What is Hydrofracking?
Hydrofracking is a technique where larger amounts of water, combined with smaller amounts of chemicals and sand, are pumped under high pressure into a drilled gas well. The main purpose to hydrofracking is to form tiny fractures in the rock by using water to force the rock open along tiny fractures that already exist. After the pressure is released, sand is left behind, opening the tiny fractures and allowing the gasses to escape more freely into the well.
Hydrofracking began as an experiment in 1947, but did not become a successful application until completed in 1950. The initial experiment took place in Kansas in 1947. Although, before water was introduced into the procedure, the companies used oil and other thick products to complete the fracturing job. Water was introduced to this process in 1953. Higher pressure and concentrations mean that more fractures are able to be opened, and more gas can be released from the well. Over 60% of all gas drilled wells have been achieved by hydrofracking.
The Downsides to Hydrofracking?
Although hydrofracking may sometimes seem like a convenient process, there are a few "cons".
* Hydrofracking can be prone to injuring the workers on the sites.
*The animals (livestock) surrounding the sites are in danger when being around the drills, chemicals, and equipment.
*This process is expensive.
*The future for hydrofracking has not yet been decided.
- Uses an extremely large amount of fresh water which can becom contaminated and highly toxic.
-The chemical mixtures are very hazardous.
-The natural gas recovered by fracking can be contaminated with methane.
- Can cause injury to the workers or animals near the sites.
The future effects of hydrofracking have not yet been estimated or determined because there has not yet been any long-term studies on the technique.
The Benefits of Hydrofracking
There are also a few "pros" of fracking:
*provides jobs and tax revenue
*improved national security
*few benefits to the environment
