WebJan 19, 2016 · Water production. The present worldwide daily water production from oil wells averages roughly 3 BWPD per barrel of oil, although some wells produce significantly higher amounts. It costs money to lift water and then dispose of it. In a well producing oil with 80% water cut, the cost of handling water can double normal lifting costs. WebCumulative water production: Equation (9.3.1) is considered a general material balance equation because it can be applied to an oil reservoir with a gas cap and an aquifer. The derivation of the material balance equation is based on several assumptions: the system is in pressure equilibrium; the system is isothermal; available fluid property ...
