Fully Dissolvable Plug-and-Perforation System

Schlumberger introduced the Infinity dissolvable plug-and-perforation system. This unique solution uses fully degradable fracture balls and fully degradable seats instead of plugs to isolate zones during well stimulation. With the Infinity system, the ball and the seat assemblies both fully dissolve on contact with common completion fluids. As a result, the well is left with full-bore access, enabling customers to bring production online faster, more efficiently, and more cost-effectively. The first-ever full-bore interventionless plug-and-perforation system eliminates the need for milling operations and leaves nothing behind in the wellbore. As a result, no plug debris is produced to surface where it can potentially interfere with surface equipment. The technique eliminates lateral-length restrictions, which maximizes reservoir contact and estimated ultimate recovery, and it greatly reduces intervention-related risks and costs. A customer in south Texas deployed the Infinity system in a seven-well project that began with partial wellbores and, after early success, moved on to full-wellbore completions. The system was deployed under extreme conditions, with temperatures up to 320°F in laterals up to 8,000 ft. In these wells, more than 135 stages were completed with no stages skipped and no type of mechanical intervention required.
