Abstract

Summary

The structural interpretation of 2D seismic data in the Chukchi platfrom, the Russian sector of the Chukchi Sea, reveals five salt diapirs and associated salt structures in grabens. The evaporitic composition and Lower Carboniferous age of these structures can be derived from the structural associations, field studies of the adjacent Wrangel Island, high seismic velocities and low gravity anomalies, and global geodynamic and paleo-geographical reconstructions. Salt diapirs obtain various geometries and spatial orientations depending on the their belonging to different structural domains of the Chukchi platform. Salt mobilisation took place in the (Early)-Late Cretaceous and Tertiary, which is based on the presence of salt withdrawal synclines in the correspondent strata. Three groups of plays related to salt tectonics in the Chukchi platform are defined and ranked. The most promising direction of hydrocarbon exploration is associated with salt structures flanks and drape structures in combination with the Carboniferous-Jurassic strata.
