  • Patent number: 11434713
    Abstract: A drone conveyance system and a wellhead receiver for deploying drones into an oil or gas wellbore includes a platform, a drone magazine, a platform receiver, a conveyance, and a wellhead receiver. The wellhead receiver prepares the drone to be inserted into the wellbore via the wellhead. Preparation of the drone to be inserted into the wellbore includes adjusting the physical conditions surrounding the drone to approximate the physical conditions in the wellbore. The preparation may be performed using fluid inputs and outputs connected to a compartment of the wellhead receiver. Other preparation processes may also take place in the wellhead receiver such as assuring the appropriate drone is being inserted, that the drone has been programmed appropriately, that safety devices have been deactivated and charging an onboard power supply of the drone.
