Seismic and Petrophysical Analysis of Tomboy Field: Identifying Hydrocarbon Reserves in Niger Delta

Abstract

The Tomboy Field in the Niger Delta Basin is thoroughly examined in this article, with an emphasis on petrophysical research and seismic interpretation to pinpoint hydrocarbon reserves. To assess the field's reservoir potential, the analysis combines well log data, 3D seismic scans, and petrophysical characteristics like porosity, water saturation, and Net-To-Gross (NTG).

 Six distinct reservoirs were delineated, each displaying varying hydrocarbon saturation levels, with Reservoirs 5 and 6 showing significant oil accumulations. The study highlights how crucial contemporary 3D seismic interpretation methods are for minimizing reservoir characterization uncertainty and maximizing field development.

Additionally, the application of Petrel software for stratigraphic and structural mapping allowed for the identification of potential drilling locations, with synthetic seismograms used to correlate well logs to seismic data. The results suggest the Tomboy Field contains untapped hydrocarbon potential, particularly in Reservoirs 5 and 6, which are recommended for further exploration and development. The results provide useful insights into optimizing hydrocarbon recovery through integrated seismic and petrophysical analysis and further our understanding of the geology of the Niger Delta Basin.
