Mineral indicators of percolation effects in production of oil-saturated reservoir

Krinari G.; Eskin A.; Korolev E.; Eskina G. (2016)

In the simultaneous filtration of the water and oil in a reservoir each of the phases is moved on the microlevel by their local channels. Herewith, percolation effects can begin when blocking of traffic through various ...
Mixed-Layer clay minerals as indicator of diagenesis processes in oil bearing rocs

Krinari G. (2014)

To optimize oil production technologies must take account of the extent and causes of secondary changes of structures of illite-smectite phase in oil bearing rocs as result of diagenesis processes, but ordinary relation ...
Mononuclear Mn(II), Co(II), and Cu(II) pivalates

Fursova E.; Romanenko G.; Sagdeev R.; Ovcharenko V. (2014)

Mononuclear Mn(II), Co(II), and Cu(II) pivalates were synthesized for the first time. They were isolated as salts with a composition NBu 4[MPiv3], where Piv is the pivalate anion. In the structure of the [MnPiv3] and ...
