DYNAenergetic's No Debris Gun System (NDG)
How clean can you get? Perforating jobs traditionally leave a lot of unwanted debris in the well. The interior of the perforation guns and the cases of the shaped charges are fragmented during the shot. To overcome this situation DYNAenergetics GmbH & Co KG has developed a new type of perforating gun system. This patent pending No-Debris Gun System (NDG) leaves essentially no debris in the well. The basic idea behind this is to close the shot holes in the gun after the shot. This is achieved by an internal sliding sleeve.
Tests with the NDG made in accordance with the new API RP 19b Section V standard have proven that no debris can exit the gun during or after the shot. The NDG can be used with any standard shaped charge independent of size, geometry or explosive type. QC shots with shaped charges in a NDG setup have shown little or no penetration loss.
