Hard water forms scale in boilers, water heaters, and ... R wa comparison. If water saturation is assumed to be 100%, the Archie water saturation equation (Eq. 1) reduces to .....(9) The term R wa is used in Eq. 9 rather than R w to indicate that this is an apparent formation water resistivity. It is only equal to R w in 100% water-bearing formations. In hydrocarbon-bearing formations, R wa computed …When a water-bearing rock readily transmits water to wells and springs, it is called an aquifer. Wells can be drilled into the aquifers and water can be pumped out. Precipitation eventually adds water ( …The taste of the water often is affected by the amount of dissolved solids.
