Abstract
Apparatus and methods for launching objects into a wellbore. The apparatus generally includes a first object container and a container actuator. The first object container includes first compartments. The container actuator is adapted to displace the first object container so that respective ones of the first compartments are sequentially aligned with an opening. When the respective ones of the first compartments are sequentially aligned with the opening, objects loaded into the respective ones of the first compartments are sequentially launchable through the opening and into the wellbore. In some embodiments, the apparatus further includes a second object container including second compartments and being positionable above the first object container so that the respective second compartments are aligned with the respective first compartments. Objects loaded into respective ones of the second compartments are sequentially launchable through the respective ones of the first compartments, through the opening, and into the wellbore.
