Products from HPHT Drilling: Natural Gas
HPHT drilling, also known as high pressure/high temperature drilling, is the process by which petroleum companies access natural resources well below the surface of the earth. And while crude oil is the product most often linked to deep well drilling, most of the natural gas the industrialized world uses also comes from these drilling procedures. Just like crude oil, natural gas is refined after extraction in order to produce a number of different materials. The natural gas used to heat a home for example, is the final, pure product resulting from the refining process.
Natural gas is most often found in deposits that are associated with other fossil fuels such as crude oil and coal. It is naturally produced in one of two ways; methanogenic or thermogenic. The methanogenic process involves living organisms found in bogs, swamps, and landfills, consuming the materials around them and producing natural gas. Thermogenic production is the result of the deteriorating organic material below the surface of the earth in a high pressure environment. Thermogenic natural gas provides the vast majority of what we use today.
Once natural gas is extracted through HPHT drilling or other means, it must undergo a refining process before it is usable. For residential purposes such as heating and cooking, the gas must be purged of all materials except methane. Methane is the highly flammable and odourless gas we use in our homes. However, the refining process also produces other things like ethane, propane, butane, helium, and nitrogen.
In addition to residential uses, we find natural gas put to work for commercial and industrial purposes as well. Power plants for example, require a source of energy in order to produce electricity. Some are powered with coal, others through nuclear technology, and still others with natural gas. In fact, the electrical needs of the world are so vast, it is essential for power companies to have as many options available to them for production. With natural gas as abundant in supply as it is, it promises to continue being one of the sources of electrical generation for years to come.
Other uses of natural gas by-products include fertilizers for the agricultural industry and fuels for the transportation industry. LG gas has been in development for use as a car fuel for some time. In Russia, a prominent aircraft manufacturer has been working on plans since the 1970s to create an LP and hydrogen-based aircraft fuel.
As scientists learn more about natural gas and its capabilities, the possibilities for this natural resource are as vast as the human imagination. Thanks to petroleum companies willing to employ HPHT drilling, the world is able to tap the seemingly endless supply of natural gas.
