Our Thomeer parameter databases can be manipulated to extract PRTs, correlations and statistics for each reservoir. Clerke has defined PRTs as objects in the three dimensional space of Thomeer parameters. Porositon combinations are used to construct meaningful petrophysical rock types. Petrophysical rock types (PRTs) are defined by Clerke et al.

The T2 data and the hydrocarbon density, water density, free water level, and paleo-water level of the formation are processed to obtain parameters of Thomeer hyperbolas that closely conform to water saturation values obtained from the other well logs. The Thomeer hyperbolas so determined are converted to capillary pressure curves.

The Thomeer parameters are intuitive: the sorting parameter of the pore-throats (G), the maximum size of pore-throats (P d), and the porosity (B∞). 2013-08-01 · The details in position and shape of the hyperbola are determined by the three Thomeer parameters: P d, which is the “minimum entry pressure” or “threshold pressure”, related to the largest connected pore throat diameter; G is the “pore geometrical factor” related to the range of pore throat diameters and B v ∞, which is the “fractional bulk volume occupied” by mercury at P c =∞. Thomsen parameters are dimensionless combinations of elastic moduli that characterize transversely isotropic materials, which are encountered, for example, in geophysics.
