Fracture gun TCP Operation
Fracture perforating gun oilfield production
Frac gun combines perforating and high energy gas fracturing in one run. This technology is designed by combining
two kinds of energy from explosive detonating and propellant burning. After initiated, perforating charges are
functioned in microseconds to produce perforating channels; the propellant is burned and outputs high temperature
and high pressure pulse gas in a speed in milliseconds to impact perforating channels for fracturing.
