Determining the Relationship between Resistivity, Water and Hydrocarbon Saturation of Rock Formation Using Composite Well Logs

Mamudu Afizu

Abstract


This paper focuses on comparing the percentages of water and hydrocarbon saturation to the resistivity of formation of reservoirs in an oil well by using composite logs. The composite logs were obtained from Nigeria National petroleum co-operation (NNPC) Etete Benin branch Edo state. Eight reservoirs were considered from a well in Ambura field in Delta state. When the logs were interpreted a composite table containing values of resistivity, percentages of water and hydrocarbon saturation was produced. From the values obtained it was found that resistivity increases with hydrocarbon saturation and decreases with water saturation in each reservoir. A graph of resistivity against hydrocarbon saturation and resistivity against water saturation was plotted. In conclusion, suggestions and recommendations were made to promote further research work on the project.
