A Semi-analytical Model For The Prediction Of CO2 Injectivity Into Saline Aquifers Or Depleted Hydrocarbon Reservoirs

Novel/Additive Information: The paper presents a simple and computational fast method to predict CO2 injectivity and well pressure as a function of time. The application of superposition in time - a method usually associated with solving linear problems - is demonstrated to adequately solve the complex non-linear problem of CO2 injectivity. Because the method includes material balance, it can help to define storage efficiency factors.
