Enabling Subsea Produced Water Reinjection through In-line Water Treating and Monitoring Technologies for Deep Water Applications
two microscopy-based produced water quality monitoring sensor prototypes were developed and tested in a flow loop over a broad range of operating conditions. the low measurement range sensor is intended to be installed downstream of the water treatment system to measure the quality of reinjection water, and the high measurement range sensor is to be installed upstream of the water treatment system to serve primarily as a trend monitor. the test results indicated that both sensors can measure oiw with sufficient accuracy for monitoring produced water in subsea applications.
