Reservoir quality

This element represents an evaluation of the controls on observed variations in reservoir quality. A variety of statistical and graphic techniques are employed to evaluate variations in reservoir quality and the degree to which this variation is controlled by various geological factors. The availability of a digital dataset of core, lithological and petrographic analyses greatly aids this process and the relative influence of primary depositional factors (grain size, clay content, facies etc.) and secondary or diagenetic influences (cementation, dolomitisation, fracture formation etc.) will be evaluated. The degree of linkage between primary and secondary influences is also investigated such that, with robust depositional and diagenetic models, the potential for predictive interpretations is maximised. Such studies focus on defining and explaining variations in reservoir quality by integrating the full available dataset. Integration of results with available published and unpublished data allows a consideration of regional issues.
