Patent ID: 8672031

Claim:
A method for perforating a wellbore casing, comprising: positioning a work string assembly in a wellbore, the work string assembly comprising a plurality of wired pipe communicatively coupled at each joint, a depth correlation tool, and a perforating gun assembly; determining the depth of the perforating gun assembly via the depth correlation tool; transmitting a first electrical signal along the work string assembly from the depth correlation tool to a surface above the wellbore, the first electrical signal related to the depth of the perforating gun assembly; transmitting a second electrical signal along the work string assembly from the surface above the wellbore to the perforating gun assembly, the second electrical signal initiating firing of the perforating gun assembly; and transmitting a third electrical signal along the work string assembly to the surface above the wellbore, the third electrical signal related to a confirmation of the firing of the perforating gun assembly, wherein determining the depth comprises receiving depth data at the surface above the wellbore from the depth correlation tool via the work string assembly in real time or post-real time while the depth correlation tool is downhole.
