TejanoBrown on the Ground TB-2
Inside a Perf Gun
On Episode 2 of On the Ground with Tejanobrown, we get to see the insides of a perf gun. Our host Tejanobrown shows how the charge carrier works, highlighting the jet perforating charges, the through wire and primer cord, and the detonator. Once the gun is in place downhole, an electrical current is sent down the through wire to set off the explosive fuse to start the primer cord at about 60 pounds of pressure. The primer cord passes through each jet perforating charge causing the explosions to punch through casing, cement, and into the target formation.
