Many brownfields have had 4D-seismic technology applied
successfully to optimize reservoir production and recovery.
This paper describes how 4D-seismic results were incorporated
into the geological model and illustrates applications in reservoir-
management decisions, thereby mitigating drilling risks
in Marlim deepwater turbidite heavy-oil field. It highlights the
repositioning of many planned wells and the improvement in
the history match by use of the updated geological model.
The Marlim field is off the eastern Brazilian coast in water
depths varying from 2,000 to 3,600 ft (Fig. 1). The field is the
largest producing oil field in Brazil. Three seismic surveys cover
the Marlim field. The first was acquired in 1986 and the others
in 1997 and 2005. The most recent survey was acquired specifically
for reservoir-characterization and -monitoring purposes.
