Evaluation of Hydrocarbon-Bearing Reservoir Intervals Using Conventional Well Logs and Crossplot Techniques: A Case Study of Chevrun Field
Abstract
This study evaluates hydrocarbon-bearing reservoir intervals within the Chevrun Field, Niger Delta Basin, using conventional well logs and crossplot techniques for reservoir characterization and hydrocarbon identification. Gamma ray, resistivity, density, and neutron logs from three wells (CHEV_001, CHEV_002, and CHEV_003) were integrated to identify reservoir units and determine key petrophysical parameters. Two major reservoirs, CHEV_1 and CHEV_2, were identified within the Agbada Formation and are characterized by low gamma ray values, elevated resistivity responses, and density–neutron crossover effects indicative of hydrocarbon-bearing sandstone formations. Crossplot analyses revealed low shale volume, moderate to good porosity, and significant hydrocarbon saturation within the reservoirs. The resistivity–porosity relationship further confirmed that highly porous intervals correspond to hydrocarbon-saturated zones. Reservoir thickness analysis showed progressive thickening toward the eastern section of the field, suggesting enhanced reservoir development and improved hydrocarbon storage capacity. The integrated interpretation indicates that the identified reservoirs possess favorable petrophysical properties and significant hydrocarbon potential. The study demonstrates that conventional well logs and crossplot techniques provide an effective approach for reducing uncertainty in reservoir characterization and hydrocarbon prospect evaluation in the Niger Delta Basin.
