ABSTRACT
This palynofacie analysis was conducted on ditch-cutting samples of the Imo Formation from Egboha Well. Thirty-four (34) ditch cutting samples were collected at an interval of 0-20ft – 330-340ft covering a thickness of 340ft for palynofacies analysis. The lithologic section comprises sand-shale sequence.
This is a multidisciplinary approach to the study of some selected samples from the Imo Formation, supported by the degree of effervescence from acid test on the samples, nature of organic matter, kerogen and organic facies type, paleoxygenation, paleosalinity, environment of deposition and organic geochemistry (total organic carbon-TOC). The palynofacies analysis provides evidences that the nature of the organic matter preserved in the samples are of terrestrial origin. The abundance of phytoclasts and TOC data confirms Type III/IV kerogen and organic facies C and CD in the Imo Formation. Intermediate salinity (palosalinity is of brackish water) and oxic conditions were prevalent during the time of deposition (paleosalinity and paleoxygenation). From the aforementioned above, a nearshore environment (marginal marine) was deducted to be the prevailing environment at the time of deposition.
