A semisubmersible oil production platform operating in water 1,800 metres (6,000 feet) deep in the Campos basin, off the coast of Rio de Janeiro state, Brazil.
Reservoir engineers forecast the performance of an oil or gas reservoir by analyzing the physics of fluid flow through porous rock, accounting for hydrodynamic, thermodynamic, and gravitational forces.1
To achieve this, they collaborate with geoscientists and other engineers to develop a dynamic model of the reservoir. This process involves:1
- Static Modeling: Creating a map of the reservoir’s geological structure, stratigraphy, and deposition.1
- Data Integration: Incorporating fluid properties, reservoir pressures, temperatures, and existing well data.1
- Statistical Analysis: Using statistics to smooth trends and address uncertainties within the model.1
- Simulation: Utilizing reservoir simulators to construct various production scenarios, such as enhanced recovery, infrastructure changes, or price fluctuations.1
The final output of this dynamic model is a production forecast for oil, water, and gas, which helps teams minimize risks and uncertainties throughout the life of the project. These forecasts are essential for determining reserves, which are the portions of resources that are economically and technologically feasible to extract.12
