ABSTRACT
A suite of four well log located at the OSEYE field, Niger Delta were analyzed with Petrel software for Petro-physical evaluation. The methods adopted involves petro-physical analysis and reservoir classification. Detailed petro-physical analysis revealed various reservoirs but two reservoirs were analysed. Average reservoir parameters such as porosity (0.27), gross thickness (68ft), hydrocarbon saturation (0.64) permeability (2212.8mD) and netgross (0.80) were derived from the petrophysical analysis. The analysis of the all the well sections revealed that each of the sand units extends through the field and varies in thickness with some unit occurring at greater depth than their adjacent unit that is possibly an evidence of faulting. The shale layers were observed to increase with depth along with a corresponding decrease in sand layers. From the analysis, particularly the resistivity log, the two delineated reservoirs were identified as hydrocarbon bearing units across two wells (Well 2 & Well 6) in the OSeye field.
