Description

The Gulf oil situation is a tragic example that might have been prevented if drillers had been aware of how Earth creates its tremendous volumes of hydrocarbon fuels (gas, oil, coal). In brief: Methane gas molecules (CH4) trapped in Earth's crust polymerize (link together) to form petroleum. The degree of polymerization is a function of temperature, high pressure and time; as it progresses, the ratio of gas to oil decreases along with decreasing pressure, if not connected to a higher-pressured source of gas. When drilled into, the higher pressure can exceed the capability of the blow-out preventer.
