Seismic attribute technology for reservoir forecasting and monitoring

摘要

During the 1970s and 1980s, the seismic attributes most used in petroleum exploration were amplitude-based instantaneous attributes. However, in the 1990s, seismic attribute technology has dramatically advanced in several directions; techniques now range from single-trace instantaneous event attribute computations to more complex mul-titrace windowed seismic event attribute extractions to the generation of seismic attribute volumes. Applications run from simple amplitude anomaly detection to monitoring fluid front movement over time. Seismic attribute technology can extract information from seismic data that is otherwise hidden in the data and which will enhance the use and value of geophysics in an area that is now a prime focus of the petroleum industry: predicting, characterizing, and monitoring hydrocarbon reservoirs.
