containing reservoirs that hold natural gas or

oil. An group of underground lakes.

8. Reservoir

A natural ly occurr ing storage area,

characteristically a folded rock formation,

that traps and holds natural gas or o il. An

underground lake of oil and gas.

A Plankton and algae, proteins and the li fe

that's floating in the sea, as it dies, falls to

the bottom, and these organisms are going

to be the source of our oi l and gas. When

they're buried with the accumulating

sediment and reach an adequate

temperature, something above 50 to 70C

they start to cook. This transformation, this

change, changes them in to the liquid

hydrocarbons that move and migrate, will

become our oil and gas reservoir.
