Small-Scale Diagenetic Heterogeneity Effects on Reservoir Quality of Deep Sandstones: A Case Study from the Lower Jurassic Ahe Formation, Eastern Kuqa Depression

Geofluids, 2021
The Lower Jurassic Ahe Formation is an important exploration target for deep clastic reservoirs in the eastern Kuqa Depression. The Ahe Formation sandstones show heterogeneous porosity and permeability petrophysical properties. These properties have been

Machine learning-based classification of petrofacies in fine laminated limestones [PDF]

Anais da Academia Brasileira de Ciências
Characterization and development of hydrocarbon reservoirs depends on the classification of lithological patterns from well log data. In thin reservoir units, limited vertical data impedes the efficient classification of lithologies.

Taphofacies and Petrofacies Theoretical Marine Models Applied to the Coquina of the Amaral Formation (Lusitanian Basin, Portugal)

Journal of Marine Science and Engineering, 2021
The Amaral Formation has a wide geographic distribution within the Lusitanian Basin, at the western Iberian Margin (Portugal). The different depositional contexts for this unit enabled the distinction of three sectors: lagoon, lagoon-barrier, and marine ...

Recognition of Oil Traps in the Kopet-Dagh Basin (Northeastern Iran) Using Fusion of Seismic Attributes, Petrophysical Logs and Geological Data [PDF]

Journal of Petroleum Science and Technology, 2022
Integrated analysis of oil traps, especially those related to facies changes, is far more complicated than reservoirs related to structural traps. The most useful way to identify these complex subsurface structures directly related to facies change is to
