ABSTRACT:
A method of method of logging an invaded geological formation comprises the steps of:(i) operating plural receivers in order to receive signals generated by one or more transmitters and thereby create logs of overlapping lengths of a bore formed in the said geological formation, the respective said receivers logging distinct depths of penetration, as previously defined, of the geological formation measured with respect to the bore;(ii) recording the resultant values in a two-dimensional plot one of whose axes represents the respective depth of penetration of the said formation to which each said log corresponds;(iii) establishing whether the resulting plot appears to approach an asymptote; and if so(iv) determining the value of the asymptote.
