Seismostratigraphic Interpretation of the Paleocene and Eocene of West Tambaredjo Field, Central Coast of Suriname, Northeastern Region of South America

The Tambaredjo field is located in the Suriname coast line, and is part of the Guyana Basin passive margin. Deposition occurred since the Cretaceous, and the Paleocene-Eocene sediments are fluvial deltaic in origin. Subsurface logging, 3D seismic and biostratigraphic data were used to study the seismostratigraphic elements of this tertiary interval, which contains the main reservoirs in the area.

Identification of 2nd and 3rd order sequence boundaries and stacking patterns, led to the definition of a stratigraphic model. Five systems tracts along the Paleocene-Eocene interval of the Saramacca Formation were correlated.

Different seismic attributes were extracted from the systems tracts intervals to map potential sedimentary facies using neural network applications. Petrophysical properties such as porosity and net sand thickness versus seismic attributes were mapped implementing neural network in a Log Property Map application tool.

The major prospective sandstones occur in the early Paleocene Transgressive Systems tract, and channel systems were identified at the northwest section of the field. The amplitude attributes correlate with the mapped properties and follow the continuity and distribution of the lithofacies.
