N2 - The linear Backus-Gilbert theory is used for the deconvolution problem of continuously logged borehole temperatures. The main elements of the theory and some numerical and experimental results are given. The accuracy and resolution of the temperature and temperature gradient records are determined by the logging velocity, the probe time constant, the sampling period, the statistical accuracy of data, and the characteristics of the inverse filter. By applying the inverse approach the interrelation between parameters is studied, and the trade-off between accuracy and resolution is emphasized. The inverse method yields well defined temperatures and temperature gradients with associated standard deviations and averaging functions. It is suitable for the processing of continuously logged temperature data with reference to application in terrestrial heat flow and stratigraphic studies.
