Turkmenistan: RWE completes Caspian seismic survey

RWE Dea, Hamburg, has collected a land and transition zone 3D and 2D seismic survey on Block 23 in the Caspian Sea off southern Turkmenistan, the first survey of its kind in the country.

The company shot about 400 sq km in less than 4 months with 400 persons using special vessels and vehicles. Geologists and geophysicists are interpreting the data. RWE was awarded the block in 2009.

Cables with receivers were laid seamlessly from the mainland as far at 10 km into shallow water. Airgun arrays were deployed in the water, and Vibroseis was used on land.

With this seismic survey, RWE Dea explored geological structures of Miocene and Pliocene age at depths of 3,000-6,500 m. An extensive environmental study preceded the survey.
