Microstructure Parameter Estimation in Permeability Calculation of Well Cement during Early Hydration by a Simple Particle Expansion Model

Abstract— The inter-connected pores of cement after displaced into wellbore is believed to contribute for fluids migration. It cannot be accurately evaluated using the present sonic and acoustic methods due to its density based principles. Impedance technique is applied at elevated temperature a...
