Leading Fracking Companies Secure Their Futures

Fracking is a double-edged sword. On the one hand, it provides natural gas, a domestic energy source that is blissfully unscathed by volatility in unstable regions, and that has a lower carbon footprint than coal. On the other hand, fracking presents several risks that are as yet unresolved, among them, the potential for groundwater contamination and increased seismicity, and the looming problem of something called fugitive methane emissions.

Fracking, methane, and climate change
Let's talk about that last one. In terms of global-warming threats, methane makes carbon look like a mewling kitten, at least on a per-unit basis. While we emit far more carbon dioxide than methane, methane packs a much more potent wallop once it's out in the atmosphere.

In the case of natural gas extraction and transportation, enough methane leaks along the way that some people have argued that it cancels out whatever carbon savings we might realize by switching away from coal. Further still, natural gas and petroleum systems are the U.S.' biggest contributors to methane emissions. This could all pose a problem to the natural gas industry if ever our society gets serious about reining in its contribution to climate change.

Fortunately, some companies are demonstrating the prescience and initiative to get out in front of this issue. They have partnered with environmental NGOs and academic researchers to conduct robust scientific studies of the fugitive methane problem, seeking to identify its scope and its origins.

Anadarko Petroleum (NYSE: APC)Encana (NYSE: ECA), Pioneer Natural Resources (NYSE: PXD), Southwestern Energy (NYSE: SWN), and Talisman Energy (NYSE: TLM) funded and participated in a comprehensive research initiative organized by the Environmental Defense Fund, involving more than 90 partners -- universities, scientists, research facilities, and oil and gas companies. The study's results were published yesterday. It was the first in what will be a series of studies analyzing methane leakages along the natural gas supply chain. This first study focused strictly on the extraction phase.

The broad conclusion is that EPA estimates of methane emissions from natural gas extraction sites are largely accurate, meaning that the rules the agency promulgates are founded on accurate assumptions. However, a more granular reading of the study leads to some interesting takeaways, namely that some areas of extraction have far less of an impact than EPA thought, and others have far more.

The researchers found that well completions in the study group generated lower methane emissions than the EPA had estimated, probably because companies have been successful in their use of a control method known as a "green completion." Meanwhile, emissions are higher than EPA estimates for valve controllers, also called pneumatics, meaning that equipment leaks are an area where fracking companies have an opportunity to reduce methane emissions further.

So, then, fracking is fine, right?
None of this means that fracking just got a pass. Indeed, it's important to consider that the companies that participated in this study are a self-selecting group, and chose to opt in because they are aware of the risks, and are interested in mitigating them. It's highly likely that the general fracking landscape is far grimmer. But, that's something I can sink my teeth into as an investor. The companies that are engaged in this effort are essentially future-proofing themselves. They know that methane emissions are bad for business, and they are working to get leaks under control before regulators force them to do so.

An Anadarko spokesman said that the company now uses emissions control technology for all of its U.S. onshore well completions. Southwestern Energy put out a press release affirming its strong support for methane capture technology along the entire natural gas supply chain, and expressing enthusiasm for the next phase of the research. A spokesman for Pioneer Natural Resources expressed surprise at the finding that a lot of methane leaks from fracking operations that separate natural gas from oil and water as they bubble up from the well together, describing this as an area of focus for the company going forward .

Foolish bottom line
Fracking has come under a lot of fire over the course of the shale gas boom. While natural gas has rewarded investors handsomely, those gains are under constant threat as long as fracking continues to pose a risk -- whether real or perceived -- to human health and the environment. The companies involved in this study are demonstrating leadership by working to contain one such threat. In so doing, they are protecting their assets and securing the viability of their future revenue streams. That ought to make shareholders very happy.

Even as investors clue in to the sea change in our energy landscape, one home-run investing opportunity has still been slipping under Wall Street's radar for months. But it won't stay hidden much longer. Forward-thinking energy players like GE and Ford have already plowed sizable amounts of research capital into this little-known stock... because they know it holds the key to the explosive profit power of the coming "no choice fuel revolution." Luckily, there's still time for you to get on board if you act quickly. All the details are inside an exclusive report from The Motley Fool. Click here for the full story!
