Reserves Evaluation and Field Development Forecast for Previous HitUnconventionalNext Hit Oil in Western Siberia

Abstract

Abstract

Russia is expected to have world biggest Previous HitunconventionalNext Hit reserves in the world. There are several major Previous HitunconventionalNext Hit plays on the territory of Russian Federation. The question of determining reserves in Previous HitunconventionalNext Hit plays is quite important for project success. Main peculiarities of Previous HitunconventionalNext Hit reserves evaluation are relates to the following issues: no defined trap, no reservoir with measured properties that can be mapped, short-term test only results in a rate but not meaningful pressure needed to determine commercial feasibility of the project, no known fluid contact, highly variable well performance even within the sweet spots.

The paper is focused on the new method of empirical assessment of estimated ultimate recovery per well that leads to the evaluation of the recoverable reserves of the Previous HitunconventionalNext Hit project. This method can be used for optimizing of well spacing, well completion and fracturing strategy as well as operator's performance.

Nevertheless, many similarities exist in general for the Previous HitunconventionalNext Hit plays in North America and Russia, it is not possible to apply American experience straightforward to Russia. It proven to fail many times. Comparison of American and Russian Previous HitunconventionalNext Hit industry and local specifics is covered in this paper.

The proposed method was used for tight oil field development optimization in Western Siberia. The paper discusses practical aspects of proposed technology and its implementation for Previous HitunconventionalNext Hit projects evaluation and screening.
