Heating of Oil Well by Hot Water Circulation

When highly viscous oil is produced at low temperature, large pressure drop will significantly decrease production rate. One of possible solutions to this problem is heating of oil well by hot water recycling. We introduce and analyze the mathematical model of heating the oil well. The model consists of three hyperbolic equations coupled with one Volterra integral equation. Under simplifying assumptions that specific heats and densities of various materials are independent of the temperature, the proposed model becomes linear. Further we construct and examine numerical method for the model and present some simulations results
