A method of detecting induced changes in the rock properties of subterranean formations. The preferred use of the method is in determining the presence and orientation of induced fractures in the formation. In this use of this method, the formation is first pulse tested between the well to be ...
At the end of C and the early stage of deposition of Wuerhe formation (P2w), the paleo climate became warm and humid, and the salinity of water body became small. Meanwhile, the oxidizability of water body gradually became stronger. At the deposition stage of Jiamuhe Formation (P1j), ...
It is found that, under complex heat-force conditions of loading during the exploitation of cryolite rocks, the metal in the active surface of the rock cutting element undergoes intense softening as a result of the formation of a secondary structure, namely, frictioninduced sorbite. As a result...
graptolitic black shales of the pre-glacial Wufeng Formation and the post-glacial Longmaxi Formation and are known as deep-water graptolitic black shales6,7,12. Anoxia was widespread and expanded repeatedly in the Late Ordovician–early Silurian ocean during the deposition of black shales, and ...

The formation of the Ontong-Java flood-basalt plateau in the western Pacific has been identified as a potential trigger of OAE 1a, as a source of volcanogenic CO2 to the atmosphere, thereby, enhancing Earth’s greenhouse conditions (Erba, 1994, Leckie et al., 2002, Weissert and Erba, 2004...
The isotope effect on the local structure of liquid water at room temperature is studied by x-ray Raman spectroscopy. The difference between the room-tempe... U Bergmann,D Nordlund,P Wernet,... - 《Physical Review B》 被引量: 73发表: 2007年 Investigation of the Formation Process of Photo...
A model was developed for calculating the change in gas composition in the pool during its formation by vertical migration. A conical trap with varying cap-rock thickness was considered. Amputations were made for different thermodynamic conditions, different initial states of the gas entering the ...
Each rock sample underwent three consecutive heating and cooling cycles. Significant irreversible changes in the properties due to thermal crack formation could be observed. After the first thermal cycle, both thermal diffusivity and conductivity dropped to about 75% of the initial value at room ...
