Patent ID: 8401794

Claim:
A method of improving a resolution of an induction logging tool including processing geological log data obtained from use of one or more logging tools and including at least a first log and at least a corresponding second log that exhibit an attribute to an unequal extent, the method comprising the steps of: transmitting energy through a geological formation; receiving energy that is indicative of characteristics of the geological formation; converting the received energy into signals; generating the first log and the second log; and incorporating into the first log characteristics of the second log that confer improvements in the said attribute, characterised in that the incorporating step includes modulating the extent of incorporation into the first said log of the said characteristics without distorting geologically significant information in the first log; wherein the attribute of the logs is the vertical resolution; wherein the vertical resolution of the first log is lower than the vertical resolution of the second log; and wherein the first log is derived from the signals generated in the logging tool by an induction long-spaced detector or receiver.
