The naturally occurring hydrocarbons, such as crude oil or natural gas, are trapped by overlying rock formations with lower permeability. Reservoirs are found using hydrocarbon exploration methods.

Famous quotes containing the word reservoir:

    It’s very expressive of myself. I just lump everything in a great heap which I have labeled “the past,” and, having thus emptied this deep reservoir that was once myself, I am ready to continue.
    Zelda Fitzgerald (1900–1948)
