Abstract
A method for detecting wellbore inflows can include detecting a plurality of temperature values within a wellbore, wherein each temperature value corresponds to a different depth within the wellbore and the temperature values are detected with a distributed temperature measuring technique. The method can also include calculating a plurality of proxy temperatures, wherein each proxy temperature corresponds to one of the temperature values and a reference temperature value. The method can also include calculating a continuous wavelet transform based on the plurality of proxy temperatures. Additionally, the method can include identifying a wellbore inflow based on a combination of the continuous wavelet transform and a wellbore schematic, and generating an alert indicating a location of the wellbore inflow within the wellbore.
