Abstract
Summary
In late 70s, hydrocarbon exploration in Blach Sea concentrated on the shallow water shelf area. The exploration focus has change for the frontier deep water settings in the last decade, with the discovery of Domino gas field. The hydrocarbon exploration brought significant amount of new data, both with local and regional character. These include 2D and 3D seismic, Gravimetric and Magnetic data, with a reasonable amount of well data, essential for models calibration and validation. The integration of these new data brings new insights over the basin architecture and evolution. One of the key aspects for basin kinematics and petroleum system modeling is the continental oceanic boundary (COB) definition, especially helpful to assess the paleo heat flow in the Black Sea. The exploration also requires a better constrain over the basin evolution and architecture with the continental oceanic limit being one of the most important feature for the basin modelling of the petroleum system.
Our work focuses on the definition of the COB offshore Bulgaria and identification of crustal domains, by integrating the seismic interpretation of the 3D and a dense grid of 2D data both PSTM and PSDM with interpretation and inversion of GravMag data.
