This paper presents results from an experimental study of torque and cutting transport in two different wellbore geometries; one circular and one non-circular, where spiral grooves have been deliberately added to the wellbore wall in order to improve cuttings transport. Improving borehole hydraulic and mechanics will improve drilling efficiency in general, and will in particular enable longer reach for extended reach drilling (ERD) wells. The experiments have been conducted as part of an R&D project where the goal was to obtain reduced friction and improved borehole hydraulics and hole cleaning for more efficient drilling and well construction. The experiments have been performed under realistic conditions using a flow loop which includes a 12 meter long test section with a 2" OD freely rotating drillstri...

This paper presents results from experimental laboratory tests where hydraulics and hole cleaning have been investigated for two different wellbore geometries; circular and a noncircular, where spiral grooves have been deliberately added to the wellbore wall in order to improve cuttings transport. Improving hole cleaning will improve drilling efficiency in general, and will, in particular, enable longer reach for extended reach drilling (ERD) wells. The experiments have been conducted as part of a research project, where friction and hydraulics in noncircular wellbores for more efficient drilling and well construction are the aim. The experiments have been performed under realistic conditions. The flow loop includes a 12 m long test section with 2" diameter freely rotating drillstring inside a 4" diamet...
