Patent ID: 8286703

Claim:
A method of flow testing multiple zones in a wellbore, comprising: lowering a tool string into the wellbore on a wireline, the tool string being coupled to the wireline and comprising an inflatable packer or plug and an electro-hydraulic pump, the pump comprising: a pressure balanced closed working fluid system having a working fluid pump and an electric motor operable to drive the working fluid pump, and a reciprocating hydraulic pump having a drive piston in selective fluid communication with the working fluid pump and a pump piston in selective fluid communication with the wellbore and the packer or plug; operating the pump using the wireline, thereby inflating the packer or plug and isolating a first zone from one or more other zones; measuring a flow rate from the first zone; deflating the packer or plug; moving the tool string in the wellbore; operating the pump using the wireline, thereby inflating the packer or plug and isolating a second zone from one or more other zones; and measuring a flow rate from the second zone, wherein the flow rates are measured in one trip.
