Tight reservoirs start to play increasingly more important role in petroleum industry. However, quality of the most part of the 3D reservoir models created in Russia does not allow a trustworthy reservoir characterization and their development optimization. This circumstance is one of the causes for rather low recovery factors in the territory of the RF. To significantly improve the quality of those models production logging data is to be more widely used in reservoir simulation. Recovery enhancement activities become much more efficient when based on reliable reservoir development models.

With specific reference to simulation of one of the “Gazprom neft” tight fields, the paper shows how the integration of welltest data in 3D simulation results in more confident modeling and improves the current oil production and ultimate oil recovery. In addition, some particular features were identified in the course of the work and new approaches were developed to solve tight reservoir simulation issues.
