This thesis is concerned with examining the dynamics of CO<sub>2</sub> injected into a porous layer. Solutions are found for flows corresponding to various different faulting and background flow scenarios for a confined inclined porous layer. The speed of advance and shape of the injected fluid front are calculated. It is found that different boundary conditions associated with different faulting scenarios can lead to very different spatial distributions of CO<sub>2</sub>. Investigation is made into how a confined layer may begin to fill with injected fluid when the injected current approaches a fault. The different solutions for different faulting scenarios can indicate radically contrasting injection strategies. Some possible consequences of a mixing reaction in a porous layer are also addressed. The understanding gained from the solutions found may help in the interpretation of remote geophysical observations and so contribute to the assessment of safety and the optimisation of injection strategies for carbon dioxide sequestration scenarios.
