Abstract:
1. A method of optimizing well production, comprising: selecting a first interval along a horizontal part of a wellbore; isolating the first interval with an isolation mechanism of a test string deployed into the horizontal part of the wellbore; performing a test to obtain data on the first interval; processing the data on a control system in real time; implementing a first action to enhance production at the first interval based on results from processing the data, wherein implementing the first action is performed without removing any part of the test string from the wellbore, wherein implementing the first action comprises removing damage and improving permeability of the first interval; the control system using data collected by a sensor to evaluate results from performing the first action; when the results indicate that further action is to be taken for the first interval, implementing a second action to enhance production at the first interval; the control system using data collected by the sensor to evaluate results from performing the second action; and when the results from performing the second action indicate that no further action is to be taken for the first interval, releasing the isolation mechanism and moving the test string to a second interval to perform testing and treatment of the second interval, wherein implementing the first action and the second action with respect to the first interval comprises injecting treating fluids to the first interval through a concentric tubing section of the test string, wherein the treating fluids are injected through an inner flow channel of the concentric tubing section to the first interval; producing fluids from the first interval through an outer flow channel of the concentric tubing section to an annular region defined between the concentric tubing section and a production tubing placed inside casing lining the wellbore, wherein the outer flow channel is concentrically arranged around the inner flow channel.
