Figure 6-1. Calculated PFRD values for the Rhinestreet shale (fp = 37.8%) using empirical algorithms. Shaded interval defines the PFRD range based on comparison of the Rhinestreet fp with published normal compaction curves for shale. BB = Baldwin and Butler (1985); FD = Falvey and Deighton (1982); GL = Gallagher and Lambeck (1989); HA = Hansen (1996); HGY = Hegarty et al. (1988); H = Hermanrud et al. (1998); HG = Huang and Gradstein (1990); LR = Liu and Roaldset (1994); SC = Sclater and Christie (1980); T = Tingay et al. (2000); V = Velde (1996); MBD = modeled maximum burial depth of the Rhinestreet shale. The majority of calculated PFRDs fall within the depth range estimated from comparison with published compaction trends.
