Abstract
This poster presents the application of the pulsed neutron capture and carbon/oxygen logs in identifying remaining hydrocarbon saturation for infill drilling opportunities in a mature Malay basin field located in offshore Malaysia. Key challenges faced during data acquisition and analysis under complex borehole and reservoir environment settings are discussed. These challenges include the small capture cross section contrast between oil and water when traversing an oil-water contact and the reduced dynamic range of the carbon/oxygen ratio response in larger completions. A brief review of the tool measurement principles, operational considerations and limitations, interpretation principles, and integration of engineering and geological data will also be presented together with several key learnings from the case studies.
