Abstract
Methods, systems, and apparatuses for downhole sampling are presented. The sampling system includes a control unit and a housing to engage a conduit. The housing at least partially encloses at least one formation sampler to collect a formation sample. The formation sampler is stored in a sampler carousel. A sampler propulsion system forces the formation sampler into the formation. The propulsion system is in communication with the control unit.
