2014 SEG/DGS Workshop

Near-Surface Modeling and Imaging

8-9 March 2014
InterContinental Regency Hotel
Manama, Bahrain

Call for Abstracts now open!

New large structural traps for hydrocarbons are rare. The trend is for low relief structures in depth and time imaging. The imaging of stratigraphic traps is now also very important. These both require near-surface models of greater accuracy and fidelity. Innovative characterization of the near surface rather than compensation for the near-surface appears a key concept for advancing optimal high resolution imaging of smaller and deeper exploration targets. This workshop will focus on advances in characterizing modeling the near-surface and imaging with near surface models. The twin challenges of improving accuracy and the integration of models and methods will be explored. Discussions will center on finding answers to the following questions:

• Which approach can delineate velocity inversions?
• How can we use surface wave inversion for P-Wave imaging?
• Can multiple suppression be improved using more accurate near-surface model?
• What are the limitations of travel time tomography?
• Is the effect of near-surface impacting passive seismic?
• Should we include anisotropy and attenuation into near-surface modeling?
• How far non-seismic methods help to improve the near-surface model?
• How does changes in the near-surface model affect time lapse seismic?
• Should we do depth imaging with near-surface models?
• How can we mitigate the cycle skipping problem?
• What are the acquisition requirements (wavefield sampling) to improve near-surface modeling?
• How can we capture and use shallow reflections?
• Seismic interferometry: a tool to eliminate or to improve near-surface modeling?
• Can FWI improve near-surface modeling?
• What are the optimal workflows to utilize near-surface models for improving the imaging of deep exploration targets?
• Are more accurate near-surface models needed for unconventional exploration?

This workshop is open for contributions in all subjects related to near-surface characterization which may include:

• Challenging case histories                       
• Seismic methods (refraction and tomography, etc.)
• Non-seismic methods        
• Surface wave inversion     
• Extreme gradients and velocity inversion
• Joint inversion of seismic and non-seismic data          
• Dynamic corrections, Datuming and imaging
• Time vs. depth imaging
• Emerging technologies (FWI, interferometry, passive seismic, etc.)
• Remote sensing
• Refraction and reflection tomography: bridging the gap between shallow and deep

Visa Information and Invitation Letter

Participants in the SEG/DGS Workshop on Near-Surface Modeling and Imaging may generate an official invitation letter by clicking on Create my letter below. Fill in the blanks on the form and it will generate a letter which you can print and use in obtaining a visa.

For those whose company or organization is planning on sending more than one individual to the workshop, additional documentation may be required for scheduling an appointment with the local American Embassy. If additional assistance is required, fill out a separate invitation letter for each individual requesting a visa using the form below. Each invitation letter has a unique reference number. Produce one cover letter listing all individuals requesting a visa. The letter must include the following information for each individual:

• Name
• Passport number
• Date and place of birth
• Nationality as it appears on the passport
• Reference number from the invitation letter

Fax these forms together with the cover letter printed on the group's official stationery to +1.918.497.5557, Attention: Visa Letter Assistance.

Please note that this letter does not guarantee that you will be granted a visa, nor does it commit SEG to pay any expenses you may incur. It is the sole responsibility of the attendee to obtain the necessary paperwork for entry to Bahrain.
