A method is defined for determining whether a rock is capable of functioning as an oil reservoir has had or presently contains oil. The method includes the steps of: -cleaning a sample of the rock in a manner such that at least some of any adsorbed oil on the rock will remain and any oil inclusions within the rock remain intact; -irradiating the cleaned sample with fluorescence inducing electromagnetic (typically UV) radiation and measuring emitted (typically UV and visible) radiation from the sample; and-comparing the emitted radiation measurement against a similarly determined measurement from a rock sample of a known oil-producing reservoir, to determine whether or not the rock has had or presently contains oil. In a variation of the above method, the sample of the rock is cleaned step-wise in a manner that removes other than adsorbed oil on the rock, with a final cleaning step including contacting the sample with a solvent into which some adsorbed oil may be extracted. The solvent extract can then be analysed for oil (typically by irradiating the solvent with fluorescence inducing electromagnetic (typically UV) radiation) and the analysed oil then compared against a similarly derived and analysed oil from a rock sample of a known oil reservoir to determine whether or not the rock has had or presently contains oil. Typically the rock is granular and typically the cleaning step involves disaggregating the rock into single grains, prior to cleaning.
