TDI-Brooks Int'l, in collaboration with AOA Geophysics, has
conducted a number of high profile
marine surveys (hazard, bathymetry, shallow 2-D seismic,
etc) since 2004. TDI-Brooks' research vessels, the R/V
JW POWELL and R/V
GEOEXPLORER, have been utilized for these surveys.
Geometrics
48 Channel GeoEel Digital Streamer System On JW Powell
Additionally, the R/V JW POWELL has installed an advanced
Geometrics 48 channel GeoEel digital streamer system.
The GeoEel system is a lightweight fully digital marine
seismic streamer system designed for application to a wide
range of surveys, including oil and gas exploration, gas
hydrates surveys and a variety of special engineering surveys.
In addition to towed streamer seismic applications, the
GeoEel is also suitable for use as a bay cable in shallow
water transition zone regions.
Sodera
Mini GI Air Gun and GeoEel Digital Streamer
The GeoEel streamer and on-board data acquisition system
is very portable and easy to mobilize for installation on
small shallow draft survey vessels for operation in shallow
water less than 10 meters, or on larger reel equipped deep
water vessels. The acquisition system can be configured
for use with almost any type of marine impulsive source.
The R/V Powell is currently equipped with the Sodera Mini
GI Air Gun (60 cu in), and a high pressure 3,000 psi Price
Compressor. Both single source and multi-source arrays can
be deployed for a variety of seismic data requirements.
Data
acquired from JW Powell using Geometrics 48 channel GeoEel
digital streamer system (600 meters active length), and
a 60 cu in GI Mini Gun. To achieve a rapid shot repetition
rate and uniform gun pressure, the Price W-5 3,000 psi air
compressor system was used, operating at 2,250 psi minimum.
