| Abstract | We have analyzed chemical monitoring data fiom three production wells at Sumikawa to assess the fraction of reinjected water in the produced fluid. Fractions are estimated sequentially with an on-line analysis method applied to a lumped parameter reservoir model. Production fluids from each well receive different magnitudes of reinjection returns. Appreciable changes in estimated fractions occur with time at production Well SC-1. |
