Abstract (en)

[origin: EP2772610A1] A method for determining the profile of fluids inflowing into multi-zone reservoirs provides for temperature measurement in a wellbore during the return of the wellbore to thermal equilibrium after drilling and determining temperature of the fluids inflowing into the wellbore from each pay zone after perforation at an initial stage of production. Specific flow rate for each pay zone is determined by rate of change of the measured temperatures.
