This invention relates to methods and systems for displaying geological
formation data obtained through well logging in the technical field of
petroleum engineering. In one embodiment of this invention, two or more
cylindrical surfaces are provided each representing a depth of
investigation. The cylindrical surfaces can be dissected into different
sectors along azimuths of interest to the human operator. Images of
formation information data are attached to (or exposed by) cylindrical
surfaces and wings exposed by dissection. Each sector can be displayed
individually or together with other sectors so that the human operator
can easily analyze the results. Further, the systems and methods can be
used to display not only raw well logging data or processed well logging
data, but also interpretations of the analysis so that a person
unfamiliar with well logging analysis can easily comprehend the results
of the analysis.
