The Py-GC/MS results of the study carried out on two groups of vitrinites (perhydrous and non-perhydrous) of di€erent age and properties and on a trimaceralic coal associated with one of the perhydrous group are discussed. Such a study provides information about the e€ect of natural hydrogen enrichment on vitrinite structure at the molecular level. Moreover, the in ̄uence of the di€erent conditi...

microfacies and depositional environments interpretation of asmari and jahrum were studied in boreholes 2, 10 and 11 in gol- khari oil field. based on petrographic criteria, fauna assemblages, biofacies and sedimentary textures, 21 carbonate microfacies and 3 non- carbonate petrofacies were recognized. these microfacies were deposited in distinct depositional environments including tidal flat, ...

A hierarchical geostatistical analysis is conducted on a high-resolution, multiscale hydraulic conductivity (lnK) map, created by scaling up an experimental stratigraphy. Unlike a previous study which evaluates lnK variograms within individual depositional environments, this study analyzes deposits (or samples) that incorporate multiple depositional environments. Based on conductivity cutoffs s...
