Title

Adaptive least-squares RTM: inversion based imaging toward true reflectivity

Speaker

Dr. Chong Zeng

Bio

Chong Zeng is a Senior Research Geophysicist at the TGS-NOPEC Geophysical Company, headquartered in Houston, Texas. He earned his B.S. and M.S. in Applied Geophysics from the China University of Geosciences, Wuhan. He received his Ph.D. in Geology with emphasis in Geophysics from the University of Kansas. Chong started his career in seismic industry with BGP International Inc. based in Houston, TX in 2011. He was the primary researcher and developer for full waveform inversion at the Houston Research Center of BGP, China National Petroleum. Currently Chong is the Team Leader in TGS R&D focusing on least-squares RTM. He is interested in various leading-edge seismic imaging technologies for oil and gas exploration. He is also specialized in near surface geophysical methods including surface wave studies and high-resolution seismic exploration with applications to environmental and engineering problems.

Chong has authored and coauthored over 20 technical papers on peer-refereed journals with international circulation. He is a member of the Society of Exploration Geophysics and constantly serves the society as technical reviewers for both journals and conferences. He was the chairman of oral session for seismic modeling during the 82nd SEG international meeting. Chong is also an Associate Editor of Journal of Applied Geophysics and a Guest Associate Editor of Interpretation.

Abstract

Least-squares reverse time migration (LSRTM) refines seismic image toward true reflectivity via iterative geophysical inversion. Compared to conventional depth migration algorithms, LSRTM generates superior seismic images with the advantages including balanced amplitudes, less migration artifacts, higher spatial resolution, and improved images for steep dips and complex structures. LSRTM is implemented with two objectives using different workflows: one is to produce a broadband image with higher resolution, and the second is to improve poorly illuminated areas. The first objective is usually focused on areas of interest in shallower zones, and the second objective would be focused on deeper zones, such as subsalt. In the broadband implementation, LSRTM integrates the advantages of both one-way wave equation migration (WEM) and two-way RTM methods to produce high resolution depth images with enriched low frequencies as well as high frequencies. The final output image contains not only high-frequency and high-resolution horizons but also clear complex structures with sharp geologic boundaries. The image quality is significantly improved compared to that of either conventional RTM or high-frequency WEM. For the application focusing on subsalt enhancements, adaptive strategies are applied to speed up the convergence and address the practical issues such as imperfect migration velocity. It helps improve the image coherency of subsalt horizons by enhancing the weak signals, and clarify event termination of sediments toward salt boundaries by reducing the halo artifacts.

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 http://www.deepwaternola.org

Scholarships

Download an SGS Scholarship Application form to apply. Scholarships are made possible by corporate donations and member sponsorship of our Golf Tournament Fundraiser held in the Spring.

Don't forget scholarship applications are due April 30th! As a reminder, children and grandchildren of all current SGS members that are entering college or currently attending college or graduate school can apply for an SGS scholarship - regardless of their child/grandchild's major!

Applications are reviewed and awarded by the SGS Scholarship Committee based on academic achievement, community service and/or employment history, extracurricular activities, and financial need. Applications will not be considered unless the required transcripts and letters of recommendation are received by the Committee by the deadline. The form and supporting documents must be received by the Scholarship Committee by April 30th. Note - It is also the responsibility of the SGS sponsor to keep their membership current. If you are an SGS member sponsoring a scholarship applicant, but are unsure if your membership is current, please contact Pamela Bucher (Pamela.Bucher@shell.com) to determine your membership status.

Scholarship Application Process:
1. Ensure your SGS membership is current and that your child/grandchild meets the eligibility requirements (see below)
2. Complete the scholarship application form
3. Gather the required supporting documents (a list of the required documents for each educational level is provided in Section Two on the attached scholarship application form).
4. Deliver the application form and supporting documents to a member of the Scholarship Committee via hand delivery, email or mail-in. The 2015-2016 SGS Scholarship Committee Members are:
Robin Broussard, Current SGS President (robin.broussard@shell.com)

2016 ANNUAL SCHOLARSHIP FUNDRAISING GOLF TOURNAMENT & CRAWFISH BOIL

The Southeastern Geophysical Society proudly announce that the 2016 ANNUAL SCHOLARSHIP FUNDRAISING GOLF TOURNAMENT & CRAWFISH BOIL will be held on March 24th (Thursday) at Tchefuncta Country Club, 2 Country Club Park, Covington, LA with an 8:30 AM Shotgun Start.

Each year, SGS awards scholarships to high school seniors and college students majoring in the earth sciences, and our spring golf tournament is the primary source of scholarship funding. These scholarships are an important contribution to the promotion of scholastic excellence, and your participation in the golf tournament will support this worthy cause. This year, we are providing donation options for both organizations and individual members.

If you are unable to participate in the SGS Fundraising Golf Tournament, but would like to donate personally to the Scholarship Fund, you can do so by check, cash or online payment via credit card. To donate funds to the SGS Scholarship Fund online, click the donate button below:

The funds raised are allocated by the Scholarship Committee to High School and University Students and awarded at our luncheon in May.

A big thank you as always to all our sponsors.

Membership

Our membership runs from June 1st one year to May 31st the next. The current membership form can be downloaded here: 2016-17 SGS Membership Application Form. If you played in the Golf Tournament this year you become a member through May 2016. If you didn't then you will need to send in or bring your $25 with next year's application form filled out to one of our events.

SGS membership renewal requests will soon be emailed by the 2016-2017 SGS Secretary to individuals with expired memberships in August. If you do not receive one, then your membership is probably up-to-date.
