INTRODUCTION

Considerable hydrocarbon reserves exists in offshore Bioko Island in Equatorial Guinea and are estimated at greater than 400 mmbbls. These reserves are interpreted to be located in distal fan deposits of the Niger Delta. This page examines the sedimentologic characteristics: (1) bed thickness; (2) sedimentary structures ( erosional surfaces, canyons, channels, troughs, depositional lobes, tectonic features – growth faults, diapirs ); (3) Textures and composition: (a) geometry and ( b) dimensions ( fan, channel, and levees); (4) depositional processes: sediment supply ( volume, source, etc.) and (5) the relationship to sea level fluctuations of the distal fan deposits of the deepwater fan channel systems of the Niger delta at the Zafiro oil field – offshore Bioko Island. The main objective of this page is to establish the relationship between the Pliocene distal fan deposits of the Niger delta in offshore Bioko Island with sea level change and climatic variations. The intent is to establish the character of the sands of these other deposits and use these to predict the character of the sediments found in the offshore of Bioko Island south of the Niger delta.
