SolutionGas Drive : Water cut

Commonly the water cut remains small in solution gas drive reservoirs, assuming that there is little pressure support provided by the underlying aquifer. Water cut is also referred to as BS&W(Base, Sediment & water) and is defined as:

      Water cut (BS&W) = (water production / oil plus water production) * 100(%)


$$ BS\&W = \frac{water \;production}{oil\;plus\;water\;production } * 100(\%) $$


  • $BS\&W$ is the water cut
