Abstract
Devices and methods for deploying perforating guns through a wellhead production assembly and into a wellbore. In particular embodiments, the invention provides devices and methods for deploying multiple perforating guns through a wellhead production assembly. In the event that the perforating gun assembly is dropped into the wellhead production assembly, a safety clamp will land upon a landing profile within a deployment riser, preventing the perforating gun assembly from falling into the wellbore.
