Hydraulic fracturing has faced a great deal of criticism. In most cases, the criticism is due to the already existing shortage of clean water on earth. While some companies like GasFrac Canada are now using alternative frac waters, others need to do so. Although, excessive water use is not the only issue, drilling deep into the rock formation of earth has proved to be the cause of man-made earthquakes in different areas including, Texas and Oklahoma.
Regardless of such concerns, one company has introduced alternatives to water based operations. Developed by Canada-based GasFrac, the new process redefines the process by injecting liquids which are petroleum based deep into the earth rather than using chemical cocktails mixed with water. As a result, while seismic activity from the operations are still a concern, the new operation eliminates water table contamination.
Water-free fracking proponents try to support a theory that the process is a solution to water contamination and others related to the process. While this is the case, it is essential to look at the benefits and drawbacks of any new technology or process. With that being said, the benefits of waterless fracking currently appear to outweigh any drawbacks.
Perhaps the answer can be found in the way in which this type of fracturing works. For, the operation is the same as with hydraulic fracturing only with different liquids. Although, waterless fracturing operations first start by drilling a well. Once the desired formation of the well has been reached, horizontal drilling continues.
A well once complete, is then injected with propane or other chemicals by a carrier. The carrier fractures the base rock formation which allows oil and gas to escape to the surface. While GasFrac uses propane as a liquid, there are other alternatives, though propane does appear to be the most popular substitute for water.
Most often, liquid propane provides all the chemical aspects and benefits necessary to match that of water based operations. These benefits include, a more effective operation, the elimination of blockages in the well and the reversal of liquid propane to a gas form, which results in oil and gas flowing freely back to the surface.
Water-free fracking also helps to prevent pollutants from escaping to the surface. For, when a liquid version of propane vaporizes, the pollutants are left in the well. Whereas, operations which use water tend to carry these pollutants back to the surface, including chemicals used in the process and heavy metals which are a natural aspect of the rock formations which have been disturbed.
One of the biggest benefits in using propane is that liquid propane can be sold or recycled. In addition, once the process is complete, companies must dispose of produced water used during the operation. As a result, there has to be some place to release the polluted water, often causing polluted oceans and waterways. For, while there had been rules in place to prevent dumping of frac water into the ocean, environmental rollbacks have now allowed for a number of coastal locations in which companies can now do so.
