Abstract: Sequence Stratigraphic Analysis Of The Samotyno-More Well, Offshore Bulgaria And Its Relationship To Hydrocarbon Potential In The Black Sea

Cuttings samples and core samples from the Samotyno-More well, offshore Bulgaria was analyzed for planktonic and benthic foraminifers, calcareous nannofossils, diatoms, and palynomorphs for biostratigraphic age and paleobathymetry and well-log sequence stratigraphic analysis.

Sixteen (16) Sequence Boundaries and fifteen (15) Maximum Flooding Surfaces ranging in age from 58.5 to 33.0 Ma were recognized through 3140 meters of section.

The T.D. of the well was in the Late Cretaceous Cenomanian Stage.

The 360 meters of sediments in the late Paleocene sequences 58.5, 55.0, 54.5 and 54.2 Ma were deposited in a lower bathyal environment.

The early Eocene sequences 53.0, 52.0, 51.5, 50.5, 50.0 and 49.5 Ma are represented by 1290 meters of sediments that were deposited in a lower bathyal environment.

The 885 meters of middle Eocene sediments in the 48.5, 46.5, 44.0 and 42.5 Ma sequences were deposited in a middle bathyal environment. There is an unconformity at the base of the 36.0 Ma sequence cutting out the late middle and late Eocene sequences.

The early Oligocene sediments in the 36.0 Ma sequence are represented by middle to upper bathyal sediments. Within the 33.0 Ma sequence there appears to be a rapid shallowing.

The lowstand basin floor fans and channel sand with proper seals and charge are potential reservoirs in the 54.2 to 49.3 Ma sequence.
