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 hydraulic pump portion having a reciprocating drive piston in selective fluid communication with the working fluid pump and longitudinally coupled to a pump piston in selective fluid communication with the wellbore and the packer or plug to drive pressurized filtered wellbore fluid to 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 (100b, 100c); measuring a flow rate from the one or more other zones (100b,100c); applying a tensile force through the wireline to pull a mandrel in a deflation tool while overcoming a biasing force to align flow ports in the mandrel with exterior ports to deflate 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 (100a,100b) from the remaining one or more other zones; and measuring a flow rate from the remaining one or more other zones, wherein the flow rates are measured in one trip. 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 hydraulic pump portion having a reciprocating drive piston in selective fluid communication with the working fluid pump and longitudinally coupled to a pump piston in selective fluid communication with the wellbore and the packer or plug to drive pressurized filtered wellbore fluid to the packer or plug; 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 hydraulic pump portion having a reciprocating drive piston in selective fluid communication with the working fluid pump and longitudinally coupled to a pump piston in selective fluid communication with the wellbore and the packer or plug to drive pressurized filtered wellbore fluid to 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 (100b, 100c); measuring a flow rate from the one or more other zones (100b,100c); applying a tensile force through the wireline to pull a mandrel in a deflation tool while overcoming a biasing force to align flow ports in the mandrel with exterior ports to deflate 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 (100a,100b) from the remaining one or more other zones; and measuring a flow rate from the remaining one or more other zones, wherein the flow rates are measured in one trip.
