Description:
A model for the calculation of the spreading and deposition of drilling mud and cuttings has been developed. The calculations are based on a Lagrangian particle approach, which means that the properties of the discharge are represented by moving particles in the model domain. The initialization of the particles is based on the output from an Eulerian near-field underwater plume model. In addition, the model applies external current fields for the horizontal advection of the particles. The paper explains details in a comparison made between measured barium concentrations in the sediment and the modeled deposition on the sea floor from the drilling of eight exploration wells and eight production wells for the development of an oil field in the North Sea.
