A Brief Overview Of Oil Exploration

When people talk about digging for oil, they usually mean the oil derived product called petroleum. It is a type of crude oil resultant that is widely utilized all over the world as a fuel source. The exact chemical composition of petroleum and its ratio of lighter to heavier hydrocarbons vary from one oil field to another. Only after the shipping product has gone through general refinement does it become relatively uniform.

The modern industrial world has an almost insatiable thirst for oil. So much of our power and economic infrastructure is tied up with oil and all its derivatives. Two of its more major uses include power generation and fuel for transportation. Many electrical power plants today still use oil as their main source of combustible fuel. In addition, virtually every major source of speedy mass transportation runs on petroleum gasoline. Absence of oil can bring any major metropolitan area to a dead stop. Nothing would work and no one can move.

This high demand has affected the global price for petroleum-based and dependent products. The increase in cost for oil usually has a domino effect that ultimately impacts every sector, level and niche of an economic system. More expensive petroleum would inevitably lead to more expensive food, transportation costs, utility bills, and others.

Oil exploration is the term used to denote the active search for more sources of oil by corporate or government entities. They are usually divided into two categories based on location.

On-shore oil exploration involves searching for hydrocarbon deposits on land. There’s a plethora of companies active in this field because of the high risk–reward ratio involved. Some on-shore drilling facilities can cost as little as a $100,000 dollars; this is a relatively cheap price considering the enormous economic value of actually finding oil.

Off-shore oil exploration is a very dangerous and difficult process. Only governments and especially large companies have the resources necessary to construct and operate an off-shore oil rig. Shallow water facilities can cost anywhere from $10 to $30 million dollars. Deep ocean deposits, which hold staggering amounts of petroleum, usually cost up to a $100 million dollars. This large expense is offset by the amount of enormously valuable oil that can be produced.
