Enhancing Our View of the Reservoir: New Insights Into Deepwater Gulf of Mexico Fields Using Frequency Decomposition


Michael Murat, Chevron, Covington, Louisiana


Color-blended frequency decomposition is a seismic attribute that can be used to deduce or draw out and visualize geomorphological features enabling a better understanding of reservoir architecture and connectivity for both exploration and field development planning.

Color-blended frequency decomposition was applied to seismic data in several areas of interest in the Deepwater Gulf of Mexico. The objective was stratigraphic characterization to better define reservoir extent, highlight depositional features, identify thicker reservoir zones and examine potential connectivity issues due to stratigraphic variability.

Frequency decomposition is a technique to analyze changes in seismic frequency caused by changes in the reservoir thickness, lithology and fluid content. This technique decomposes or separates the seismic frequency spectra into discrete bands of frequency limited seismic data using digital filters. The workflow consists of frequency (spectral) decomposition, RGB color blending of three frequency slices, and horizon or stratal slicing of the color blended frequency data for interpretation.

Patterns were visualized and identified in the data that were not obvious on standard stacked seismic sections. These seismic patterns were interpreted and compared to known geomorphological patterns and their environment of deposition. From this we inferred the distribution of potential reservoir sand versus non-reservoir shale and even finer scale details such as the overall direction of the sediment transport and relative thickness.

In exploratory areas, stratigraphic characterization from spectral decomposition is used for prospect risking and well planning. Where well control exists, we can validate the seismic observations and our interpretation and use the stratigraphic/geomorphological information to better inform decisions on the need for and placement of development wells.


Michael Murat is a Geophysical Consultant with the Gulf of Mexico Applied Reservoir Management Geophysics team at Chevron North America Exploration and Production Company. He has 26 years with Chevron working on reservoir properties from seismic, AVO, DHI risking and 4-D time lapse analysis. Michael holds a M.S. degree in Geophysics from Indiana University and was a Fulbright Fellow Warsaw University and Polish Academy of Sciences, 1988-1989. He also holds a BS degree in Geophysics from Saint Louis University.


Automated Fault Interpretation and Extraction using Improved Supplementary Seismic Datasets


Trevor Bollmann, Chevron, Covington, Louisiana


During the interpretation of seismic volumes, it is necessary to interpret faults along with horizons of interest. With the improvement of technology, the interpretation of faults can be expedited with the aid of different algorithms that create supplementary seismic attributes, such as semblance and coherency. These products highlight discontinuities, but still need a large amount of human interaction to interpret faults and are plagued by noise and stratigraphic discontinuities. Hale (2013) presents a method to improve on these datasets by creating what is referred to as a Fault Likelihood volume. In general, these volumes contain less noise and do not emphasize stratigraphic features. Instead, planar features within a specified strike and dip range are highlighted. Once a satisfactory Fault Likelihood Volume is created, extraction of fault surfaces is much easier. The extracted fault surfaces are then exported to interpretation software for QC. Numerous software packages have implemented this methodology with varying results. After investigating these platforms, we developed a preferred Automated Fault Interpretation workflow.


Trevor Bollmann is a Technical Geophysicist with the Gulf of Mexico Applied Reservoir Management Geophysics team, Chevron North America Exploration and Production. He has 2.5 years with Chevron working on reservoir properties from seismic, AVO, and seismic inversions and supplementary volume creation. Trevor has previous experience with tomographic inversion of teleseismic body waves. He holds a M.S. degree in Earth and Planetary Sciences from Northwestern University and a B.S. degree in Geology and Geophysics from Missouri University of Science and Technology.


Energy Day returns to the museum with major oil industry hands on display stations.

We are looking for enthusiastic volunteers to cover shifts of 11am-1pm and 1pm-3pm.

The SGS booth will have our geophone and oscilloscope so the kids can see how we can turn something they can hear and feel (banging/vibrations on the table) into something they can see on the screen. Lisa will bring her iPad to show the seismograh app to show movement in the X, Y, & Z directions. There will also be a non-working hydrophone on display and a wooden fault block model.

Other booths will have the ever popular oil finder game, how an oil field forms form, properties of oil, and some other events in the works.

We are also looking to open the event up for a refinery display, Entergy, Solar, Wind, and NASA to potentially contribute.

SGS and NOGS have a great working relationship at outreach events. Our displays are set up so that the kids and families can progress from station to station and see what geologists and geophysicists do and how it all fits together.

If you would like to volunteer for a time slot at the SGS booth, please contact:

Lisa Kennedy
cell: 504-782-7100 (call or text) (personal) (work)


This fall NOGS is very active with 3 large scale oil industry outreach science career events.

Please consider volunteering for one or more of these fun filled geology learning opportunities.

Also consider attending the 47th New Orleans Gem, Mineral, Fossil, and Jewelry Show for some excellent specimens.

Energy Day Sept 16th
Louisiana Children’s Museum 11-3
Stem Education Day Sept 30th
Saints Training Center South End Zone 10-2
New Orleans Gem and Mineral Show Oct 13-15
Alario Center, Westwego weekend attraction

August 18th, 19th & 20th 2015

Hilton Riverside New Orleans

Geoscience Opening Seminar, August 18

“The Temporal and Spatial Evolution of Reservoirs and Traps, Northern Deep Water Gulf of Mexico” with Paul Weimer, University of Colorado

This course will summarize the temporal and spatial evolution of the reservoirs for the 220 fields in the northern Deepwater Gulf of Mexico. Lectures and exercises will address the key components of each of the major reservoirs by age. The trap types for all of the fields are reviewed and placed within their regional context and exploration province type.

Tickets for the Geoscience Seminar are $225.00 and can be purchased along with your DWTS registration at
