The quest for green fracking fluids
Some companies believe they are on the verge of such a discovery. ExxonMobil ( ) , for instance, says it has developed a new generation of fracking fluids that don't pose a threat to the environment. While the oil major's newly developed concoction hasn't been tested in the field yet, the company assures us that it doesn't contain any toxic chemicals.
Similarly, Halliburton ( ) has developed a green fracking fluid that uses ingredients sourced from the food industry. Halliburton claims that the product, called CleanStim, provides an "extra margin of safety" to people, animals, and the environment in the event of a spill. To prove that the product is truly harmless, a Halliburton executive actually took a sip of CleanStim during an industry event last year.
Besides the companies that actually do the fracking, smaller specialist firms are also making impressive strides in greening the fracking process. For instance, Austin, Texas-based Chem Rock Technologies has developed fracking fluids that it claims do not pose a threat to water supplies even in the event of a spill, while Rapid Drilling Fluids, also based in Austin, has developed biodegradable drilling fluids.Read the whole article by clicking here.
