ABSTRACT
Oil is an industry that involves geology, chemistry, biology, physics, and fluid dynamics, all sorts of types of engineering, economics, politics, sociology, diplomacy, environmental sciences and more. When the industry started the way to find oil was to smell it, look for "salt domes," look at what the other oil prospectors were doing and where, and drilling a hole in the ground, usually on land not at sea, and usually just straight vertically and hope for the best. There are many types of oil. This is another element of the complexity of future problems and opportunities in oil production. Some of the more massive sources of oil that could be used in the future are called unconventional oils. Unconventional oils generally cost more to extract and process into usable liquid fuels than conventional oil. The climate will turn out is really quite a great source of uncertainty at many levels for the future supply of oil.
