The organic geochemical and pore structure characteristics of deltaic shale and coal from Mamu Formation, Anambra Basin, Nigeria were investigated based on Rock-Eval analysis, mineralogy, N2 and CO2 adsorption and scanning electron microscopy (SEM) analyses. The results from the Rock-Eval analysis, elemental composition and carbon isotope of the kerogen, classify the organic matter as mixed Type II/III and III with high TOC contents. The shale and sub-bituminous coal samples would generate both oil and gas. Pore network in the shale samples is typically associated with micropore and mesopore emanating from primary organic matter and mineral pores. The balanced amounts of the clay and quartz minerals are of a great benefit for shale gas exploration and development in the Formation.
