EMDS corrosion log 1

EMDS corrosion log 1

Sequence of log: 1. One down/up shut in pass with speed 16.5m/min 2. Two injection down/up passes with speed 8m/min) across zone of interest. On the left side of the plot are: 2 curves which are recorded under shut in condition and 4 curves are recorded under injection condition. On the right side of the plot is the average velocity curve and the calculated velocity curve. Fluctuation levels on the average velocity curve does not exceed 30m/h that corresponds to the resolution of the injection rate of 10M3/d in 6”casing. Full Bore Spinner was run in this well but spinner was blocked so no data from Full Bore Spinner was recorded.

 

Plot presented in this slide shows a graph with the results of the quantitative USS data interpretation: that are the curves of relative volume and flow during injection and the injection profile. Calculated injection rate was 209M3/day. It also shows the density curve obtained by ultrasound channel, and the curve of mineralization, recorded by basic module K-5. These two curves are qualitatively similar to each other, but the detail of the density curve is much greater at the expense of high resolution.
