The injection well may have an open interval permitting fluid communication f into the mafic and/or ultramafic rock. A cured cement may be present between the mafic and/or ultramafic rock and the injection casing and may be formed from a cementitious slurry mixture containing a class G cement, fly ash, microsilica, additives, and an epoxy resin blend. An injection tubing is disposed in the interior of the injection casing, having fluid communication with the interior of the injection casing. A packer connected to the injection tubing may be present as a fluid seal within the injection casing.[French]
