The impacts of diagenetic facies on reservoir quality in tight sandstones

Open Geosciences, 2020
The impact of diagenetic minerals and the characteristics of pore structures on reservoir qualities has been studied separately in the past years. However, the difference in the reservoir quality with different pore structures and having same or similar ...
