What is Impact of Hole Angle on Drilling Efficiency about?

Increasing hole angle generally makes cuttings transportation more difficult for drilling fluids. Drilling fluids must suspend weight materials and cuttings to prevent settling and reductions in density that could lead to kicks or blowouts. The drilling fluid must also transport cuttings out of the hole at a reasonable velocity to minimize incorporation into the fluid and ensure cuttings are released at the surface for efficient removal. Failure to adequately clean or suspend cuttings can cause problems lik
