Solution of the Inverse Coefficient Problem of Heat and Mass Transfer from the Results of Temperature Measurements in a Horizontal Well

A mathematical model of heat and mass transfer in the “reservoir–horizontal well” system is proposed. An inverse coefficient problem is set to assess the filtration properties of an oil reservoir. Temperature change curves obtained using multisensor technology are used as initial information. A computational algorithm for solving the inverse coefficient problem based on regularization methods is proposed. It allows one to build an inflow profile along the borehole of a horizontal well and evaluate the filtration properties of the reservoir under various fluid flow regimes in the borehole.
