WebThe term “petrofacies” (which comes from “petrophysical facies”) extends the facies concept to pore networks. Although this name is commonly (but not exclusively) used for this purpose, the range of published definitions is fairly broad, as pointed out by Sullivan et al. (2003).Some authors intermingle notions of petrofacies with electrofacies and … WebLithofacies discrimination intrinsically has ambiguity, and the depositional sequences of the study area comprise shales, fine-grained sands, and silts. So it needs to reduce the …
WebThe lithofacies classification is essential for oil and gas reservoir exploration and development. The traditional method of lithofacies classification is based on “core calibration logging” and the experience of geologists. This approach has strong subjectivity, low efficiency, and high uncertainty. This uncertainty may be one of the key factors … WebPetrofacies and depositional lithofacies are discordant, indicating that diagenetic processes did not respect lithofacies boundaries. The best reservoir rocks (sucrosic …
