Embodiments of the present invention generally relate to a method and/or apparatus for deploying wireline tools with a non-electric string. In one embodiment, a method of determining a free point of a tubular string stuck in a wellbore includes deploying a tool string in the stuck tubular with a non-electric string. The free point assembly includes a battery, a controller, and a free point tool. The method further includes activating the free point tool by the controller. The free point tool contacts an inner surface of the stuck tubular string. The method further includes applying a tensile force and/or torque to the stuck tubular string; and measuring a response of the tubular string with the free point tool.

1. A method of flow testing multiple zones in a wellbore, comprising acts of: lowering a tool string into the wellbore with a slickline, the tool string comprising a battery, a controller, an inflatable packer or plug, an electric pump, and a flow meter;operating the pump by the controller, thereby
1. A method of flow testing multiple zones in a wellbore, comprising acts of: lowering a tool string into the wellbore with a slickline, the tool string comprising a battery, a controller, an inflatable packer or plug, an electric pump, and a flow meter;operating the pump by the controller, thereby inflating the packer or plug and isolating a first zone from one or more other zones;monitoring flow from the first zone by measuring a flow rate using the flow meter;deflating the packer or plug;moving the tool string in the wellbore;operating the pump by the controller, thereby inflating the packer or plug and isolating a second zone from one or more other zones; andmonitoring flow from the second zone by measuring a flow rate using the flow meter, wherein the zones are monitored in one trip. 2. The method of claim 1, wherein: the tool string further comprises a second packer or plug, andeach zone is isolated by straddling using the packers or plugs. 3. The method of claim 1, further comprising: measuring a flow rate from a combination of the first zone, the second zone, and a third zone; andcalculating a flow rate of the third zone based on measurements of the first and second zones and the combined flow rate. 4. The method of claim 1, further comprising perforating a production zone on the same trip. 5. The method of claim 1, wherein the pump comprises: a pressure balanced closed working fluid system having a working fluid pump and an electric motor operable to drive the working fluid pump, anda 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. 6. A tool string for flow testing multiple zones in a wellbore, comprising: a slickline cable head;an inflatable packer or plug;an electric pump operable to inflate the packer or plug;a deflation tool operable to deflate the packer or plug in an open position, wherein: the deflation tool is repeatably operable between the open position and a closed position, andthe tool string is tubular;a battery;a flow meter;a memory unit operable to store data from the flow meter; anda controller operable to supply electricity from the battery to the pump. 7. The tool string of claim 6, further comprising a second inflatable packer or plug. 8. The tool string of claim 6, further comprising a perforation gun. 9. The tool string of claim 6, wherein the pump comprises: a pressure balanced closed working fluid system having a working fluid pump and an electric motor operable to drive the working fluid pump, anda reciprocating hydraulic pump having a drive piston for selective fluid communication with the working fluid pump and a pump piston for selective fluid communication with the wellbore and the packer or plug. 10. A method for setting a plug in a cased or lined wellbore, comprising acts of: deploying a tool string in the wellbore using a slickline, the tool string comprising: a battery;a controller;a setting tool coupled to the sickline, the setting tool having a first radial clearance between an outer surface of the setting tool and an inner surface of the wellbore casing;an adapter kit comprising an adapter sleeve, the adapter kit having a second radial clearance between an outer surface of the adapter sleeve and an inner surface of the wellbore casing, the first radial clearance being substantially greater than the second radial clearance; anda packer or plug comprising a packing element;actuating the setting tool by the controller, wherein the setting tool exerts a force on the adapter sleeve which transfers the force to the packer or plug, thereby expanding the packing element into engagement with an inner surface of the casing or liner; andseparating the setting tool from the packer or plug, wherein the adapter sleeve remains with the packer or plug. 11. The method of claim 10, wherein: the tool string further comprises one or more perforation guns, andthe method further comprises perforating the casing or liner at a first location, thereby forming one or more first perforations. 12. The method of claim 11, further comprising injecting formation treatment fluid into a formation via the first perforations. 13. The method of claim 12, further comprising removably and at least substantially sealing the first perforations. 14. The method of claim 13, wherein the first perforations are sealed using ball sealers. 15. The method of claim 13, further comprising perforating the casing or liner at a second location, thereby forming one or more second perforations. 16. The method of claim 15, wherein the first and second perforations are formed during the same trip. 17. The method of claim 15, further comprising injecting formation treatment fluid into the formation via the second perforations while the first perforations are sealed. 18. A tool string for use in a formation treatment operation, comprising: a slickline cable head;a setting tool comprising a mandrel, a setting sleeve, and a power charge operable to create high pressure gas for exerting a setting force on the setting sleeve,wherein: the setting sleeve is longitudinally moveable relative to the setting tool mandrel between a first position and a second position, and the setting tool has a maximum outer diameter;an adapter kit, comprising an adapter rod and an adapter sleeve, wherein: the adapter rod is longitudinally coupled to the setting tool mandrel and releasably coupled to a plug mandrel,the adapter sleeve is configured so that when the setting sleeve is moved toward the second position the setting sleeve abuts the adapter sleeve, andthe adapter sleeve has a maximum outer diameter substantially greater than the setting tool maximum outer diameter;a packer or plug comprising the plug mandrel and a packing element, wherein: the packing element is disposed along an outer surface of the plug mandrel,the adapter sleeve is configured to transfer the setting force to the plug, thereby radially expanding the packing element,the adapter sleeve is coupled between the packer or plug and the setting sleeve such that release of the adapter rod from the plug mandrel leaves the adapter sleeve with the packer or plug, andthe tool string is tubular,a battery; anda controller operable to supply electricity from the battery to the power charge for ignition thereof. 19. The tool string of claim 18, further comprising one or more perforation guns.
