Geochemical Log Evaluation Procedure of Difficult-to-diagnose Reservoirs

This paper expounds the geochemical log evaluation procedure and its technical limitations, analyzcs the similarities and differences through examples between difficult-to-diagnose reservoirs which include light crude oil, heavy crude oil, low resistivity and fractured reservoirs and other types of reservoirs, and discusses the geochemical log evaluation procedure and the interpretation method of hydrocarbon bearing and water bearing beds.
