An oxygen activation log was modified for use in obtaining injection profile sun'eys in four short radius horizontal injection wells. The tool was run inside a workstring that was temporarily placed in the lateral. Injection was established down the well annulus and the tool measured flow rates at points in the annulus between the workstring and open hole lateral. From this data, a distribution of injection along the lateral could be determined. Three different stimulation techniques were used on the horizontal wells and the profile results provided valuable insight into the effectiveness of these techniques.
