The requirements for the quality of reservoir models are constantly increasing. Therefore the requirements for reservoir simulation software are increasing as well. Up-to-date simulators should keep up with very large models, they should use high performance computing and support sector modelling option – these features speed up computations up to dozens of times. It is also necessary to take into account all important physical phenomena and provide users with wide variety of tools for pre- and post-processing. Simulators should automate such processes as geological model examination and all initial data check – it helps to improve model quality and saves time spent on preprocessing.

The corporate reservoir simulator TecScheme has been used as the main simulation tool in Surgutneftegas OJSC for more than 20 years. It was used for simulation of the major oil fields of the company. Its performance has been increased significantly: improved convergence of the linear solver for complex 3-phase models, supported option of sector modelling, the variety of well constraints added as well as the new features for hard-to-recover reserves. Development of TecScheme helps to decrease spending on expensive foreign software and dependency on it. Now such new features as geological modelling tools and automated history matching are being developed.
