1. A reverse flow gas separator for separating gas from liquid in a wellbore comprising:
a housing having a housing intake; wherein there is a first void space within the housing; and
a driveshaft disposed adjacent to the first void space; wherein the drive shaft is hollow and comprises a second void space disposed within the interior of the drive shaft; wherein the second void space is continuous from a driveshaft intake to an opening in a terminal end of the driveshaft; wherein the driveshaft further comprises an auger disposed within the second void space; wherein the housing intake and driveshaft intake are positioned relative to each other such that a fluid entering the housing intake reverses flow relative to the flow of the fluid from outside the reverse flow gas separator in order for the fluid to enter the driveshaft intake.
