Dye Dispersion Studies
Numerical Modeling

Lorax Environmental has extensive expertise in the area of two and three-dimensional visualization of numerical model output as well as photo-realistic video production of actual and simulated environmental processes.

Numerical modelling and 3D visualizations are used in the oil and gas industry to simulate and view the dispersion of well cuttings and produced water from offshore drilling rigs. Well cuttings are particles of crushed rock produced by the grinding action of the drill as it penetrates the earth and produced water is created when seawater is used to force oil out of the reserves in underwater oil fields. These particles are released from near-surface discharge ports, either from a floating production and offshore loading system (FPSO) or from an ocean drilling platform.

Lorax Environmental Services employs sophisticated 3D hydrodynamic and plume dispersion models to simulate the distribution and loading of drill cuttings and the dispersion of produced water into the ambient waters. Realistic 3D animated underwater visualizations are used to demonstrate, qualitatively, the motion of drill cuttings and produced water plumes as they settle, disperse and advect with the prevailing currents.

Qauntitative 2D visualizations of wellcuttings and produced water are displayed using the SEAINFO model results viewer. SEAINFO is a computer application that is distributed to our clients in the Oil and Gas Industry who require the flexibility of viewing and querying model results in a fast and reliable way. In order to achieve compliance with federal and local quidelines on the discharge of waste matter from offshore drilling sites, clients use SEAINFO to display static or animated dilutions and concentrations mapped to colour coded scales. Violations of environmental standards are easily determined when limit criteria are prescribed in the SEAINFO model results viewer.
