W-7: Subsea Technologies and Seafloor Property Characterization

SEG 2012 Annual Meeting Technical Program

Date: Thursday, 8 November 2012
Time: 1:30 pm – 5:00 pm
Location: Mandalay Bay Convention Center, Room: Breakers F
Organizers: Hugues Djikpesse and Kelly Wrobel   
Through the support of the SEG Research Committee

Description

The workshop is designed for professionals and students in the oil and gas industry and in academia who are interested in subsea technologies in general, and in seafloor characterization in particular. The goal of this workshop is to create a discussion forum for sharing experiences in acquisition, processing and applications of geotechnical and geophysical measurements for seafloor properties characterization.

This includes:

• To help geophysicists in better understanding geotechnical seafloor measurements, e.g., when and how they are collected as well as their actual field applications
• To help geotechnical specialists in better understanding geophysical seafloor measurements, how they are derived, and their importance for accurate seismic waveform modeling and inversion
• To discuss technology and application trends, and how the geophysical community can participate in the fast-growing market of subsea operations in the oil and gas industry

The format of the workshop is as follows. A keynote lecture will introduce the problems under consideration and review actual practices. Several guest speakers will discuss how subsea technologies fit into their exploration, drilling and surveillance strategies, and more specifically, how seafloor properties are characterized in their organization, and what they are used for. The workshop will end with a panel discussion including experts from O&G operators, service companies and academia.
