Integrated Petrophysical Analysis of D1000 and E2000 Reservoirs in Niger Delta Basin

Abstract

The Niger Delta basin is home to the D1000 and E2000 reservoirs, identified through a well log investigation of four wells. Lithological variations were discerned via gamma ray logs, distinguishing pure shale and clean sand. Resistivity logs within sand units indicated potential oil presence, complementing the identification of hydrocarbon-bearing intervals. Petrophysical analysis involved calculating key parameters such as Net-to-Gross ratios, porosity, water saturation, and permeability, facilitating volumetric investigations. Volumetric estimates, including Hydrocarbon Pore Volume (HCPV) and Stock Tank Oil Initially in Place (STOIIP), highlighted significant hydrocarbon potential in the reservoirs. The integration of well log data underscored the substantial hydrocarbon reserves present in the D1000 and E2000 reservoirs. Their high porosity and permeability suggest favourable conditions for hydrocarbon extraction, supporting the economic viability of the region. This comprehensive approach enhances understanding of reservoir characteristics, vital for successful exploration and development endeavours.
