摘要

The present disclosure relates to testing tools that comprises: a cable-head assembly for connecting the testing tool to an end of a length of coiled tubing; a pump assembly comprising a downhole pump; an upper packer-assembly comprising an upper packer-element; a lower packer-assembly comprising a lower packer-element; a sensor assembly comprising one or more sensors with the sensor assembly positioned in fluid communication with a plenum between the upper and lower packer assemblies; and a testing port that is adjacent the sensor assembly. The testing tool is moveable between a first configuration where the upper and lower packer-elements are unset and a second position where the upper and lower packer-elements are set and the testing port is in fluid communication with the downhole pump. Methods of using the testing tools is also described.
