Abstract
System and methods for delivering objects formed of a solid material into a circulation fluid of a subterranean well include a volume transfer container. The volume transfer container has an inlet port, an outlet port, and a charge access opening sized to provide for the filling of the volume transfer container with the objects. A discharge line extends from a pump assembly to the volume transfer container. A transfer line extends from the volume transfer container to the drilling assembly, providing a fluid flow path from the volume transfer container to the drilling assembly that is free of any pump.
