A case history of the seismic amplitude interpretation for Huffcos oil and gas discoveries at the Nilam and Badak fields inthe Sanga-Sanga PSC Block of East Kalimantan, Indonesia.Huffcos Badak and Nilam fields aregiant gas fields which together currently produce over 1 .O BCF/day from sands within theMiocene age Balikpapan Beds.The reservoir sands were deposited within a thick regressive deltaic sequence that includes coals, shales and occasional limestones. Wells typically encounter multiple stacked pay sands at depths ranging from about 5500 feet to over 13,000 feet.Individual sand thicknesses can vary from several feet to over 200 feet. Rapid lateral stratigraphic variations in sand thickness are the rule, rather than the exception.The seismic amplitude response to these sandstones is interpreted based on an integrated geological and geophysical approach by incorporating the study of well logs, seismic sections, NMO corrected gathers, AVO graphs and theoretical models.
