Leakage source parameters identification for CO₂ sequestration based on Occam method

CO₂ gases stored underground may escape from the reservoir site to other places and even through the soil layer into atmosphere, thus identify the leakage source is therefore a crucial problem after leakage occurring. The paper introduced a direct method to solve the inverse problem combined with the optimization method, which is Occam regularization method. This method was applied to estimate the source parameters. Firstly, the calculation process of Occam regularization method was introduced and then the feasibility of its application for source parameters identification was proved by simulation and experiment data. The results showed that, Occam regularization method is able to estimate source parameters successfully.
