Construction of up-to-date reservoir models depends on the input data, the quality of the geologic, geophysical and petrophysical field data, as well as utilized technology.

In case of limited or poor geological and petrophysical data geological modeling could result in several different variants or reservoir model. When making a decision according to one of the possible variants all available data as well as regional geology and tectonic information of the region should be taken in account.

For the developing fields relevance of geological model is checked at the stage of hydrodynamic modeling when matching to history data. Work on the project in such cases consists of several iterations and implies specialized software and close collaboration between specialists. Advanced technologies have a wide range of modeling tools, which constantly evolve to ensure the speed and efficiency of their use. The Big Loop solution integrates static and dynamic model uncertainty under one streamlined workflow.
