Azerbaijan's Caspian Geo launches 3D seismic surveying at Goshadash structure in Caspian Sea

BAKU. Nov 11 (Interfax) - Azerbaijan's geophysical company Caspian Geo has commenced 3D seismic surveys at the promising Goshadash prospect in the Azerbaijani sector of the Caspian Sea, the company posted on social media.

"On November 5, the 3D seismic survey project at the Goshadash structure officially entered its operational phase. [...] Two vessels have departed from the port, heading toward the Goshadash structure," according to the post.

The company said that the deployment of two additional, fully equipped vessels expands the capacity to conduct multiple offshore projects simultaneously in the Caspian region.

Representatives from Caspian Geo and other project stakeholders discussed matters related to safety, coordination, and the organization of joint operations, according to the post.

As reported, the State Oil Company of the Azerbaijan Republic (SOCAR) conducted engineering-geophysical surveys at the prospective Goshadash site between March and June 2026 as part of preparations for offshore 3D ocean bottom node (OBN) seismic exploration. This technology involves placing seismic sensors on the seabed to acquire three-dimensional data on the subsurface structure.

The Goshadash structure is located in the northeastern coast of the Absheron Peninsula, approximately 15 km from the shore. The water depth in the area ranges from 10 to 50 meters.

Malaysia's Petronas and Russia's Lukoil had previously expressed interest in developing the structure.
