This invention relates to a method and a system of abating carbon dioxide (CO) and/or hydrogen sulfide (HS) in a geological reservoir. Water is pumped or transferred from a water source to an injection well. The gasses are merged with the water under conditions where the hydraulic pressure of the water is less than the pressure of COand/or HS gas at the merging point. The water with COand/or HS gas bubbles is transferred further downwardly at a certain velocity higher than the upward flow velocity of said COand/or HS gas bubbles ensuring downward movement of gas bubbles resulting in full dissolution of said COand/or HS in the water due to elevating pressure. The complete dissolution ensures a lowered pH of the water entering a geological (e.g. geothermal) reservoir which is needed to promote mineral reactions leading to COand HS abatement This abatement may be quantified by dissolving a tracer substance in a predetermined molar ratio to said dissolved COand/or HS and monitored in a monitoring well.
