The aim of this paper is to subdivide the sequences within the depth intervals of the five wells in XY-1 Field, offshore western Niger Delta into biozones and correlate the wells. The micropaleontological standard for preparation of foraminiferal samples was employed. A total of 550 ditch cutting samples from five wells were analyzed for benthic foraminifera. The benthic foraminiferal assemblages identified were used for biostratigraphic interpretation. Two major benthic foraminiferal biozones were recognized and they are Spirosigmoilina oligoceanica and Florilus ex. gr. N. costiferum Zones. These biozones are indicative of Middle to Late Miocene age for the wells depth intervals. The biozones erected and their use in well correlation is helpful in deepening the knowledge and development of the offshore western Niger Delta area of Nigeria.
