What is reservoir characterization?

Reservoir characterization is defined as the model that characterises the reservoirs based on its ability to store and produce hydrocarbons. They are used to indicate the reservoir fluids behaviour under different circumstances and to find the optimal production techniques that are able to maximise production.

What is reservoir characterization and of what importance is it in petroleum data management?

The first aim of reservoir characterization is to produce a geological model that honors the available data and can be used to predict the distribution of porosity, permeability, and fluids throughout the field (Geehan and Pearce, 1994).

What are the main objectives of reservoir performance analysis?

Minimizing the Uncertainty of Well Trajectory Calculations.

What are the factors affecting the reservoir fluid properties?

Petroleum reservoirs may contain any of the three fluid phases—water (brine), oil, or gas. The initial distribution of phases depends on depth, temperature, pressure, composition, historical migration, type of geological trap, and reservoir heterogeneity (that is, varying rock properties).

What is reservoir simulation technique?

Reservoir simulation is an area of reservoir engineering where computer models are used to predict flow of fluids through porous media. In EnKF method, static parameters like porosity, permeability and dynamic variables are updated to match with real-time production data.

What are the three components of reservoir simulation study?

Traditional finite difference simulators dominate both theoretical and practical work in reservoir simulation. Conventional FD simulation is underpinned by three physical concepts: conservation of mass, isothermal fluid phase behavior, and the Darcy approximation of fluid flow through porous media.

What is reservoir analysis?

Reservoir analysis develops subsurface data to integrate analysis of rocks, pores, and fluids from various reservoirs. In addition, it calculates dynamic rock and fluid properties and gives reservoir model indirect measurements.

What is reservoir performance analysis?

Reservoir performance affects the economic viability of a play or prospect and is a function of reservoir system quality. Performance is expressed by. Initial production rate and production rate decline over time. The percentage of hydrocarbon recovered from the hydrocarbon originally in place (recovery factor)
