Patent ID: 11946359

Abstract:
Methods and systems for identifying a fluid flow path in a subterranean development includes delivering a first cement slurry having a first slurry marker into an annular space, forming a first cement column at an elevation of a first reservoir layer. A second cement slurry with a second slurry marker is delivered into the annular space, forming a second cement column at an elevation of a second reservoir layer. The well casing, second cement column, and second reservoir layer is perforated and an initial fluids is produced. An initial amount of the first and second slurry markers initial fluids is measured. A packer is positioned across an inner bore of the well casing. The well casing, first cement column, and first reservoir layer is perforated and a subsequent fluids is produced. A subsequent amount of the first and second slurry markers in the subsequent fluids is measured.
