Seismic profile showing carbonate buildup partly drilled by Chopin-1 well (see Figure 2 location); ( a ) uninterpreted standard amplitude display, ( b ) cosine of the instantanous phase, ( c ) for location); ( a ) uninterpreted standard amplitude display, ( b ) cosine of the instantanous phase, pseudo-relief, ( d ) interpreted seismic data. Abbreviations: tcb—interpreted top of carbonate buildup, ( c ) pseudo-relief, ( d ) interpreted seismic data. Abbreviations: tcb—interpreted top of carbonate buildup, J3—top of the Upper Jurassic, Kcn—top of the Cenomanian, SSYNT—synthetic seismogram. Yellow box indicates discontinuous reflection pattern (chaotic seismic facies) present along slope of the carbonate buildup, associated with talus
