Abstract
The process of statistically analyzing multiple attributes using a SOM (Self-Organized Map) algorithm has been around for several decades. However, advances in computing power, coupled with the many new attributes developed in the last 30 years, has made this type of analysis extremely powerful, especially in using seismic data.
In the past, SOM as been used on only one attribute at a time using the seismic wavelet as the basis for the neural/cluster analysis. The approach in this presentation is using SOM on multiple seismic attributes at one time, and in a sample-based, not wavelet, format. This type of cluster analysis/pattern recognition allows the user to understand much finer detail in the sub-surface and delineate stratigraphic information well below conventional tuning thicknesses. Petrophysical information is used to show pay zones and the use of geobodies will determine potential reserves. The use of probability statistics in this case can show depletion in the field.
This presentation is an analysis of the seismic data around Double A Wells Field in Polk County, Texas and through Bi-Variate Statistical Analysis show how the neural clusters are associated with pay in the field and then determine if there are any locations left to drill and what the potential reserves might be in those locations.
Biography
Deborah is a geologist/geophysicist with 48 years of oil and gas exploration experience in Texas, Louisiana Gulf Coast and Mid-Continent areas of the US, and internationally she has worked in Australia, Tunisia, Gulf of Thailand, Turkey, Hungary, Germany and Columbia.. She received her degree in Geology from the University of Oklahoma in 1976 and immediately started working for Gulf Oil in their Oklahoma City offices.
She started her own company, Auburn Energy, in 1990 and built her first geophysical workstation using Kingdom software in 1996. She helped SMT/IHS for 18 years in developing and testing the Kingdom Software. She specializes in 2D and 3D interpretation for clients in the US and internationally.
For the past 14 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 public, guided by Dr. Tom Smith, founder of SMT. She has become an expert in the use of Paradise software and has had many discoveries for clients using multi-attribute neural analysis.
Deborah has been 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 also Past President of the Gulf Coast Association of Geological Societies and has been on the Advisory Council of AAPG twice.. Deborah is also a DPA Certified Petroleum Geologist #4014 and DPA Certified Petroleum Geophysicist #2. She is President of AAPG for the term July 1, to June 30, 2025.
She belongs to AAPG, SIPES, Houston Geological Society, South Texas Geological Society and the Oklahoma City Geological Society (OCGS).
