Cuttings are the least desirable because they are the least site specific of the sample types and because they disproportionately represent the least porous parts of a reservoir. The most porous parts commonly disintegrate into constituent grains. Moreover, it is difficult to evaluate the homogeneity of reservoir characteristics because of the small size of cuttings. | Cuttings are the least desirable because they are the least site specific of the sample types and because they disproportionately represent the least porous parts of a reservoir.
