Upward continuation is a method used in oil exploration and geophysics to estimate the values of a gravitational or magnetic field by using measurements at a lower elevation and extrapolating upward, assuming continuity. This technique is commonly used to merge different measurements to a common level so as to reduce scatter and allow for easier analysis.

The UC corresponds to a low-pass filter that attenuates short wavelength anomalies whose sources are near the surface (Jacobsen, 1987). This method allows not only to follow the evolution of a body in depth but also to estimate the average depth of the body (Jacobsen, 1987). hydraulic conductivity unit
