Abstract:
Apparatus and methods for decreasing pressure of drilling fluid within a region between an impeller and a housing of a power generation module (PGM). The apparatus comprises a shaft extending from and rotatable relative to the housing; The impeller is coupled with the shaft external to the housing and includes a group of blades that rotate the impeller as the drilling fluid flows past the PGM. The impeller further includes another group of blades that decrease the pressure of the drilling fluid within the region between the impeller and the housing when the impeller is rotating.

Claim (Index 12):
A method, comprising:\n conveying a bottom-hole-assembly (BHA) within a wellbore extending into a subterranean formation, wherein the BHA comprises a power generation module (PGM) disposed within a drill collar of the BHA, and wherein the PGM comprises:\n a housing; \n a generator disposed within the housing; \n a shaft operatively connected with the generator and extending from the housing through a face seal; and \n an impeller coupled with the shaft and comprising a plurality of first blades that rotate the impeller as drilling fluid flows past the PGM; and \n pumping drilling fluid through the drill collar, thereby rotating the impeller, and thus the shaft, thereby causing the generator to generate electrical energy; wherein the impeller further comprises a plurality of second blades that decrease pressure of drilling fluid within a region between the impeller and the housing when the impeller is rotating.
