The invention relates to the analysis of fluid flow paths in a subterranean hydrocarbon reservoir by analyzing rock cuttings from drilling new wells. Previously injected tracers may be isolated from the rock cuttings and analyzed with reference to the history of when and where they were injected. In this way, further information about fluid flow paths in the reservoir may be obtained from different locations in the reservoir without injecting fresh tracers. Cuttings may be analyzed from either production or injection wells.
