Abstract
The present application discloses systems and methods for utilizing drilling byproducts from gas and oil wells to make commercially-marketable concrete. According to one inventive concept, the byproducts (which includes drill cuttings and flow-back) are treated with a dewatering agent to form a waste slurry, and the waste slurry is then added to a concrete-mixing process as the final component, after all of the other components of the concrete-mixing process have already been blended together. In some embodiments, the dewatering agent is calcium oxide (CaO). According to another inventive concept, the drilling byproducts that are collected from a first drilling site may be used to form the concrete that is to form a concrete drilling pad that is located at a second drilling site.
