Publication number: 20200190932Abstract: A drone conveyance system for deploying drones into an oil or gas wellbore is described. The system includes a platform, a drone magazine, a platform receiver, a conveyance, and a wellhead receiver. A drone magazine contains a plurality of the drones and selectively releases/feeds the drones into the platform receiver. More than one drone magazine, each containing different drone types, may supply drones to the platform receiver such that different drones may be ordered for disposal into the wellbore. The platform receiver prepared the drones to be moved from the platform to the wellhead by the conveyance. The wellhead receiver accepts the drones from the conveyance and prepares each received drone for dropping into the wellbore via the wellhead.Type: ApplicationFiled: February 11, 2020Publication date: June 18, 2020Applicant: DynaEnergetics Europe GmbHInventor: Christian Eitschberger
