Comparison of flowmeter injection profile and DTS and DAS response during Inj2. Transparent lines are raw DTS data, sharp lines are moving average over 10 m. a Flowmeter profile with five DTS profiles in the first hour of cold water injection over from 2750 m MD to TD. b Zoomed to top of the reservoir. Flowmeter profile is shown together with three DTS profiles of injection start, each 20 min apart; and DAS strain at 1 min and 1.5 min after injection start
