Abstract:
A borehole tool, having a cylindrical body, the cylindrical body having an upper shank, a lower shank, and a component tool disposed between the upper shank and the lower shank, wherein the tool is configured to have an outer surface airfoil configuration, whereby lift is created as fluid passes along the cylindrical body. The component tool can be a combination stabilizer tool, a reamer tool and a cutting removal tool, wherein the stabilizer tool is configured as a helical stabilizing blade and reamer blade, a flow path disposed between the helices of the stabilizing and reamer blade, the stabilizing and reamer blade further comprising a reamer cutting element disposed where an edge of the stabilizing and reamer blade meets the flow path.
