Chemometric representation of molecular marker data of some Niger Delta crude oils

Chemometric representation of data is the most preferred and adopted method of research reporting in contemporary times. Data are easily discerned and interpreted. Molecular maker parameters of some crude oils from the Nigerian’s Delta region are chemometrically expressed after data treatment using multivariate statistical analyses, other graphical representations were the star diagram and triangular (ternary) plot. The results indicated discrimination of samples into two genetic families corresponding to their primary oil fields. These groupings were more obvious for results obtained via principal component analysis. Genetic groupings are principally due to compositional differences which are commonly attributed to unique source rock depositional environments and/or sourcing organic matter. The two families of oils identified have both terrestrial inputs, but differ comparatively by relative marine inputs.
