Abstract
A method for reducing temperature of a bottomhole assembly during a drilling operation is disclosed, that, in one aspect, may include: drilling a borehole using a drillstring including a bottomhole assembly by circulating a fluid through the drillstring and an annulus between the drillstring and the borehole, pausing drilling, continuing circulating the fluid through the dill string and the annulus. The method further includes diverting a portion of the fluid from the drillstring into the annulus at a selected location above the drill bit to reduce temperature of the bottomhole assembly.
