Produced water discharge is tightly regulated and monitored. The applicable standard, its averaging basis and the reference analytical method together define the engineering target for the treatment train.
Deoiling, softening and polishing of produced water for discharge, reuse or reinjection.
Flotation for removal of dispersed oil and fine solids from oilfield water.
Primary gravity and plate separation of free oil and solids ahead of polishing.
The OSPAR convention sets a 30 mg/L monthly-average dispersed-oil performance standard for offshore discharge in the North-East Atlantic.
US effluent limitations guidelines for oil and gas extraction set daily-maximum and monthly-average oil-and-grease limits by region.
National and onshore regimes impose their own limits on oil, salinity, toxicity and specific pollutants.
The defined analytical method (for example infrared or GC-based) fixes how oil-in-water is measured against the limit.
Online oil-in-water analysers give continuous performance visibility and early warning of excursions.
Representative sampling and record-keeping evidence sustained compliance to the regulator.
The treatment train is sized to the standard, its averaging basis and a margin for variability.
Duty/standby and buffering protect compliance through upsets and maintenance.
Commissioning and ongoing monitoring evidence that the plant meets its consent.
