For this test, standard API concrete targets were perforated with conventional and CoFrac® System measuring 4.25 in. OD and loaded 5 SPF. The 39-gram RDX shaped charge was the same for both tests. The concrete test targets were 17.1 ft. X 4.6 ft.
After detonation, the concrete target perforated with the conventional method indicated a few narrow fractures, but no obvious trace of surface breakage.
The target perforated with CoFrac® System had wide fractures and was very clearly broken, indicating that a secondary energy wave had entered the target.
When the shaped charge detonates, the perforation jet carries the proprietary ReCo® Propellant Cap into the reservoir zone, releasing energy directly to the perforation. This results in cleaner and deeper perforations that boost reservoir productivity.
