What is history matching in reservoir simulation?
History matching is an important phase in reservoir modeling and simulation process, where one aims to find a reservoir description that minimizes difference between the observed performance and the simulator output during historic production period.
How is history matching done?
History matching in its essence is the selection of reservoir models which best match the reservoir data (static and dynamic). In traditional approaches, screening is often performed by a geo-scientist, who selects only a single model without considering the historical production (only static data).
What is history matching in oil industry?
History matching is defined as the act of adjusting a model of a reservoir until it closely reproduces the past behavior of a reservoir; this is a common practice in oil and gas industry in order to have reasonable future predictions.
What is reservoir simulation in petroleum engineering?
Reservoir simulation is an area of reservoir engineering in which computer models are used to predict the flow of fluids (typically, oil, water, and gas) through porous media.
What are the types of reservoir simulation?
Types of reservoir simulation models
- Black-oil.
- Compositional.
- Thermal.
- Single-porosity or dual-porosity (for fractured reservoirs)
What is reservoir simulation techniques?
Reservoir Simulation is a field developed in petroleum engineering where it utilizes porous media in computer modeling to estimate the fluids dynamics, its goal is to predict the field performance under varies producing strategies.
What are the main objectives of reservoir simulation?
The purpose of reservoir simulation is to predict field performance and ultimate recovery for various field development scenarios to evaluate the effects on recovery of different operational conditions and compare economics of different recovery methods.
What is a compositional simulator?
A compositional simulator is the most mechanistically accurate simulator for solvent compositional processes. When the EOS is tuned properly to appropriate experimental data, it computes realistic phase behavior. A compositional simulation can have other aspects of mechanistic reality besides phase behavior.
What studies can be done with reservoir simulation?
Reservoir simulators can be used to perform a variety of analyses. The primary uses of simulators include predicting production performance of the CBM reservoirs under various reservoir management strategies, estimating the ultimate gas recovery, and designing the most effective well completions.
Why do we need reservoir simulation?
How is reservoir simulation different from reservoir Modelling?
Although the model itself obviously lacks the reality of the reservoir, the behavior of a valid model simulates—assumes the appearance of—the actual reservoir. The purpose of simulation is estimation of field performance (e.g., oil recovery) under one or more producing schemes.
Why do we simulate reservoir?
Reservoir simulation is used extensively to identify opportunities to increase oil production in heavy oil deposits. Oil recovery is improved by lowering the oil viscosity by injecting steam or hot water.
