The production of oil is decreasing. This is true at nearly all of the leading global oil companies. The reserves of these companies are also decreasing. These companies have therefore no other option but to expand their exploration in order to find new petroleum fields and to increase their production. Trillions of dollars may be exhausted in the next 15 to 20 years in their pursuit of oil and gas.

Let us take a look at 5 of the leading global oil companies.

Saudi Arabian Oil Company

Saudi Aramco is the state-owned domestic oil company of the Kingdom of Saudi Arabia. Aramco is an acronym for the Arabian American Oil Company. It is probably the world's biggest company in terms of verified petroleum reserves and output. The company's headquarters is located in Dhahran, Saudi Arabia.

National Iranian Oil Company

The National Iranian Oil Company is believed to be the second biggest petroleum company in the world. It was founded in 1948 and is involved with the exploration, production and sales of petroleum and natural gas. Its main office is in Tehran, the capital of Iran.

Qatar Petroleum

Qatar Petroleum is presently the third largest oil company in the world because of its oil and gas stockpiles. It is situated in Qatar and is involved with the exploration, production, refinement and storage of petroleum.

Abu Dhabi National Oil Company

The Abu Dhabi National Oil Company is among the world's leading oil companies with major stockpiles. It is a state-owned company of the United Arab Emirates. It is a fully integrated company and their processes include all aspects of working in the petroleum industry.

Petróleos de Venezuela South America

Petróleos de Venezuela is a crude oil company owned by the Venezuelan state. It has activities in exploring, producing and exporting oil and natural gas. It predominates the oil business of the Republic of Venezuela.

Oil answers for a significant percentage of the world's energy needs. Crude oil is critical to numerous industries and is necessary to sustain an industrialized society.

There are thousands of job vacancies in the oil industry! Don't know where to start? How to get a job on an offshore oil rig

According to basic data provided by the Energy Information Administration, the total world output is 95 trillion cubic feet of natural gas. The major producers are the US and the Gulf countries. The US accounts for one-fifth of the production.

Natural gas is produced in gas and oil fields, which are conventional sources, and coalfields, which are non-conventional. Conventional sources have higher gas recovery rates than non-conventional sources. According to the National Assessment of Oil and Gas fact sheet, 94 percent of natural gas is produced from conventional sources. Gas wells account for two-thirds of the production, and the remaining comes from oil wells.

Natural gas is produced from wells, both in land and offshore locations such as the Gulf of Mexico. Natural gas production is concentrated in the lower 48 states. Texas is the largest producer of gas, and San Juan Basin is the top-producing field in the US. The number of wells in the US is approximately 393,000, out of which 68,000 wells are found in Texas and negligible number of wells in Missouri, Arizona, Nevada, and Maryland.

The production of gas has been enhanced by new drilling technologies, and the extraction losses are estimated at 3 percent of production. Production is hampered by weather conditions such as hurricanes, which stop the production in offshore fields and also result in the possible destruction of transmission pipelines. Hurricane Katrina is one such instance which disrupted the supply. The price decontrol measures by Federal Energy Regulation Commission have also stimulated the supply of gas.

The total proven reserves in the US are approximately 200 trillion cubic feet, which in its current demand pattern, may last for ten years. Furthermore, there are unexplored fields such as the Alaskan fields.

Natural Gas provides detailed information on Natural Gas, Natural Gas Generators, Natural Gas Prices, Natural Gas Production and more. Natural Gas is affiliated with Current Oil Prices.

Hydrogen fuel and kits allowing you to convert your car to run on water gain popularity as several sources claim the price of oil will reach $200/barrel by the end of the this year.

This means about $7 per gallon of gas - incredible but probably true.

So how can you avoid this future problem of paying so much for money?

* Sell your car and use public transportation

* Purchase a hybrid car

* Get better gas mileage using your current car

Sell your car and use public transportation. This could be very useful and easy to do for many people who live in a large Metropolis such as New Your City in the USA or Montreal, Canada. This option will not serve as a solution for people who depend on their car for numerous reasons such as: In existence public transportation available, long daily distances, obligation to drive to work / drive children to school.

