GWL to survey offshore Iran

April 18, 2017

Geology Without Limits (GWL) in conjunction with Geological Survey of Iran (GSI) and Ministry of Mine, Industry and Trade (MMIT), plan to acquire 4800 km of 2D seismic, gravity and magnetic data in the Iranian sector of the Caspian Sea.

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.

GWL said data will be acquired with 12km offsets of reflection waves plus ultra-long offsets up to 100km 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 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 FloatSeis2D 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, GWL TrueVelocitySolution technology will be used. It based on joint use reflected and refracted waves for creating precise velocity models in areas with a complex geological situation.
