Detailed Method for Static Modeling of Geobodies of Ozhginskoe Gas-Oil Field

It was found that for field development project with a complex geological structure prediction of reservoir distribution and well working design by standard static modeling methods not correctly. Often there are problems with water flooding and gas-oil ratio in wells adaptation, which are the main criteria for prediction as in this example.

In detailed static gas-oil field model the main depositional environment were identified and performed additional detailed reservoirs subdivision for better prediction well working in different parts of the field, for the drill planning, involved in development deposits and wells with maximum efficiency. Based on static model areas for drilling with maximum localization of residual mobile oil reserves were localized with compiling for each geobodies and reservoirs.

Incorrect understanding of deposits and volume of hydrocarbons leads to making wrong strategic decisions and reduce the economic viability of field development.
