Reservoir characterization review in sedimentary basins

Abstract

Evaluating the subsurface characteristics of reservoirs is an important part of gas storage, hydrocarbon exploration, and production in sedimentary basins. This process combines geological, geophysical, and engineering data to understand the subsurface geology, and fluid distribution, determine reserves and predict the fluid movement in the reservoir. And in the case of empty reservoir, the storage capacity, sealing strength is analysed. The primary goal of reservoir characterization is to create a precise and dependable reservoir model to maximize the production procedure and reduce the associated risks of hydrocarbon exploration and production. This review examines different approaches used for reservoir characterization in sedimentary basins, including geological, geophysical, and engineering methods. Each method's advantages and disadvantages are discussed, alongside their uses in different reservoir contexts. The importance of combining multiple lines of evidence to enhance the accuracy of the reservoir models is also examined.
