Fracking, also known as hydraulic fracturing, is the controversial process of forcing water, gases, chemicals and other materials deep underground to fracture rock layers and free up the gas and oil trapped there.
The process has created an oil and natural gas boom in North America and has put the United States on the road to reducing or even ending its energy dependence. However, its potential to contaminate ground water supplies and cause long-term pollution has also earned it a lot of opponents.
That is changing, however. The Wall Street Journal recently ran a lengthy article on how energy companies are using new fracking methods that not only protect fresh water supplies but also recycle and dispose of waste water, while coming up with more efficient ways to conserve natural gas that was previously lost in the overall fracking process.

Along with the usual suspects – the energy companies like Anadarko Petroleum (NYSE: APC), Schlumberger Limited (NYSE: SLB) and service providers like Halliburton (NYSE: HAL) – there are a slew of other companies that stand to benefit from the fracking boom. Here are a few of them:
Fracking Technologies
General Electric (NYSE: GE)
Someone has to develop the latest technologies needed for fracking – and GE has been pioneering some innovative ways to use carbon dioxide in the fracking process. Reuters reported the conglomerate is working with the Norwegian energy company Statoil (NYSE: STO) in a $10 billion program researching the use of chilled CO2 in fracking, as part of a less environmentally-invasive and more cost-efficient process.
"Our ultimate vision is to have a fracking process that uses no water,” GE mechanical engineer Andrew Gorton told the wire service, “but we're a ways off from that.”
The chilled CO2 process would reportedly help reduce greenhouse gas emissions while producing more oil and natural gas during fracking. The increased yield results from the higher pressure created by carbon dioxide compared to injected water.

GasFrac Energy Services (OTC: GSFVF)
On its web site, this Calgary-based company says it can take the water out of fracking by using a liquefied petroleum gas (LPG) gel that is not only reusable but environmentally-safe. The proprietary material, according to Energy & Capital, can be extracted and resold on the market, compared to conventional fracking methods, where “more than 80 percent of the water and frac fluid stays in the rock formation.”

Rail Companies
Fracking has been a victim of its own success, logistics-wise. The regions where oil and natural gas are produced by fracking remain relatively isolated, and still do not have the pipeline infrastructure needed to simplify transport.
Rail has become essential for not only transporting oil released and extracted by fracking, but also to bring in the “frac sand” needed in the process.
"Rail is really integral to the whole [frac sand] industry," Thomas Woletz, senior manager at the Wisconsin Department of Natural Resources, told EnergyWire last summer. "If there is a bottleneck right now, it's from the transport infrastructure, not the lack of sand or mines. It's the lack of ability to get it out."
Several North American rail companies are finding new revenue resources via the fracking boom.
Union Pacific (NYSE: UNP)
According to Bloomberg, Union Pacific and U.S. Silica are creating a $12 million sand storage facility in Odessa, Texas.
BNSF Railway
Canadian National Railway (NYSE: CNI)
Last year, Canadian National Railway said it was expediting its $33 million upgrade to a stretch of track that runs through “prime frac sand territory” in west-central Wisconsin – by reportedly strengthening the tracks to handle heavier loads and faster trains. The project is expected to be completed this upcoming December – a year earlier than expected.
