If land-satellite data had been available and applied to areas over which giant fields were found, how effective would have been the use of the data in the exploration effort and what kind of useful geologic information would have been generated from the satellite images? This question obsessed the author and prompted the effort to find an answer by obtaining satellite images of

15 existing giant fields in various parts of the world and interpreting whatever geologic data the images provided.

At this writing (December 8, 1978), the study has not been completed, but it seems apparent that the images would have been of considerable value in exploring for and pin-pointing the locations of most of the giant fields under study. Such a conclusion indicates that land-satellite images and remote-sensing data should be a top priority in the search for the future giants to be found in the remaining prospective areas of the earth.
