Abstract: Disclosed is a method for imaging a subterranean formation traversed by a wellbore using a tool comprising a transmitter for transmitting electromagnetic signals through the formation and a receiver for detecting response signals. In the method the tool is brought to a first position inside the wellbore, after which the transmitter is energized to propagate an electromagnetic signal into the formation. A response signal that has propagated through the formation is detected, and a derived quantity for the formation is calculated based on the detected response signal for the formation. The derived quantity for the formation is plotted against time. The tool is moved to at least one other position within the wellbore and the procedure above is repeated. Then an image of the formation within the subterranean formation is created based on the plots resulting from the repeated procedure above.

Abstract: The present invention provides a method and apparatus for arriving at true relative amplitude destretched seismic traces from stretched seismic traces.  The method compensates for offset varying reflection interference effects due to normal moveout. Stretch factors .beta. and also input spectra are determined for NMOR stretched seismic traces. Estimates are then made of stretched wavelet spectra from the input spectra. A destretched wavelet spectra is then obtained. Shaping correction factors are determined by taking the ratio of the destretched wavelet spectra to the stretched wavelet spectra and are applied to the input spectra of the stretched traces to arrive at a destretched trace spectra. True relative amplitude scaling factors are computed by taking the ratio of a true relative amplitude property of the destretched wavelet spectra to a corresponding true relative amplitude property of the stretched wavelet spectra. Finally, the true relative amplitude scaling factors are applied to the destretched trace spectra to arrive at true relative amplitude destretched seismic traces.
