The shale oil boom that began about 15 years ago enabled the fastest economic growth of oil and natural gas production in U.S. history.

Prior to the onset of the Covid-19 pandemic, the shale boom even enabled the USA to briefly achieve energy independence — something that was unthinkable 20 years ago.

The shale boom was enabled by the marriage of two technologies: Horizontal drilling and hydraulic fracturing. The combination is typically referred to as simply “fracking.” However, environmentalists have long contended that fracking threatens our water supplies.

An improperly fracked well could result in contamination. For example, if an oil formation was fracked in close proximity to a freshwater aquifer, it could result in a migration of fracking fluids or hydrocarbons into the drinking water.

There was a very well-documented case of an improperly cemented well-contaminating water in Dimock, Pennsylvania. In 2010, gas driller Cabot Oil & Gas was cited by the Pennsylvania Department of Environmental Protection for contaminating water wells with its Marcellus Shale drilling operations.

Last year, Pennsylvania Attorney General Josh Shapiro announced 15 criminal counts against Cabot, including nine felonies, upon the recommendation of a grand jury. The company was charged with violating the state’s Clean Streams Law.

The Cabot case provides a perfect example of why fracking became controversial. The reason the water wells were contaminated was determined to be the result of the improper cementing of the gas wells.

Fracking requires a lot of water. Millions of gallons of water can be required to frack a well, and that can make it especially challenging in arid climates. An ideal solution that addresses the issues around water would be a water-less fracking technique.

In fact, some work has been done in this area, but there hasn’t been widespread adoption of any technique that could replace, or even substantially complement fracking as a technique for completing a well.
