Solving Interpretation Problems using Machine Learning on Multi-Attribute, Sample-Based Seismic Data

Multi-Seismic attribute analysis is an unsupervised learning process in which clusters of data points are identified by similar properties. This form of Machine Learning not only uses numerous seismic attributes, but in doing so, often reveals details in the data not previously identified by the interpreter. Rather than classifying data based on wavelet information, more discrete lithologic patterns can be defined using sample statistics from the attributes.  The result of this sample-based statistical analysis is that one can interpret thin-bed resolution well below conventional wavelet tuning.  This, in turn, helps with very accurate reservoir prediction when tying into existing production or in the estimation of new reserve potential in exploration plays.

This presentation will show several case histories taken from interpretive work along the onshore Gulf Coast Basin and the results of the neural analysis of multiple seismic attributes to help find hydrocarbons and determine reservoir extents.  The key to using multiple seismic attributes and statistically analyzing them using data points from each sample is that one can now “interpret” depositional information on a much finer scale than ever before and even correlate details in the classified volume to log curves. This is something that interpreters have been trying to do for decades.


Deborah Sacrey is a geologist/geophysicist with 41 years of oil and gas exploration experience in the Texas, Louisiana Gulf Coast, and Mid-Continent areas of the US. Deborah specializes in 2D and 3D interpretation for clients in the US and internationally.

She received her degree in Geology from the University of Oklahoma in 1976 and began her career with Gulf Oil in Oklahoma City. She started Auburn Energy in 1990 and built her first geophysical workstation using the Kingdom software in 1996. Deborah then worked closely with SMT (now part of IHS) for 18 years developing and testing Kingdom. For the past eight years, she has been part of a team to study and bring the power of multi-attribute neural analysis of seismic data to the geoscience community, guided by Dr. Tom Smith, founder of SMT. Deborah has become an expert in the use of the Paradise® software and has over five discoveries for clients using the technology.

Deborah is very active in the geological community. She is past national President of SIPES (Society of Independent Professional Earth Scientists), past President of the Division of Professional Affairs of AAPG (American Association of Petroleum Geologists), Past Treasurer of AAPG and Past President of the Houston Geological Society. She is currently the incoming President of the Gulf Coast Association of Geological Societies (GCAGS) and is a member of the GCAGS representation on the AAPG Advisory Council. Deborah is also a DPA Certified Petroleum Geologist #4014 and DPA Certified Petroleum Geophysicist #2. She is active in the Houston Geological Society, South Texas Geological Society and the Oklahoma City Geological Society (OCGS).
