The Group

UNISIM is a research group, created in 1996, that operates in the Numerical Simulation and Management of Petroleum Reservoirs. The group belongs to the Department of Petroleum Engineering of the Faculty of Mechanical Engineering at UNICAMP, and has the support of the Center for Petroleum Studies (CEPETRO).

Mission

UNISIM has the main mission of teaching and research into reservoir simulation and management of oil and gas reservoirs.
 

Objective

 

Research

The research developed by the group includes the main activities related to the decision analysis process focused on the development and management of oil fields using reservoir simulation.
The main research lines of the group are:
  • Integration with reservoir characterization: The objective of this line is the representation of rock and fluid properties in simulators, including the treatment of uncertainties. Studies about the estimation of the value of information, the integration with 4D seismic and the building of benchmark cases are also included in this line.
  • Simulation techniques: This line involves the construction of simulation models aiming their reliability for the study of oil production process, including techniques such as meta-models or emulators.
  • History matching: The development of calibration techniques models through dynamic data, involving assisted history matching processes, probabilistic approaches and real time matching are included in this line.
  • Decision analysis: This line involves the decision-making process for development and management of oil fields, addressing optimization of exploitation, selection strategies under uncertainty, risk analysis, smart fields, flexibility and robustness value and integration with production systems.
  • Reservoir applications: Oriented to the study of the pre-salt carbonate reservoirs, heavy oil reservoirs, naturally and hydraulically fractured reservoirs, mature fields, multi-reservoir simulations, WAG processes and polymer injection.
  • Auxiliary techniques: This line includes optimization methods, parallel computing, integration with economic evaluation (including different tax schemes in Brazil) and modeling of production systems.
The group also aims to create methodologies and task automation processes for the development and management of reservoirs oil by the development of computational tools integrated to the main current commercial simulators.
