Abstract
A wireline interface sub includes a wireline-interface-sub housing mechanically coupleable to a wireline and a wireline-interface module electrically coupleable to the wireline. A first tandem sub includes a first-tandem-sub housing mechanically coupled to the wireline-interface-sub housing, a first-tandem-sub-upside transceiver wirelessly coupled to the wireline-interface module, and a first-tandem-sub-downside transceiver electrically coupled to the first-tandem-sub-upside transceiver. A first gun sub includes a first-gun-sub housing mechanically coupled to the first-tandem-sub housing, a first-gun-sub transceiver wirelessly coupled to the first-tandem-sub-downside transceiver, and a first-gun-sub detonator coupled to, and triggerable by, the first-gun-sub transceiver.
