A reservoir is composed of rock types of varying reservoir quality that are systematically stacked, according to stratigraphic and diagenetic principles. The term was basically defined by Henry Darcy, who showed that the common mathematics of heat transfer could be modified to adequately describe fluid flow in porous media. The main geologic characteristic of all the physical rock properties that have a bearing on reservoir behavior when producing oil and gas is the extreme variability in such properties within the reservoir itself, both laterally and vertically, and within short distances.

The need for reliable estimates of gross rock volume and original hydrocarbons in place, which are important for determining the economics of producing the reservoir, determining production facility requirements, ranking development opportunities of alternative reservoirs, and allocating equity shares with partners. To create a valley-dammed reservoir, the river that will fill the reservoir must be diverted, so the ground can be cleared to lay a foundation for the dam.

Infoplease knows the value of having sources you can trust. The dynamic behavior of the facies is assessed by studying the rock texture, the diagenetic processes which overprinted the initial fabric, and the interaction between the rock itself and the fluids. The manner in which they were derived creates essential differences as it relates to an earlier discussion of the fundamental properties of porosity and permeability.
