Characterisation of Offshore Drill-Cuttings for Simulation Purposes

摘要

Several models exist to predict the dispersion of drill-cuttings from offshore installations in the North-Sea. The sensitivity of one of these models to oceanographic data and drill-cuttings characteristics has been tested. Questions about the relevance of the required input data have arisen. A better knowledge of drill-cuttings characteristics would result in more accuracy and appropriateness of the input data and therefore of the output data. Some correlations between drilling procedures and drill-cuttings characteristics can be obtained from historical data, surveys on new wells and laboratory experiments.
