ExxonMobil awards multi-zone stimulation technology license to Weatherford

ExxonMobil Upstream Research Company (URC) announced the licensing of its award-winning Multi-Zone Stimulation Technology (MZST) well treatment process to a subsidiary of Weatherford International Ltd. 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 will enable Weatherford to optimize its stimulation operations. The technology dramatically increases the number of zones that can be fractured per day compared to traditional fracturing and stimulation operations.
