Abstract
A well tool () includes a perforating gun (), a sealing element (), at least one pressure sensor (), a detector (), a controller (), and an anchor (). The perforating gun () perforates the wellbore tubular in response to a firing signal. The sealing element () is connected to the perforating gun () and generates a pressure differential thereacross. The at least one pressure sensor () is associated with the sealing element () and detects a surface transmitted pressure signal. The detector () detects at least one marker () positioned along the wellbore () and which includes a perforating marker () associated with a perforating depth. The controller () is in signal communication with the at least one pressure sensor () and the detector () and is configured to transmit the firing signal to the perforating gun () only after: (i) the at least one pressure sensor () detects the surface transmitted pressure signal, and (ii) the detector () detects the perforating marker (). The anchor () is connected to the perforating gun () and selectively locks the perforating gun () to the wellbore tubular.