Using public transportation is much cheaper than owning a personal automobile, unfortunately it is not always possible, good service is not guaranteed and most of the time it is simply inconvenient. Many cities and smaller town do not offer public transportation.

You could buy one of those hybrid cars - the inconvenience is a waste of at least $15 000 plus the registration, insurance and all the regular jam. Of course a hybrid would be more gas efficient then a 6 cylinder car or your favorite V8 truck... but than again, spending almost 20 K is not a possibility for many folks.

Get better gas mileage using your current car - this is most likely the best solution for you because: There are numerous ways of getting better gas mileage, you already own a car and most likely enjoy it a lot (that's why you bought it in the first place, right) it is far more comfortable and more convenient than using public transportation.

So what can you do to get the best gas mileage?

Let's start with the basics:

* Accelerate gently. Sudden accelerations waste A LOT of gas.

* Keep your distance in order to avoid breaking and acceleration

* Try keeping your speed constant, use cruise control is available/possible

* Keep your car maintained; a simple oil change and suggested pressure in all four tires will save you gas and money.

* Try to avoid congested highways, when your engine is running but the car doesn't move you get Zero MPG.

Another thing you could do is convert your car to run on water. This method will allow you to save up to 75% of gas; in some case you will be able to DOUBLE your gas mileage.

As seen in a recent Fox News video report, water could be used as fuel in order increase the fuel economy and decrease the pollution. This new hydrogen-on-demand system will cost you under $200 dollars, it is easy to install, maintain and remove. Most importantly, it makes your engine run smoother and quieter, it cleans your engine and reduce the wear and tear of its parts, it equally reduces the pollution.

Thousands of drivers convert their car to use Water as fuel. It is cheap, simple and saves 1000's of dollars a year. This site will give you all the juicy details about converting your car to use this great fuel efficient system.

When you convert your car to run on water you are eligible for the IRS refunded applied to hybrid cars. Need more reasons for using the system?

- Your car gains power
- Your car longevity increases as this system cleans the engine
- You get a fuel economy increase of up to 75%, some users even reported 100% increase which means DOUBLE the mileage!

Unbelievable gas prices have slowly siphoned money from American wallets. The skyrocketing fuel prices not only affects individual Americans. It also affects businesses that rely on shipping product to one place to another.

Escalating fuel costs might even threaten some tourist destinations, like Disney World or Cedar Point. Not only will you have to pay a fortune traveling around in your car. You have to expect higher cost at your travel destination.

It seems now that warmer weather has eclipsed most of the nation. Our gasoline prices have risen out of control. Would we be paying $3.50 a gallon if this was December? I hardly doubt it. It is a lack of responsibility by our elected officials. Americans are being taken advantage, by the ruthless oil tycoons.

I am tired of not getting the same amount of gas that I used to receive. Heck, ten bucks might get me a quarter of a tank, if I am lucky.

I want to know where is my congressman. Why has legislation not been introduced to help ease our pain at the pump. It is sickening to hear of record profits reported every quarter, from the oil companies.

Imagine if the entire nation stopped pumping gas for just one day. Maybe the oil companies would sympathize with us, if just for a moment.

I would hope that there is not an American running any of the big oil companies. I know that's not true but it would be nice. Everytime I have to fill up I feel the money in my wallet has wings and just keeps flying away toward the Middle East.

I am trying to raise a family and this extra dent in my wallet is not helping matters, it is why I took matters into my own hands.

It is why I began researching fuel saving techniques. Might as well get as much mileage as possible per gallon.

I have actually found some incredible tips and methods for making my fillup last longer. I also found some great resources right here on the internet, that help ease the pain at the pump.

I learned the secret of turning the hose 180 degrees and letting that extra half cup of gas run into my tank, instead of the next customers tank.

I found that if you excellerate before you go up a hill it will add to your fuel economy.

You might want to check this out if you are tired of paying high prices at the pump. My methods and tips are sure to make your dollar stretch a little further.
