Exploring Hydrocarbon Depletion
Page added on April 4, 2012
Natural gas has been in the news a lot lately, being hailed as the solution to our energy problems on the one hand, and a potential environmental nightmare on the other. Let’s try to sort out the reality behind this old friend with a new face. Before we start, it might be useful to make a distinction between the natural gas that has historically been collected as a byproduct of oil drilling and the more recently promoted source known as shale gas. This has become newsworthy as the result of an enormous deposit of shale gas discovered in the Marcellus field extending across large sections of Pennsylvania, Maryland, and New York. Shale gas requires a much more aggressive method of collection since it is buried deep in the earth under many layers of shale. The most popular method of collecting shale gas is hydraulic fracturing, or fracking, a relatively new technology, developed by Halliburton, which has become quite controversial. The move into fracking parallels a gradual takeover of the natural gas industry by the big oil companies.
The relatively even number of pros and cons shows that this is not an easy choice. Given how widespread and available and “less bad” natural gas is from other fossil fuels, plus the number of jobs created, it is hard to ignore the argument that natural gas should serve as a bridge fuel as more sustainable alternatives are built out. We should keep in mind though, that it is a short term measure and invest accordingly. As far as fracking is concerned, considering that there is already lots of gas available right now, there is no reason (other than greed) to be in a hurry to develop shale gas. Instead, we should take whatever time is necessary to develop a safer, more responsible way to access that gas, while investing heavily in more sustainable sources that will ultimately obviate the need for it.
