Of all the technologies that have propelled the unconventional boom in the United States over the past 15 years, plug and perf (P&P) remains the number one method for stimulating multistage wells, enabling operators to achieve significant economic gains in previously inaccessible reservoirs.
The Infinity dissolvable plug-and-perf system operates in the same fashion as a conventional P&P, but uses fully dissolving seats, instead of plugs, for isolation. The system was designed for use in cemented, uncemented, vertical, deviated, and horizontal wells in shale, sandstone, carbonate, and other rock types. The seat assemblies serve the purpose of plugs and dissolve in a controlled manner after the stimulation has been performed, leaving a full-bore inner diameter.
The dissolvable P&P system has been deployed in most of the major unconventional plays in North America. During the early stages of the system validation, Schlumberger collaborated with several operators in the Eagle Ford Shale in Texas. Because this play presents high-pressure/high-temperature challenges at bottomhole conditions, it was well suited for testing the limits of the technology.
