STRUCTURAL INTERPRETATION AND HYDROCARBON PROSPECT IDENTIFICATION

ABSTRACT

A comprehensive approach utilizing seismic data was implemented to conduct subsurface mapping in the IBARAKI field of the Niger Delta basin. It has an Area of 355,656.25 km². The primary objective of this study was to create a subsurface map, identify structural characteristics below the surface for potential hydrocarbon reservoirs, and forecast prospects. The methods applied encompassed the analysis of 3D seismic data using Petrel software. Faults and horizons were deduced from the seismic data to generate structural maps, which revealed various structural patterns in the surveyed area, along with amplitude extraction. A specific horizon was charted, and multiple faults were mapped to facilitate 3D subsurface structural interpretation. These elements were instrumental in producing time structure maps through the Petrel Interpretation tool. The findings indicate that the field's trapping mechanisms are conducive to the accumulation of hydrocarbons. Zones A of area 1.240x10^8 ft², B of 11.44x10^7 ft² and C of 1.97x10^7 ft² emerge as having the most promising potential prospects. Two principal structural trapping mechanisms identified are the rollover anticline and the simple anticline. This study underscores the significance of seismic structural interpretation in the development of subsurface reservoir maps, comprehension of structural variations, and amplitude extraction for prospect assessment.
