservoir that are not involved in development. The complex map uses a number of criteria that take into account both accumulated and current well performance. The proposed approach has been tested in the fields of Western Siberia of various producing companies and has shown its applicability.

Key words:

sidetracking, prompt selection of candidates, search for stagnant formation zones
