Downhole flow monitoring and evaluation using distributed acoustic sensing and acoustic noise logging

A non-transitory computer-readable storage medium having embodied thereon instructions that when executed by one or more processors cause the one or more processors to:

• receive distributed acoustic sensing (DAS) data from a fiber optic cable deployed in a wellbore;
• identify a sound of interest at a wellbore depth based on an analysis of the DAS data received from the fiber optic cable;
• control deployment of a noise logging tool at the wellbore depth based on the analysis of the DAS data received from the fiber optic cable;
• receive acoustic data sensed by the noise logging tool at the wellbore depth;
• identify characteristics associated with the sound of interest based on an evaluation of the acoustic data collected by the noise logging tool, wherein the identified characteristics characterize the sound of interest as being indicative of a fluid flow downhole defect;
• and
• change a wellbore operation based on the identified characteristics by performing one or more remedial or control actions in the wellbore.

A system comprising:

• a fiber optic cable deployed in a wellbore, wherein the fiber optic cable is part of a distributed acoustic sensing (DAS) system;
• a noise logging tool;
• a memory;
• and
• one or more processors that execute instructions out of the memory to:
• receive DAS data from the fiber optic cable;
• identify a sound of interest at a wellbore depth based on an analysis of DAS data received from the fiber optic cable deployed in the wellbore;
• control deployment of the noise logging tool to the wellbore depth based on the analysis of the DAS data received from the fiber optic cable,
• receive acoustic data sensed by the noise logging tool at the wellbore depth;
• identify characteristics associated with the sound of interest based on an evaluation of the acoustic data collected by the noise logging tool, wherein the identified characteristics characterize the sound of interest as being indicative of a fluid flow downhole;
• and
• change a wellbore operation based on the identified characteristics by performing one or more remedial or control actions in the wellbore.

A method comprising:

• receiving DTS data from the fiber optic cable deployed in a wellbore;
• identifying a temperature of interest at a wellbore depth based on an analysis of the DTS data received from the fiber optic cable;
• deploying a noise logging tool at the wellbore depth based on the temperature of interest being identified at the wellbore depth;
• sensing acoustic data by the noise logging tool at the wellbore depth;
• identifying characteristics associated with the sensed acoustic data based on an evaluation of the acoustic data collected by the noise logging tool, wherein the identified characteristics characterize the sensed acoustic data as being indicative of a fluid flow downhole;
• and
• changing a wellbore operation based on the identified characteristics by performing one or more remedial or control actions in the wellbore.
