Dynamic Under Balance
Perforating using Dynamic Underbalance technique allows us to generate tunnels without damages. This translates into higher well’s productivity.
Tunnels without damage
Perforating UnderBalance system is used when a balance o the well below the borehole is desired after detonation of the drill guns without displacing the well fluids.
The explosive pressure created by the detonation of the guns cuts two pins and releases a piston that opens an empty gun called a ported gun. This allows the fluids from the well to rush to the empty carriers connected below the fired gun, creating a low-balance situation in the well that helps cleaning the perforated channels. The number of empty carriers required is determined by the well and operator requirements.
