Tyler formation tested with horizontal fracking
Marathon Oil is the first oil company to try modern horizontal fracking within the Tyler formation. They currently are approved to drill four wells in the Tyler formation, and the company has had an interest in the area for approximately three years. Several other companies, including Continental Resources and Whiting Oil and Gas, have also recently begun core testing in the area. The Tyler formation has been producing oil since the 1950s.
