Abstract:
1. A method of disposing of produced water recovered during hydrocarbon production operations at one or more hydrocarbon well, the method comprising: conducting hydrocarbon drilling operations at at least one hydrocarbon well; collecting produced water that includes dissolved formation solids and is generated during the hydrocarbon production operations at the hydrocarbon well; mixing Type I Portland cement with the produced water to form a cementitious slurry; delivering the cementitious slurry to an underground void at another location for disposal therein; introducing the cementitious slurry into the underground void; allowing the cementitious slurry to set and produce cement having a compressive strength of at least approximately 400 psi within approximately 48 hours; and during setting of the cementitious slurry, preventing leaching of formation solids from the produced water beyond approximately four inches into the earth surrounding the underground void.
