Anticlinal Structure of the Reservoir Characterization and Formation Evaluation of a “Cobalt Field”, Southern Niger Delta Using Well Log Data

Six wells Cobalt-1, Cobalt-2, Cobalt-3, Cobalt-4, Cobalt-5 and Cobalt-6 were investigated on the cobalt’s field of the Niger Delta. A detailed petrophysical analysis on all the wells were carried out using SchlumbergeTechlog software of well log data in order to determine their petrophysical parameters. Quantitative and qualitative petrophysical data interpretations were employed in the analysis. Five reservoir sand bodies were delineated for each well and well two was interpreted as water. Reservoir thickness varies from 7 – 120 m. The reservoir rock properties were interpreted as a good quality reservoir rock which has been established from high average porosity (19 – 32 %). Hydrocarbon saturation zones varies in terms of quality reservoir are detected through intervals having Sw <60 %. Cobalt’s field in the Niger Delta contains adequate amounts of hydrocarbon accumulation.
