Reservoir Characterization for Carbon Dioxide Containment in the Aida Field, Niger Delta

World temperatures have increased from −0.31 °C to 1.17 °C in 2023. The Paris Agreement outlines that global warming should be restricted to 1.5 °C and emissions cut by 45% by 2030 to achieve net zero by 2050. This study aims to assess subsurface formation’s structural integrity and capacity potentials for CO2 storage in the Aida Field Niger Delta. Well logs and 3D seismic data were utilized to characterise reservoir structural configuration and evaluate subsurface properties to generate a static model. Three reservoirs were mapped; G_02, G_10, and H _03 with thicknesses of 105 m, 50.64 m, and 48.4 m respectively. Forty (40) faults were identified; six (6) major faults and thirty four (34) minor faults. Major faults serve as traps for reservoirs bounding Aida 004ST1well. The G_02 reservoir was picked as a target for CO2 because it suited the International Energy Agency parameters. The static model and petrophysical analysis estimated values for the G-02 reservoir; a porosity range of 20–24%, permeability (> 100mD), shale volume > 30%, and carbon dioxide storage capacity of 25.5852 × 106 kgm3. Results indicate the G_02 reservoir is suitable for carbon storage. However, only well logs and 3D seismic data were used in this study. The absence of ditch cuttings, core data, and pressure data prevents key parameters in CCUS from being calculated. We recommended additional data be incorporated to aid in understanding the reservoir stress regimes, pressure threshold, hydrocarbon column height, CO2 height and slip tendency of the faults field. This would eliminate the risks encountered during subsurface gas storage operations.
