titleOfInvention | Process-based approach for the detection of CO2 injectate leakage |
abstract | The present invention includes a method for distinguishing between a natural source of deep gas and gas leaking from a CO 2 storage reservoir at a near surface formation comprising: obtaining one or more surface or near surface geological samples; measuring a CO 2 , an O 2 , a CH 4 , and an N 2 level from the surface or near surface geological sample; determining the water vapor content at or above the surface or near surface geological samples; normalizing the gas mixture of the CO 2 , the O 2 , the CH 4 , the N 2 and the water vapor content to 100% by volume or 1 atmospheric total pressure; determining: a ratio of CO 2 versus N 2 ; and a ratio of CO 2 to N 2 , wherein if the ratio is greater than that produced by a natural source of deep gas CO 2 or deep gas methane oxidizing to CO 2 , the ratio is indicative of gas leaking from a CO 2 storage reservoir. |
