Summary: A mathematical model describing thermohydrodynamic processes in an oil reservoir opened by a horizontal well has been developed. An inverse problem for estimating the filtration parameters of the oil reservoir is formulated. Temperature-time and pressure-time curves obtained simultaneously by several autonomous downhole devices placed in different sections of the wellbore of a horizontal well are used as initial information. It is shown that the solution of the inverse problem based on numerical simulation and regularization methods makes it possible to construct the inflow profile along the wellbore of a horizontal well and estimate the reservoir properties of bottomhole and remote zones of the reservoir and the radii of bottomhole zones in the vicinity of downhole devices.
