Comparative Study ofthe Selected Basement Discoveries around the World with Special Emphasis to Anding Utara of Peninsular Malay Basin

A technical comparison of the selected basements discoveries have been made based on geology, geochemistry, reservoir characteristics and production behavior of selected basement reservoirs to find an analog to Anding Utara Field. Anding Utara, a fractured basement discovery in the Peninsular Mal...
