Comparison of DTS warm-back profiles and flowmeter injection profile with interpreted injection zones from flowmeter interpretation. Transparent lines are raw DTS data, sharp lines are moving average over 10 m. a Six DTS profiles taken at different times during the first 11 h together with flowmeter inflow profile. A, B, C and D mark gradient change of DTS profiles. b Zoom to the top reservoir section
