3-D, AVO, and poststack multiattribute analysis have been used successfully to define the internal character of a gas sandstone reservoir in Banuwati Field, offshore Sumatra. The field produces from Early Miocene “A” and “B” sandstones of the Upper Gita member, Talang Akar Formation, at a depth of 5500 ft. The range of reservoir channel sandstone thickness is 20–70 ft; the gas column is as tall as 200 ft. The main data set is the 1993 “3-D Gas Area” survey—280 km2 of 3-D prestack time-migrated seismic data.
A fieldwide structural and stratigraphic analysis was begun in 1998 to more accurately...
