Weatherford has been awarded a license to market the Multi-Zone Stimulation Technology (MZST) well treatment process, developed by ExxonMobil Upstream Research Company. The MZST process can be used for hydraulic fracturing operations in tight gas, shale gas and CBM wells that target multiple reservoir zones, thick reservoir sections or long reservoir intervals, where multiple stimulation treatments are required. The MZST process allows stimulation in multiple payzones in a single operation, which enhances oil recovery and ultimately increases profitability. The process dramatically increases the number of pay zones fractured daily and reduces completion costs without compromising safety or well integrity—even from unconventional reservoirs with low permeability. There are two primary methods associated with the process—Just-in-Time Perforating (JITP) and Annular Coiled-Tubing Fracturing (ACT-Frac)—which deliver 40 or more zone-specific, customized treatments in a single well.
The JITP method can perform multi-zone stimulation in a single run in vertical, deviated and horizontal wells, using ball sealers for diversion between frac stages. The ACT-Frac method involves treatments being pumped at high flowrates down the annulus of coiled tubing to facilitate efficient, effective stimulation.
