At the moment, the world is hugely reliant on petroleum sources of energy. Almost every process that human beings engage in involves some level of use of petroleum energy. In fact, there are some countries whose entire economies are dependent on petroleum products. That is why a slight change in the prices of oil and oil products usually causes a rippling effect in the world economy.
Because of the high dependence on petroleum products, studies are still being carried out to develop effective methods of extraction. The aim of the studies is to find ways of exploiting oil while keeping costs down. Fracking is among the methods that have been developed recently to help in oil extraction. Although the technique is very efficient, efforts for achieving clean fracking technology are still being made.
The word fracking is the shortened version of hydrauling fracturing, a procedure in which chemicals, sand and water are injected underground in order to fracture layers of rock to give access to the oil. A very high pressure is employed in pumping the mixture of chemicals, sand and water in order to yield the force needed in cracking layers of rock.
Hydrofacturing, facing and hydrofracturing are other terms used in reference to fracking technology. The mixture of water, chemicals and sand is called fracking fluid. Upon creation of the fractures using fracking fluid, natural gas, petroleum and brine flow freely. The created cracks remain open after removal of hydraulic pressure because tiny hydraulic fracturing proppants keep them open.
Even though the process of fraccing only became popular in the mid-2000s, it has a very long history that dates several decades back. This technology has been in use in the oil industry as back as 1949. It was used to increase flow of gas in wells in places like Kansas. However, in 2000s, oil companies in the United States find ways of combing fraccing with horizontal drilling to extract oil at a reasonable cost.
Chemicals are heavily used in this whole process. Therefore, the process cannot be categorized as being environmentally friendly. However, efforts are being made to make it more environmentally friendly. Among the ways of reducing pollution is the use of additives that reduce friction. Research shows that this method allows for the use of brine or recycled water.
During extraction of oil, the processes of pumping and drilling employ heavy equipment that run on diesel engines. These engines release a lot of harmful pollutants and carbon into the air. In order to make the process notably cleaner, cleaner energy sources or natural gas can be used in place of diesel to power the engines. Natural gas has the capacity of reducing costs by nearly 40 percent.
One of the major concerns in oil extraction sites is emission of methane. It was found recently that too much of methane gas is released into the air. Actually, studies found that over 50 percent of methane is released into the air than the official approximations the US government had provided before. This process can be cleaner if ways of reducing release of methane gas are found.
