Resolving thin stringer sands

摘要

Novel processing techniques help one operator overcoming obstacles related to thin, sub-seismic features in the shallow Gulf of Mexico. In the 1900s it wasn't uncommon to search for oil tucked beneath structurally simple anitclinal traps. However, geoscientists have to work much harder today to discover economic reservoirs. Searching for hard-to-find stratigraphic traps is common as we reexamine mature plays to uncover missed hydrocarbons. These days, simply relying on the full-stack amplitude response as a direct hydrocarbon indicator isn't enough; typically, advanced reservoir characterization techniques and seismic attribute analyses (pre- and post-stack) are needed to evaluate a reservoir properly.
