The Environmental Deposition of Some Elements Enrichment Using Ditch Cuttings Samples From X – Well in Oliogo, Onshore Niger Delta
Ditch cuttings were collected at various intervals from X well in onshore Niger Delta. The study area which is Oliogo community Delta State Nigeria is located in North – North East (NNE) of Umutu. The purpose of the study is to evaluate the elemental concentration and determine the environment as well as the prevailing conditions under which the elements were deposited. The elemental concentration was determined with Atomic Absorption Spectrometer (AAS) model 969 unicam series. From the lithos tratigraphic study of the selected interval, two lithologic types were determined which are sandy shale and shale. Studies on the geochemical concentration of some elements and their variations with depth show various levels of elemental enrichment in the following order of relative abundance>Na>Ca>Fe>Mg>Mn> Ni>Co>Pb. The degrees of enrichment suggest a significant difference in depositional environment during accumulation. Further studies on the paleo redox proxies of the samples suggest a high oxygen (oxic) environment.
