Packstone

The matrix is micritic, but now partially dolomitized. Oolitic packstone can be found in the bank interior on the flanks of ooid shoals in modern Bahamas (Harris 1983) and similar environments in geological record, e.g., Permian Grayburg Formation, Midland Basin of USA (Barnaby and Ward 2007)..

Packstone microfacies were deposited in an agitated shoal environment, whereas grainstone microfacies occur as bars and channels and sand shoals. Abdulsamad et al. determined depositional environment of the Al Faidiyah Formation as open to restricted platform and it is correlated with Wilson’s facies SMF7 and SMF8. In the current work ...1. Inroduction. The identification of lithologies is the basis of reservoir characteristic research and geological modeling. It is significant in the fields of oil and gas development as well as mineral resource exploration (Yao et al., 2018).The complexity and heterogeneity of the geological environment result in the distribution of logging datasets is extremely unbalanced, which makes it ...
