Reservoir Quality
Chemostrat has also established a work programme to integrate elemental and mineralogical data with petrophysical parameters to enhance reservoir quality modelling. For example, elemental data can also be used to calculate mineralogy and provide an estimate of TOC and proxy for relative brittleness (RBI) that following calibration ensures elemental data can be multipurpose, practical and more cost effective as a means of modelling which is critical for well completions in shale plays. Elemental data can also be used to refine the petrophysical modelling in carbonate plays detecting subtle variations in dolomite, anhydrite or salt that can hold the key to reservoir quality. Furthermore, mineral abundances can be measured from elemental data in turbo-drilled cuttings where textural mineralogical characteristics have been destroyed by the drilling process.
