Title

Sedimentological and Palynological Characteristics of the E2.0 Reservoir (Middle Miocene) in the Kolo Creek Field, Niger Delta

Abstract

The E2.0 Reservoir in the Kolo Creek field is an offlap sequence in which seven deltaic depositional sub-environments are recognized. Several criteria were studied on 50 m long cores from two boreholes. Ten lithofacies were recognized from grain size, textures, sedimentary structures and trace fossils. Visual and statistical analyses defined two environmentally-controlled palynofacies associations. Mudstones and muddy heteroliths constitute Palynofacies Association A/C, which is rich in light-textured components and in lath-shaped wood fragments. Palynofacies Association B/D is rich in black debris and mainly angular, equidimensional wood fragments and is restricted to sandstones and sandy heteroliths.
