The complex structures of the channelised oil and gas fields in the area make it necessary to drill deviated wells through that seal. The maximum deviation angle at which successful drilling is possible strongly depends on the fraction of swelling clay minerals in shale composition, in particular...

The mineral composition of shale gas reservoir is complex and diverse and a universal mineral composition model is not available. In this study, the organic framework was introduced to construct petrophysical volume model of double skeleton mineral components in a sample of shale gas reservoir from ...
摘要: The XRD experimental research on the mineral composition of shale reservoirs is conducted.A digital analysis method for shale oil reservoir sensitivity is established.A sensitivity prediction method for shale oil reservoir porosity to external fluids is established....
Shales with similar mineral composition show a spectrum of equivalent medium mechanical properties due to differing particle morphology and mineral heterogeneity. The predominance of small particles and/or point-point contacts are conducive to brittle failure, in general, and especially so when quartz-...
The chemical and mineralogical composition of black shale is reflected in the quality of the surface waters and groundwater. Cu, Ni, Pb, U and Zn are recognised as major pollutants though the environmental impact is characteristically polymetallic just like the black shale occurrences. Hence, the ...
Obviously, the processes determining mineral composition of sandstones are more complex than simple mixing ones from source areas of different kinds. The discrepancy is great between observed and theoretically possible combinations of minerals.This is a preview of subscription content, log in via an ...
The mineral composition characteristics of this set of black shales are similar to those of highly productive shale gas in North America, for example shallow burial, low clay mineral and abundant brittle mineral, so the strata are conducive to the development of cracks and fractures. Thus, this ...

Mineral deposits have been historically classified in many different ways according to a number of geological parameters, viz., geological setting, host rocks, conceptual model, formation, etc. They are: (1) composition of the deposit (contained minerals/metals); (2) form of the deposit (size,...
