Yet another Range Resources alumnus is now working for someone else–himself. Matt Curry, a chemical engineer and Pittsburgh native who used to work for Range, along with Chris Combs, who’s worked for a number of drilling services companies in Texas, co-founded Praetorian Energy Solutions, a “pressure pumping and pumpdown services” headquartered in Canonsburg, PA. The company, launched earlier this year, is (so far) working in the Eagle Ford Shale play in Texas–because that’s where they bought their equipment. That equipment will be heading north soon to operate in the Marcellus/Utica. What is a pressure pumping/pumpdown company?
