Resumen
This paper describes the development of a transient technique to measure thermal diffusivily and conductivity of porous samples. The method uses the film heat sensor to probe heat flux. Temperature and heat flux are measured dynamically allowing conditions to vary in time at the point of measurement. The data are then treated by a deconvolution algorithm, rendering results proper to simpler models for the same geometry. The numerical treatment in the deconvolution procedure was verified for a hypothetical case. The method was finally tested in the laboratory, with experiments made on samples of natural rock. © 1993 Pergamon Press Ltd. 36 10 2565 2573 Miller, Mohanty, Thermal and Thermo-Mechanical Effects in Thermal Oil Recovery (1991) Center for Enhanced Oil and Gas Recovery Research Annual Report, , Category B Tye, (1969) Thermal Conductivity, , Academic Press, New York Scott, Seto, Thermal properties measure-ments on oil sands (1970) J.
