Abstract
Embodiments of the invention include methods and systems for perforating a well using a wired work string assembly. According to embodiments of the invention, the method includes positioning a wired 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. A depth of the perforating gun assembly is determined from a depth correlation tool positioned within the wellbore, and an electrical signal related to the depth of the perforating gun assembly is transmitted to a surface above the wellbore. Firing of the perforating gun assembly is initiated via a signal transmitted from the surface above the wellbore. An electrical signal from the wellbore is transmitted to the surface to confirming the firing of perforating gun assembly. The system includes various tools for perforating the well using the disclosed methods.
