A method for estimating the quantity of CO2 present in a geologic formation and a device for implementing the method include the steps of penetrating the formation by a well drilled from the surface contacting formation with a fluid that travels from the formation to the surface sampling a given quantity of return fluid at the surface and transferring it to a cell, ensuring the pH of the quantity of fluid, adding a given quantity of product acidifying the fluid to adjust the pH to a value of less than 4, and measuring the CO2 level of the gas in the cell after the acidification step.
