When an oil well is being drilled, rock cuttings are transported up to the surface by a flow of viscous non- Newtonian fluid. Current mathematical models of the flow and transport neglect the effects of drillstring rotation. Schlumberger wish to have a model that includes these effects. The Study Group identified many of the ingredients that need to go into building such a model.
