Pump system for zonal isolation testing

Abstract

A pump system for testing an isolated zone in a borehole includes a testing pump and a testing device. The testing pump may be configured to at least assist in creating a formation fluid flow from the isolated zone in the borehole. The testing pump may be powered by a power fluid, where the power fluid may be delivered from a power fluid source. The power fluid source may be located at a location remote from the testing pump. The testing device may be configured to monitor the formation fluid flow. The testing device may further be configured to determine characteristics of the isolated zone in the borehole based at least in part on the monitored formation fluid flow.
