Abstract: Methods and compositions utilize a sand obtained by combining a dirty sand with a chemical additive, where the combination decreases the water drain time through the sand compared to the sand without the chemical additive. The decrease of water drain time reduces the amount of time to dry the sand after a wash, and when using the sand for proppant, promotes conductivity of fluid through the sand when the sand is in a fracture of a subterranean formation.
