Patent ID: 10613053

Abstract:
An automated method and system for identifying one or more chemical tracers present in a sample drawn downstream from the well head from a produced hydrocarbon oil/water stream in a pipeline from a downhole well completion, the one or more chemical tracers having originally been applied to the outer surface of one or more lengths of tubing placed at known locations in the assembly of the downhole well completion, the chemical identification of each of the tracers and the location of each of the tracers having been retrievably recorded for the well completion in the form of a relational database, by in situ testing of a portion of the aqueous layer of the sample following settling by means of an electrophoresis analysis system that includes a micro-fluidic chip and an electronic data information collection unit and signal communication means for transmitting conditioned data from the electronic data information collection unit to the central control station for comparison with, and identification of data associated with the chemical tracers and the location of the chemical tracers in the well completion from the relational database, and a user display device for displaying the results of the data comparison and identification so that appropriate remedial action to reduce the volume of produced water in the hydrocarbon stream can be taken.
