 en Petrophysical Charaterization of the Kwale Field Reservoir Sands (OML 60) from Wire-line Logs, Niger Delta, Nigeria
Ekine, A. S. & Iyabe, Paul


Well log data from the deep parts of the six wells located in the Kwale field of the Niger delta basin (OML 60) were used in the determination of some Petrophysical characteristics of the reservoir sands. Well log data were obtained from sonic, gamma-ray, matrix density and resistivity logs. The petrophysical characteristics investigated were porosity, water saturation and permeability. The results of the analysis revealed the presence of twelve sand units. Correlation of these sand bodies indicate that the reservoirs consist of stacked barrier bar and point-bar sandstones. The thickness of each sand unit is highly variable, ranging between 5.0 and 95.0 m. Average shale-corrected porosities vary between 11.0 and 19.0 percent and generally decreasing with depth. The average water saturation of these units vary between 52.5 and 88.5 percent. These values are generally high for the sand units in wells 2, 5, 6 and 8. Similarly, the average permeability values vary between 3.2 and 28.0 mD. This study is a first attempt to make available Petrophysical data for the reservoir sands in the Kwale field of the Niger delta basin. The results of this study will also enhance the proper characterization of the reservoir sands. However, other sources of confirmative and collaborative investigations will therefore be essential and consequently will be the focus of another study @ JASEM
