Natural phenomena in oil and gas fields

Accumulations of oil and gas are confined to natural traps, which are characterized by a complex internal structure, the fluid flow in which cannot be described within the framework of Darcy's law. When hydrocarbons penetrate into permeable sediments, heavy hydrocarbon fractions interact with porous media. The exploration and development systems used do not take these natural phenomena into account that causes a low completeness of oil and gas recovery and low reliability of oil and gas reserve estimates.
