Radioactive tracer flow logs run to determine the injection profile of a polymer fluid in an injection well erroneously indicated that almost all of the fluid was entering the upper one foot of the zone. To study this problem in greater detail, a 12-ft visible flow loop 6-in. and 8-in. in diameter, clear plexiglass tubing was built. Polymer solutions of 800 to 1200 ppM polyacrylamide and xanthan gum were evaluated at flow rates of 35 to 350 bpd using dye coloring shot from single-port and multiport injection logging instruments. Results of these flow tests showed that little mixing occurred between the injected dye and the flowing polymer solution. Conventional firing times generally caused almost all of the dye solution to stick to the wall opposite the firing port. Viscosity effects were correlated with ability to measure meaningful polymer injection profiles from the maximum velocities from radioactive tracer logs. A critical annular flow velocity of injected polymer was necessary in these tests to achieve maximum theoretic polymer flow velocities. Logging success was dependent on controlled firing time to provide maximum radioactive tracer placement in the flow regime.
