A gas well completed in a reservoir at $5600$ psia and $225\backslash$deg F is producing $10$ MMscfd of $0\mathrm{.}710$ specific gravity gas and $8$ barrels of water per day Surface conditions are $700$ psia and $75\backslash$deg F$.$ Flow much of the produced water is condensed from the gas and fow much is formation water? The reservoir water is a $62000$ ppm brine. Estimate the resistivity of the formation water.
