ABSTRACT

This project involves the petrophysical evaluation of the Gbesimi Field in the Niger Delta region of Southern Nigeria, employing well log data. Petrophysical evaluation assesses various rock and fluid properties within reservoirs to understand their potential for hydrocarbon production. In this study, well log data will be analyzed to characterize the reservoir rock properties, such as porosity, permeability, and fluid saturation, crucial for estimating hydrocarbon reserves and optimizing production strategies. The findings will contribute to the understanding of the reservoir's geology and aid in reservoir management and development planning in the Gbesimi Field. This study employs aapproach combining well logging data interpretation with petrophysical properties of the reservoir formations using Petrel Software. Various well logs, including gamma ray, resistivity, density, and neutron logs, were used to analyze the reservoir and has a shale volume of about 37.9%; a pay zone thickness of 142.5m, total porosity of 25.8%, effective porosity 25.3% permeability 2005.5mD, hydrocarbon saturation of 92.6%. which signify that Gbesimi-field of the Niger Delta is economically viable, demonstrating substantial hydrocarbonbearing potential.This study underscores the importance of petrophysical evaluation in reservoir characterization and development strategies in the Gbesimi Field and similar hydrocarbon reservoirs.
