Apparatus and method for testing an oil and/or gas well with a multiple-stage completion
First Claim
1. A testing tool for testing individual stages of a well, the testing tool comprising:
- an uphole end and a downhole end, the uphole end is operatively connectible to a coiled tubing string;
a downhole pump,an upper packer-assembly and a lower packer-assembly;
a sensor assembly comprising one or more sensors, the sensor assembly is in fluid communication with a position between the two the packer assemblies and the downhole pump; and
a flow-through conduit for receiving fluids from the coiled tubing string and for conducting said fluid between the uphole end and the downhole end.

Abstract
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.

11. A method comprising steps of:
-
a. connecting a testing tool to one end of coiled tubing; b. running the coiled tubing and the testing tool into a well; c. circulating fluids through the coiled tubing and out of a downhole end of the testing tool; d. positioning the testing tool substantially adjacent a first perforated section of the well; e. setting a first packer element on one side of the first perforated section of the well and a second packer element on an opposite side of the desired perforated section; f. establishing fluid communication between a sensor assembly of the testing tool and the first perforated section; g. pumping fluid through a downhole pump of the testing tool at a first output parameter; h. capturing fluid-property data and/or pressure data from test fluids as they are pumped towards the downhole pump; and i. unsetting the packer elements. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
