Wireless Technology Optimizes Production in Mining Operation
Natural Soda operates seven production well pairs in Colorado to produce saturated nahcolite brine for manufacturing sodium bicarbonate (baking soda).
Mining nahcolite requires very careful monitoring of temperature, pressure and flow to not only optimize production performance—but also to mine the product sustainably and protect the freshwater aquifer.
