Satellite imagery revealed a small oil spills in the North CaspianA group of small spots of oil emitted from underwater sources were detected in the Kazakh sector of the Caspian Sea in late May — early June, the experts explain the reasons for activation source at the bottom of the Caspian Sea, said the Engineering Technology Center (ETC), "RDC".

According to satellite data, a group of spots in the form of curved filaments in width from 50 to 150 meters and a length of 300 meters to three kilometers were found in three areas of the sea in the sector of Kazakhstan to the north-west of the peninsula Tub-Karagan (Mangyshlak). Experts "ScanEx" connect their appearance with the activation of griffins — channels uncontrolled release of oil, gas and water, which may arise from natural causes, and the drilling and well operations.

According to a senior researcher at the Institute of Oceanology of the Russian Academy of Sciences Shirshov Andrei Ivanov, small spots and clusters recorded in the north of the Caspian Sea from the beginning of the regular satellite monitoring in 2007. In particular, a similar contamination in the same area were found in SAR images in 2010-2011, but then the hard evidence of their origin griffin has been found. New data confirm the assumption of experts, said Ivanov.

Senior Researcher, Institute of Geosphere Dynamics RAS Boris Golubov said that large deposits of oil and gas in the area, which is related manifestations Gryphon while could be found, despite the number of wells drilled. Neftegazonost Mesozoic and Cenozoic sediments (up to 250 million years ago) has been proved by geological and geophysical studies, but it's hard to say which of the horizons of occurrence "worked" at this time, and what factors led to activation of griffins.

"It is possible that the" trigger "on a sea trip griffins continue Tub-Karagan shaft could be recorded at the same time, a cascade of earthquakes with magnitudes ranging from 4.0 to 5.6, concentrated in the north-western part of Azerbaijan on the border with Dagestan. must not disregard other factors destabilizing the subsoil. Eventually, of course, one thing — clear signs of growing geodynamic activity tectonic basin of the Caspian Sea ", — concluded Golubov, whose words are reported.
