Flow-rate estimation constitutes one of the most important tasks in a closed-chamber test (CCT). During a CCT flow period, the reservoir fluids are allowed to accumulate in the drill-string, and are not produced to the surface. This operational aspect differentiates the CCT from a conventional drillstem test (DST), where the flow-rate is measured at the surface unless the well kills itself.
