Abstract
The palynofacies and petrography of the Gbekebo well in the Dahomey Basin are thoroughly examined in this project. Using petrographic analysis and palynological data (palynofacies), the study seeks to evaluate the well's depositional environment and examine its sedimentary components. Combining these methods has helped with oil and gas development in the Dahomey Basin by shedding light on the region's reservoir features and paleoenvironmental conditions.
In order to explore the region's hydrocarbon potential, the Gbekebo well was drilled in the
Dahomey Basin. The palynofacies and petrographic examination of the well's sedimentary sequences are the main subjects of this investigation.
To identify and measure different organic matter components, such as terrestrial palynomorphs (pollen, spores, plant debris), marine palynomorphs (dinoflagellate cysts, acritarchs), amorphous organic matter (AOM), and inertinite, palynofacies analysis entailed the preparation and microscopic examination of palynological slides. Rebuilding the paleoenvironment, identifying
the terrestrial versus marine origin of organic matter, and determining the degree of oxidation
during deposition are all made possible by this research. Different palynofacies were identified
based on the distribution and relative abundance of these elements, and these were subsequently
connected with particular depositional environments.
Thin slices of rock samples were subjected to petrographic investigation in order to ascertain the
sedimentary rocks' mineralogical composition and textural properties. This required utilising
polarised light microscopy to identify and measure the framework grains, matrix and cement.
The findings will help to improve the stratigraphic framework and offer insightful information for
upcoming hydrocarbon exploration projects in the area. Additionally, this research will improve
our knowledge of the petrography, and palynofacies of the well.
