Reservoir Characterization, Modeling, Management and Evaluation

A reservoir model that includes all of the properties of the reservoir that are relevant to its potential to store and generate hydrocarbons. Reservoir characterization models are used to simulate the behavior of the fluids within the reservoir under a variety of conditions and to determine the most efficient production procedures. Reservoir characterization is an important step in the upstream industry as it allows companies to get the most out of their crude oil reserves.

A "reservoir model" is a mathematical description of a specific volume of rock that includes all of the reservoir's "characteristics." It can be thought of as a three-dimensional model of a single reservoir or, in some situations, an oil/gas field.

Reservoir management is commonly characterized as using resources to maximize hydrocarbon recovery from a reservoir while lowering capital and operating costs. It is based on the application of human, technological, and financial resources to maximize profits from a reservoir. Reservoir management must be viewed as a dynamic process aimed at detecting the uncertainties affecting future field behavior and attempting to mitigate their influence by maximizing field performance through the application of integrated, interdisciplinary technologies in a systematic manner.

Reservoir evaluation is a quantitative tool for identifying reservoirs and describing heterogeneity. Reservoir evaluation aims to subjectively and quantitatively evaluate the spatial distribution characteristics of shale reservoirs, as well as to simulate the storage and production status of gas in shale.
