CoFrac™ Gun has achieved the directional control of energy. When the detonator is fired, the shaped charge discharges to create an explosion jet and conducts perforation. The perforation jet carries the propellants into the perforating tunnel. Pressure drop triggers the propellants to burn continuously throughout the tunnel, releasing energy directly to the perforation tunnel.
Plug-N-Play with regular shaped charges; Increase perforation entrance hole diameter (EHD); Deepen perforation penetration; Eliminate perforation tunnel crushed zone; Induce fractures (pre-fracturing) to formation
Lower fracturing formation breakdown pressure; Reduce or eliminate the possibility of fracturing screen-out (better sand placement)
Additional enhanced production; Prolong enhanced production; Reduce operating costs by improving the effectiveness and efficiency of perforating and fracturing; Improve the operational HS&E
ARECO’s CoFrac™ system molds a high energy propellant cap at the front-end of any regular shaped charge. After the shaped charge jet perforates the formation, the propellant material is pushed into the perforation tunnel where it deflagrates continuously. The energy released by the deflagration will apply directly to the perforation tunnel, creating a fracture network without damage to the wellbore and casing. The working mechanism, the pressure transfer between the wellbore and formation, and location of propellant deflagration is ultimately different from that of other perforation methods.
With the help of the CoFrac™ Gun system, perforation operations become highly efficient. CoFrac™ perforating creates fracture networks around the perforating hole, which is the most desirable working condition for subsequent hydraulic fracturing operations. The data from thousands of well perforating operations have shown that fracturing pressure was reduced between 10 and 30% by using the CoFrac™ perforation gun. The consumption of hydraulic fracturing proppants increased between 15% and 30%. This dramatically reduces the difficulty and cost of fracturing operations.
ARECO technology will greatly improve productivity for conventional and unconventional reservoirs while reducing the cost of fracturing and acidizing operations. Our technology is compatible with equipment used by traditional completion methods. There is no need for additional equipment, personnel or tools.
