چکیده    The cretaceous sediments in the anambra basin (se nigeria) consist of a cyclic succession of coals, carbonaceous shales, silty shales and siltstones interpreted as deltaic deposits. the objective of this study is to compare the hydrocarbon generation potential of organic matter from shale sediments along isugwuato-okigwe axis in the anambra basin, nigeria. data obtained indicates the presence of type iii kerogen with tmax values are between 424 and 441ºc indicating that the shales are thermally immature to marginally mature with respect to petroleum generation. hydrogen index (hi) values range from 14 to 388.9mghc/gtoc while s_1 + s_2 yields values ranging from 0.2 to 1.0mghc/g rock, suggesting that the shale have gas generating potential. the toc values ranges from 1.3 to 3.0%, an indication of a good source rock of terrestrially derived organic matter. the high oxygen index (oi) (16.3 mgco_2g-1toc), ts (1.35) and toc/ts (1.5) suggest deposition in a shallow marine environment. based on the kerogen type, shales from the studied area will equally generate oil and gas if its organic matter attained sufficient thermal temperature.
