UNISIM is a research group linked to the Center for Energy and Petroleum Studies (CEPETRO) and the School of Mechanical Engineering (Department of Energy) at UNICAMP and its main objectives are:
- Improve the decision-making process in reservoir management based on models and data for oil production and CO2 storage;
- Training of human resources in the area of simulation and reservoir management;
- Improve reliability in model-based studies for managing oil reservoirs and CO2 storage; and
- Integration with other E&P areas: geosciences, production engineering, data sciences and economic evaluation.
UNISIM has carried out research into the study of simulator construction techniques, development and management of reservoirs, use of simulators to characterize reservoirs, automation of tasks that use simulators and the use of parallel and distributed computing techniques applied to the above processes.
The main research lines are:
- Integration of reservoir simulation with reservoir characterization:
- Representation of reservoirs in simulation models;
- Upscaling techniques;
- Creation of benchmarks representative of Brazilian fields;
- Model calibration techniques with dynamic data (data assimilation):
- Uncertainty reduction;
