The method uses a correlation developed for estimating Biot poroelastic coefficient as a function of process speed (the ratio of permeability and porosity) and pore throat aperture (rp35). Results indicate that the proposed Pickett plots...

A consistent Pc derivative value can be used to obtain irreducible water saturation and corresponding maximum capillary pressure. After Pc curve fitting for multiple cores, correlations can be developed for the parameters...

Fluid heterogeneity mapping using crude fingerprint analyses was performed to understand the variability of the oil biodegradation level across the field. PVT data provided reservoir GOR and supported the oil chemical variation. Biomarkers correlations were...

... Abstract As fields become mature and more laboratory data is available from specific geographical locations, it is possible to characterize, classify crude oils and develop or modify published correlations to better predict oil PVT properties. This paper shows the results from the attempt...
