Abstract:

Lithofacies characterization and hydrocarbon play elements of Oligocene to early Miocene sediments in Greater Ughelli Depo belt Niger Delta Basin were carried out using a total of One hundred and ninety (190) Ditch cutting samples, with the aim of identifying the lithofacies and hydrocarbon play elements for the well succession. The sediments were characterize on the basis of colour, texture (grain size, shape and sorting), mineral types and accessories. A total of thirty (30) lithofacies zones which include: Sandstone, Shale, Sandy Clay, Clayey Sand, Sandy Shale and Shaly Sand facies was defined. Chemicals/ Associated minerals present at different depth are Iron oxide, Carbonate, Mica, Pyrite, Coal and Glauconite. Eleven (11) probable reservoir rocks and twelve (12) probable source rocks were identified in the well with the source rocks acting as stratigraphic traps to the probable reservoir rocks.
