2D Ultra-Long Offset Seismic Survey In The Iranian Sector Of The Caspian Sea
Tuesday 18 April 2017
Geology Without Limits (GWL) in conjunction with Geological Survey of Iran (GSI) and Ministry of Mine, Industry and Trade (MMIT), plan to acquire 4 800 km of 2D seismic, gravity and magnetic data in the Iranian sector of the Caspian Sea (fig.1). The official agreement by parties was signed in Tehran 11th of March 2017.
The survey will be completed in Q3-Q4 2017 and will provide complex geophysical research with new high-end long-offset seismic data covering the entire Iranian sector of the Caspian Sea.
Data will be acquired with 12 km offsets of reflection waves plus ultra-long offsets up to 100 km of refraction waves to extend the total depth of the survey and build reliable velocity model for PSDM processing stage. FloatSeis UltraDeepImagin™ data acquisition technique (fig.2) will be implemented to reach ultra-long offsets and as a result to increase depth of the survey up to 25-30 km. GWL will provide brand new technology FloatSeisTM 2D plus Low Frequency Dual Source shooting which allowed to create a comprehensive picture of South Caspian geology, tying all of the major faults and cracks with providing the deep imaging of crust deformation and evolution of the region. For processing data will be used GWL TrueVelocitySolution (TVS)™ technology which is based on joint use reflected and refracted waves for creating precise velocity models in areas with complex geological situation.
Within the framework of the project it will carry out cooperation with leading scientific institutions that are actively involved in the problems of this region.
