Abstract

The geology of the Niger Delta comprises fault blocks supporting immense hydrocarbon reserves, which require standard exploration methods. This research is concerned with the recovery of hydrocarbons in the XYZ field through seismic attribute (SA) analysis. Attributes such as the amplitude, frequency, and phase analysis of the seismic waves make up SA analysis which serve as coherent indications of the subsurface conditions as well as prospects for hydrocarbon emergence. In this way, benefiting from the suite of software tools, this research interprets seismic data and evaluates petrophysical properties based on incorporated 3D seismic data set and well logs. These are synthetic and antithetic faults and significant growth faults in a southwest-to-northeast orientation. Both the horizon mapping and generation of time and depth surface maps validated the types of used velocities. This proved to have good reservoir thickness, as well as porosity and permeability, which would signify considerable potential for hydrocarbons. Relative acoustic reflectance, predominantly RMS amplitude, contributed significantly to the formulation of hydrocarbon-bearing zones. The findings of the study map the hydrocarbon potential, and besides, offer volumetric estimations of Reservoir A at 240 million STB and Reservoir B at 470 million STB. The findings of this study clearly show that; for hydrocarbon exploration and production in the Niger Delta, advanced seismic attribute analysis is a critical factor.
