What was once not a commercial source of natural gas, today’s hydraulic fracturing technologies have improved the viability of producing shale plays. However shale plays still present numerous challenges including geological uncertainty, horizontal, high-angle wells, low permeability, and an increased cost and risk associated with recovery.
Proper zonal isolation is imperative in effective completion design. Weatherford’s swellable packers enable interventionless diversion of the fracturing treatment and offers life-of-well zonal isolation, while minimizing the time and cost to complete multiple reservoir sections.
