The research on the effect of paraffin sedimentation to the well productivity

When reservoir conditions changes,paraffin may deposit on the surfaces of porous media or on pipe walls in the form of crystals resulting in a plugging giving serious troubles in oil production.A thermodynamic model is suggested in this paper to predict the deposition of paraffin from the crude oil.This model uses the equation of state to describe solid phase and liquid phase simultaneously.And then calculate the change of porosity and permeability after paraffin sedimentation,and calculate renew the well productivity.
