Abstract


The aim of the study is to identify and record the taxonomic notes on marker benthic foraminifera in the study area. The area of study is located in the Tomboy field of the offshore western Niger Delta area of Nigeria. In all, 550 ditch cuttings samples were retrieved at 18.29 meter intervals from the five wells studied (TMB-1, TMB-2, TMB-4, TMB-5 and TMB-6), respectively. The standard micropaleontological preparation technique for foraminiferal samples was employed. The benthic foraminifera were categorized into two groups, namely: benthic calcareous and benthic arenaceous/agglutinated foraminifera, respectively. TMB-1 well contained 1,188 calcareous benthic and 224 arenaceous benthic specimens, while 739 calcareous benthic specimens and 180 arenaceous benthic specimens were identified in TMB-2 well. On the other hand, 1,171, 1,099 and 1,325 calcareous benthic specimens and 250, 244 and 257 arenaceous benthic specimens were identified and counted in TMB-4, TMB-5 and TMB-6 wells, respectively. Total of thirty-five species were identified from the population distribution in the five wells and their taxonomic notes were properly recorded accordingly.
