INTEGRATED PETROPHYSICAL EVALUATION OF TURBIDITIC SANDS IN NIGER DELTA BASIN

INTEGRATED PETROPHYSICAL EVALUATION OF TURBIDITIC SANDS IN NIGER DELTA BASIN

Abstract:
The Niger Delta Basin is renowned for its significant hydrocarbon reserves, predominantly hosted within turbiditic sandstone reservoirs. Accurate characterization and evaluation of these reservoirs are crucial for effective exploration and production activities. This study presents an integrated petrophysical evaluation of turbiditic sands in the Niger Delta Basin, employing a comprehensive approach that combines various petrophysical techniques and data sources.

The evaluation begins with a detailed review of well logs, core samples, and geological data from selected wells within the study area. Petrophysical parameters, such as porosity, permeability, and water saturation, are derived from well logs using appropriate equations and models. Special attention is given to the challenges associated with the complex lithology, high clay content, and fluid heterogeneity commonly encountered in turbiditic sand reservoirs.

Core analysis data, including plug measurements and laboratory analysis results, are incorporated to validate and calibrate the petrophysical models. The integration of core data helps to improve the accuracy of the petrophysical interpretation and provides valuable insights into the reservoir properties and fluid behavior.

In addition to conventional well log data, advanced petrophysical techniques, such as nuclear magnetic resonance (NMR) and formation pressure testing, are employed to obtain additional reservoir characterization parameters. NMR measurements provide detailed information about pore size distribution, fluid types, and their interactions, while formation pressure testing helps in determining formation pressure profiles and identifying potential fluid contacts.

The integrated petrophysical evaluation is complemented by geological and geophysical data, including seismic interpretation and reservoir modeling. Seismic data aid in identifying structural features, delineating the reservoir geometry, and estimating the extent of sand distribution. Reservoir modeling techniques, such as geostatistics and reservoir simulation, are utilized to create a three-dimensional representation of the turbiditic reservoirs, enabling a better understanding of the reservoir architecture, connectivity, and fluid flow behavior.

The results of this integrated petrophysical evaluation provide a comprehensive understanding of the turbiditic sandstone reservoirs in the Niger Delta Basin. The derived petrophysical parameters and reservoir models serve as valuable inputs for reservoir characterization, reservoir simulation, and field development planning. Ultimately, this study contributes to the optimization of exploration and production strategies, leading to improved hydrocarbon recovery and economic viability in the Niger Delta Basin.
