Dye Dispersion Studies
Numerical Modeling

Produced water originates on offshore oil production platforms when water that has been injected into a well is recovered and treated to remove contaminants. It is then discharged back into the ocean below the surface at an elevated temperature, and may contain trace amounts of hydrocarbons and other contaminants as well as dissolved air.

The initial behaviour of the produced water plume is complex and not well understood in some cases. For instance, in one case it is known that a portion of the produced water rises up to the surface, while some descends to depths of 80 m or more.

In 2005 Lorax designed and conducted the first field program in the North Atlantic designed specifically to measure the far-field dilution of produced water. Fluorescent rhodamine dye was added to the Produced Water stream onboard the FPSO oil production vessel at Terra Nova. Data collected during this two day study were subsequently used to verify the Lorax Produced Water Dispersion Model.
