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.

Wellbore inflow detection based on distributed temperature sensing

Herein disclosed are methods and systems related to processes for injection wells generally utilized in the oil and gas industry. More particularly, disclosed herein are methods and systems related to improving the accuracy of profiling and determining individual cumulative fluid injection profiles for an injection period for multiple zones of an injection well in reservoir systems utilizing conventional warmback models. The methods herein allow for proper modeling and allocation of all injection zones, including zones experiencing a cooldown phenomena during shut-in by transforming the cooldown zonal temperature profiles into temperature profiles which can be utilized in a conventional warmback analysis. These methods are particularly useful in mature reservoir systems where the background reference temperature profile is no longer governed by the geothermal reference temperature profile.

A method and system are described for communicating within a system, which may be along tubular members. The method includes constructing a communication network for a hydrocarbon system, which includes one or more wellbores accessing a subsurface region or a pipeline, and using the communication network in hydrocarbon operations, such as hydrocarbon exploration, hydrocarbon development, and/or hydrocarbon production.
