Shell Oil has announced plans to utilize hydraulic fracturing at two of its wells in northwest Colorado, Craig Daily Press reported.
The announcement came during a community open house event in Craig, Colo., on Monday.
Shell officials said the last year has been characterized by experimentation as the energy company launched a winter drilling program for the first time since it began exploring the Niobrara Shale formation for oil. That trend will continue as Shell will begin experimenting with fracking in mid-May.

“We’ve learned a lot about fracturing from some of our other projects and from the industry,” said Matt Holman, Shell Oil’s exploration project manager. “We have two dry holes, and we’re going to try some well stimulation techniques to see if we can get them to produce.”
Shell plans to use a water-based frack of 90 percent to 95 percent water, 4 percent to 9 percent sand and 1 percent guar gel, according to the article.
