Speaking of oilfield services (OFS) companies that are the result of mergers and acquisitions, for a number of years MDN tracked the monthly rig count for Patterson-UTI Energy as a proxy for rig count health in general and rig count health in the Marcellus/Utica in particular. Patterson operates many rigs in the M-U region. In April 2017, Patterson bought out and merged in Seventy Seven Energy, which was the spun-off former Chesapeake Oilfield Operating company (see Patterson-UTI Energy Completes Merger with Seventy Seven Energy). Because of a slow-down in drilling, Patterson is now looking to sell off its pressure pumping (i.e. fracking) business.
