Characteristics and main controls of nano-pores in the Lower Silurian Longmaxi shale, Sichuan Basin

Shiyou shiyan dizhi, 2020
The Upper Ordovician Wufeng-Lower Silurian Longmaxi shale is the only yield layer of commercial deve-lopment of shale gas in China at present. However, there are significant differences in the production of individual shale gas wells in different areas ...

Shale gas investigations in Denmark: Lower Palaeozoic shales on Bornholm [PDF]

Geological Survey of Denmark and Greenland Bulletin, 2011
The Cambrian to Lower Silurian succession in Denmark is mostly composed of organic-rich black shales that were deposited in an epicontinental sea during a period of high global sea level (Haq & Schutter 2008). The mid-Cambrian to early Ordovician Alum Shale was intensively studied in the 1980s for its source-rock properties (e.g.

The impact of multistage fluid and diagenetic environmental coupling on the development of deep clastic rock reservoirs: A case from the Zhuhai Formation, Wenchang A Sag, Zhujiangkou Basin

Energy Exploration & Exploitation
Fluid modification critically affects the quality of clastic rock reservoirs. At present, the mechanism of multistage fluid alteration in clastic rock reservoirs under deep burial conditions is still a matter of debate.

Geological factors controlling high flowback rates of shale gas wells in the Changning area of the southern Sichuan Basin, China

Frontiers in Earth Science
In the Changning block of the southern Sichuan Basin, the shale gas wells in the Upper Ordovician Wufeng Formation to Lower Silurian Longmaxi Formation (Wufeng–Longmaxi) demonstrate significant difference in flowback rate of fracturing fluid, given the ...

Molecular-Scale Considerations of Enhanced Oil Recovery in Shale

Energies, 2020
With only less than 10% recovery, the primary production of hydrocarbon from shale reservoirs has redefined the energy equation in the world. Similar to conventional reservoirs, Enhanced Oil Recovery (EOR) techniques could be devised to enhance the ...

Book Review ~ Handbook of Online Learning Innovations in Higher Education and Corporate Training. Editors: Kjell Erik Rudestam and Judith Schoenholtz-Read

International Review of Research in Open and Distributed Learning, 2003
If you take this volume at face value, based on the title, you will likely wonder, as I did, how the combination of “online learning,” “innovation in higher education,” and “corporate training” could coherently co-exist within a “handbook.” However, the ...
