Hydraulic fracturing or fracking as it is often referred to is a subject that has generated and continues to generate much interest and debate particularly in the fields of energy generation and environmental protection. For those who are inquisitive about the technicalities and repercussions of this process, which involves fracking, they have come to the right place. In this article, we will start with the definition of fracking-also referred to as hydraulic fracturing, its operational approach, and how technological progress has infused in this practice. The environmental as well economic dimensions have also been looked into so as to give the reader a more complete picture of this technology and how one can responsibly utilize it.
Let’s start from the beginning: what exactly is fracking?
Fracking refers to extracting gas or oil from beneath the earth’s crust by employing some deep mining techniques. It entails drilling vertically into the earth body and injecting a high pressure mixture of water, sand and chemicals into a rock stratum. This causes the rock to fracture and gas or oil that is within the rock formation becomes liberated and flows into the wellbore where it is collected at the surface.
The idea may appear simple at first, however, the technical and scientific aspects of the hydraulic fracturing are far simpler. Fracking has its roots back in the 1940s, but for picture courtesy of the current technology, it has undergone amazing changes over the years. Such changes, however, have had negative environmental impacts that are equally evident.
How Fracking Works: A Technological Breakdown
Drilling and Well Construction
The initial process includes completing a hole in the earth from which the oil or gas has to be recovered, and this involves drilling a well. This is done with the help of a rotary drill which drills a cylindrical hole deep into the surface oftentimes reaching up to between 1 and 2 miles deep. When this depth has been attained, the bore hole is turned and drilled parallel to the shale rock structure in which oil and gas is trapped.
Fracturing Fluid Injection
Once the well is in place, it is filled with a, water, sand and chemicals in the form of a slurry under very high pressure. The pressure is too much that rocks around the bore hole are ruptured with cracks being formed through which gas or oil is trapped. The sand in the mixture is used to prop these fissures open to allow continuous resource flow.
Focusing on Extraction and Recovery
Once the fractures are formed, the increasing pressure is relieved enabling the oil or gas to be let from the well at the rig. The resulting fluid that is flowbacked is also managed with regulatory effective means once it is recovered.
Fracking Technology
The scope and methods of fracking technology have been improved with high technology. The factors like better seismic imaging and real-time drilling monitoring have been showing promising outcomes enhancing the accuracy of drilling and therefore minimize harm to the surrounding environment. Furthermore, there has been the invention of slickwater fracking, which is the utilization of chemicals to lower the friction during fracking to improve the process which has enabled fracking in tough resource formations.
The Effect of Fracking: Economic Growth at the Cost of the Environment?
There is no doubt that fracking has enhanced the economy of different areas including United States regions. It has stimulated the increase in production of natural gas, decreased energy prices as well as reduced dependence on foreign sources of petroleum. However, this trade-off is that great economic advantage has been accompanied by adverse environmental impacts.
Main Issues Facing the Environment
Fracking carries foremost dangers due to the risk of fracking contaminating the groundwater, which is one of the risks. The chemical agents present within the fracturing fluids could infiltrate the underground sources, endangering the water for consumption. In addition, water is so greatly needed for fracking that it causes depletion of water sources in any local area especially in countries prone to drought.
Methane emissions are also a cause for concern because they are released during the extraction processes and they maintain heat in the atmosphere. Natural gas is cleaner than coal even if you burn it albeit there are methane leaks as a fracking downside to the environment.
Moreover, most studies show that consequent to fracking there has been increased seismic activity. The practice of injecting wastewater into deep underground wells, which is associated with fracking activities, has been the reason for several minor earthquakes occurring in some places.
Regulatory and Technological Responses
In light of these concerns, call for more stringent regulations and implementation of cleaner fracking technologies have emerged. For example, the last two decades have seen some improvements in designs of the wells ruining the e methane, preventing any damages to the environment. Instances of non-toxic fracturing fluids have been also adopted as a way of improving good hydraulic fracking practices.
Tips to Implement Fracking Policies
Keep track of the changing fracking: With each passing day, new technologies are being employed, and regulations related to fracking are being restructured or introduced. Keeping track of how fracking is taking shape will assist you to appreciate such ideas further and help you in your decision making.
Act to reduce the harm caused by fracking: If you work in or are about to commit your funds in the energy sector, do some due diligence to identify corporations that are eco-friendly. Supporting such corporations and investing in the Green-Growth Technologies will go a long way in reducing the adverse effects of fracking.
Seek Information: A call for information to be made conscious in the fracking industry. Understanding the chemicals in the fracturing fluid, and the total environmental impacts of the fracking process from all companies is very essential in protecting people and the ecosystems.
Propose Other Energy Sources: This is because even though fracking has been described as a great contribution to the energy needs, other forms of energy should be considered for use. Transitioning to renewable energy resources and working to advance policies that encourage it will help alleviate dependency on oil.
Conclusion: The Future of Fracking
Fracking appears to be a double-edged sword. To begin with, it has changed the energy sector entirely by allowing quick access to the enormous oil and natural gas reserves that were out of reach in the past. While on the other side, it brings about the fracking related risks and worries which can be simply ignored.
As physics progresses, it is probable that fracking will become even more effective and eco-friendly methods of natural gas extraction developed. But for this, active participation is required from all actors in the industry, regulators, and society to be able to harness the advantages of fracking without incurring a proportional cost.
Whether one sees fracking as an evil on the other side railing or history in the making, there is one criterion that must be taken into consideration: it is with certainty that in the near foreseeable future this will have a positive and negative influence in our energy history landscape. The target is clear – to construct useful, advanced and environmentally friendly fracking technologies.
