ExxonMobil has been exploring in the Romanian sector of the Black Sea since 2008, with our partner, OMV Petrom. After acquisition of a 3D seismic survey in 2009, we drilled the Domino-1 gas discovery in 2012. This was the first deepwater discovery anywhere in the Black Sea. This discovery was followed by acquisiiton of a second 3D survey, the largest that had ever been acquired in the Black Sea at that time. The results of the first well and both 3D surveys were then used to plan an extensive drilling program to appraise the Domino discovery and conduct further exploration in the block.

The interplay of local and global controls on accommodation and sediment supply generates basin-specific sequence stratigraphic frameworks that record cyclicity at multiple scales. A scale-independent approach to methodology and nomenclature is key to the standard application of sequence stratigraphy. There are parameters that vary with the case study, including the types of data available, the resolution of the data available, and the local conditions of accommodation and sediment supply. A standard methodology and nomenclature must remain independent of these variables, and rely on core principles that underlie the application of all alternative models.
