Summary
BSEE investigates pollution at Na Kika during an emulsion-breaker trial. Foaming disrupted separation and level readings, allowing oil discharge through the submerged produced-water outlet. Estimates put the release at approximately 89 barrels of oil and grease. Findings address inadequate training and delayed detection; reverting to the original chemical ended the sheening.
