The MZST process can be used to rapidly and reliably stimulate multiple zones in a single operation, yielding improved well economics.
The MZST process can be particularly beneficial for hydraulic fracturing operations in tight gas, shale gas and coal bed methane wells that target multiple reservoir zones, thick reservoir sections or long reservoir intervals where multiple stimulation treatments are required.
'The MZST process is a proven technology for rapidly completing wells in tight reservoirs such as shale gas,' said URC President Sara Ortwein. 'As shale gas takes on growing significance, this technology will play a key role in improving the economics of developing this unconventional resource.'
The MZST process will enable Weatherford to optimize its stimulation operations by combining the deployment of perforating and hydraulic fracturing equipment simultaneously in the wellbore to enable "single-trip" multi-zone stimulations. The technology dramatically increases the number of zones that can be fractured per day compared to traditional fracturing and stimulation operations.
'We are always looking for proven technology to reduce completion costs without sacrificing safety or well integrity,' said Gary Flock, Weatherford vice president of pressure pumping. 'The MZST process is an excellent fit with our existing portfolio of completion and well stimulation technologies and services and will help us add value to our customers in the unconventional gas business.'
The MZST process was developed by ExxonMobil Upstream Research Company, an affiliate of Exxon Mobil Corporation. The technology was recognized with Platts Global Energy Award for Most Innovative Commercial Technology in 2005 and has been licensed to numerous service companies.
