[SIO GP Seminars] Friday Seminar: Richard Clarke, 3D OBS survey in the Gulf of Mexico

Munk Conference Room

3:00 PM: Seminar

Richard Clarke, a research scientist from BP, will be speaking about  a 
3D ocean bottom seismic node survey over the Atlantis field, in the 
deepwater Gulf of Mexico.  BP and SIO have been working together to 
fund non-commercial seafloor technology projects; electromagnetic 
methods for hydrocarbon locations, seafloor geodetic networks for 
underwater landslides and tsunami hazards for southern California, AUV 
development: all are higher development engineering projects funded by 
BP that will hopefully produce several Scripps student thesis' and work 
for our own faculty .  In the struggle for research funds and ship 
time, industrial collaborations are becoming increasingly important to 
SIO.

Abstract:
BP recently finished acquiring a large 3D ocean bottom seismic node 
survey
over the Atlantis field, in the deepwater Gulf of Mexico, with water 
depths
from about 1300m-2400m. About 900 four-component nodes were used in 2
patches; a total of 1700 node locations. The nodes were spaced about 
400m
apart and placed and retrieved by remotely operated vehicles.
The speaker will give an overview of the survey and then describe how 
BP is
processing this novel data set, including: the approach to timing, node
positioning, geophone orientation, source side multiple removal, and the
production of images using the PZ summed data (primary reflections) and 
the
PZ difference data (receiver side multiples).

Bio:
Richard has a BA from Cambridge in Engineering, an MSc in Geoscience 
from
Paris VI and a PhD in Geophysics from the University of Pau and the 
French
Petroleum Institute (IFP), working on reflection tomography with 
multiple
arrival travel times. Richard joined Amoco's Tulsa Research Lab in 
1998, and
moved to Houston with BP in 1999. Since then he has worked on seismic
processing and imaging with a focus on multi-component processing.
