2 Introduction
The Bonga field is located in the Niger Delta region offshore Nigeria (Fig 1a), First discovered by Shell Nigeria Exploration and Producing Company Limited (SNEPCO) about 20 years ago when a wildcat well was drilled some 120km off the coast of the Niger Delta in water depths of about 800-1200m, it is the first deepwater oil and gas field in Nigeria which was initially explored by Shell on OPL 212 and now operated on behalf of the Nigerian National Petroleum Corporation (NNPC) by Shell in partnership with Exxon, Agip and ELF on block OML 118 (Fig 1b), it covers an area of about 60Km2.

3 Exploration History
First license for offshore deepwater prospecting in the Bonga field was issued to Shell Nigeria in 1993 by which they acquired a 3D seismic data covering an area of 1814Km2 and by 1995 the Bonga-1 discovery well was spudded. Upper to Middle Miocene…
