Hydrocarbon exploration in Odo Field in the Niger Delta Basin Nigeria, using a three-dimensional seismic reflection survey

A three-dimensional seismic reflection survey carried out in Odo Field in the central swamp of the Niger Delta Basin has been interpreted with respect to exploration for hydrocarbons. The Odo Field is marked by a large southwest heading listric growth fault with numerous synthetic and antithetic faults. The two picked seismic events, horizons 1 and 2 indicate four closures each, which are hydrocarbon bearing. The faults in the field thus support hydrocarbon accumulations which are seen to be mainly fault/dip closures. The expectations calculated for the observed fault closures suggest that several in-field appraisal prospects exist. The seismic attributes (amplitude maps) furthermore suggest that horizon 1 is mainly gas bearing.
