Seismic activity in Caspian Sea causes cracks in oil and gas fields: chief seismologist


The seismic activity in the Caspian Sea is causing cracks in oil and gas fields, Gurban Yetirmishli, director of the Republic Seismic Survey Center of Azerbaijan National Academy of Sciences, told a press conference on Thursday, APA reported. 

 

He noted that there are potentially powerful earthquake focuses in the oil- and gas-rich Caspian Sea.

 

Yetirmishli said the occasional earthquakes that are noticed in Absheron and Baku are linked with the earthquake focuses existing in the Caspian Sea.

 

According to him, the Caspian Sea is rife with both mud volcanoes and earthquake focuses.

 

“The earthquake focuses are found in the Caspian Sea from its north all the way to its south, which stems from depth cracks,” he added.

 

The chief seismologist said there are no seabed seismic stations in the Caspian Sea.

 

“Although three such seabed stations were purchased, it has not been possible to install them so far. Locations for them have been pinpointed but they have not been installed yet due to certain difficulties,” Yetirmishli said, adding. “We’re hopeful that this problem will be solved in the near future. Negotiations in this respect are ongoing with foreign experts. It is possible to complete these works within any grant project. It is very important for us.”

 

According to him, the study of depth structure of seabed, identification of its potential, tomography, risk assessment in setting up communication lines and seismic micro-zoning are of great importance.

 

Yetirmishli went on to say that seismic activity in any earthquake focus unintentionally affects the Gunashli, Azeri and Chirag oil and gas fields.

 

“The seismic activity in the Caspian Sea is causing cracks in oil and gas fields. Oil will flow in any direction if there are crack within the oil field,” he said.
