Angled drill pipe nozzle assemblies

A method of drilling a borehole, comprising:

• extending a drill string into the borehole from a drilling platform, the drill string having a drill bit arranged at a distal end thereof and a plurality of nozzle assemblies are installed on the drill string, each nozzle assembly operable to provide a fluid flow path between an interior of the drill string and an annulus defined between the drill string and an inner wall of the borehole;
• conveying a drilling fluid into the drill string and to the drill bit;
• discharging a spent drilling fluid from the drill bit and into the annulus;
• transitioning at least one of the plurality of nozzle assemblies from a closed state, in which the drilling fluid within the interior is prevented from passing through the fluid flow path, to an open state, in which the drilling fluid traverses the fluid flow path and is discharged into the annulus;
• and
• combining the drilling fluid discharged into the annulus with the spent drilling fluid and thereby aiding the spent drilling fluid in carrying drill cuttings uphole within the annulus.
