Abstract
A method and a system are provided to characterize subterranean formations, which includes extracting drill cuttings from a drilling fluid, and grouping the drill cuttings into a group of cuttings based on a time of arrival of the drill cuttings at the Earth's surface, wherein these steps can be repeated at least once to provide a plurality of groups of drill cuttings that arrive sequentially at different recorded times that correspond to different downhole locations.
