Weblary height and Pittman r35 to map of water saturation. A similar approach has been adapted by Dakhelpour-Ghoveifel et al. (2024). They have used capillary pressure curves and specic borders between rock types to calculate water satu-ration and assign rock type to grids in transition zone. Here, H.D. Winland of Amoco used mercury injection-capillary pressure curves to develop an empirical relationship among Φ, Ka, and pore throat radius (r). He tested 312 different water-wet samples. The data set included 82 samples (56 sandstone and 26 carbonate) with low permeability corrected for gas slippage and … See more Analyzing air permeability (Ka and porosity (Φ) data separately to characterize rock quality can be deceiving. Analyzing Ka and Φ data using the Ka/Φ ratio or the r35 method is much more effective for determining quality. … See more Using Ka and Φ data separately to characterize reservoir rock quality is misleading. Consider the rocks shown in the SEM microphotographs in Figure 1. Flow unit 1 is a … See more On the plot in Figure 2, the contours represent a constant Ka/Φ ratio and divide the plot into areas of similar pore types. Data points that plot along a constant ratio have similar flow quality across a large range of porosity … See more Ka and Φ are standard components of many reservoir engineering wellbore flow performance equations. The Ka/Φ ratio reflects rock quality in terms of flow efficiency of a reservoir sample. When clastics and … See more
