Titan Division of Hunting Energy Services, a subsidiary of Hunting PLC, the international energy services company, has introduced a new line of circulating shaped charges designed to improve cement placement during well plug and abandon (P&A) operations.
Building on the perforating technology of the company’s first generation of KnockOut circulation (puncher) shaped charges, the KnockOut 360° circulating shaped charge eliminates the earlier version’s requirement for a zero phased gun configuration which could limit the area open to flow and coverage required for a reliable cement plug.
The system can be run in a phased gun configuration to perforate 360 degrees of the inner tubing, leaving the outer casing with minimal controlled damage regardless of primary to secondary casing orientation. This makes it the ideal circulating shaped charge line for P&A applications.
It also provides consistent entry holes in the inner tubing to maximise open flow area, and perfect cement distribution for plugging the well. The system is currently available in 2 in. and 5-1/8 in. O.D.’s. A 7 in. version is in development for release later this year.
Hunting’s perforating technology is accessible through Hunting’s network of distribution centers strategically located in all the world’s oil-producing regions.
