One of the most important features of the GeoRes Subsea
System is it’s ability to be REMOTELY OPERATED.
The GeoRes SubSea System including high capacity RAID
servers, power supply monitors and network controllable
power strips may be securely and fully controlled remotely
over Ethernet connection. This means that the system can
be configured, tested, maintained, upgraded and operated
completely unmanned. Diagrammed is a basic offshore—

The GeoRes SubSea System is an advanced multi-component ocean bottom seismic recording system featuring
scalable system architecture enabling ten of thousands of channel-count recording capability. The system may
be configured for permanent reservoir monitoring or retrievable acquisition setting new standards for subsea
reservoir characterization and exploration.

GeoRes Imagine HC
The GeoRes Imagine HC (High Capacity) recording

Electro-Fiber Optic
Control Umbilical
High capacity fiber optic data transmission
provides continuous, real-time acquisition
of very large channel-counts over very
long distances. This is particularly important for deep water reservoir monitoring
systems adding a new dimension to realtime, high capacity recording from long
distances.
The digitized 4C sensor module consists of a 4-channel 24-Bit digitizer, 3 orthogonal
OMNI geophones and a DEEPENDER hydrophone. The proprietary electronics and
sensors are packaged in a hermetically-sealed pressure housing. The sensor modules
are assembled at selected intervals forming continuous subsea sensor array receiver
cables. The module and cables feature bi-directional power and telemetry allowing
flexible in-water system configurability.

Built-in “Pitch and Roll” Inclinometer
The GeoRes SubSea 4C digitized sensor module has a built-in inclinometer that
measures the vertical orientation of the three (3)-axis orthogonal OMNI Geophones.
The subsea module measures the inclination (“pitch”) of the in-line OMNI geophone and
(“roll”) of the cross-line OMNI geophones thus eliminating the need for expensive gimbal
assemblies.

The subsea sensor array cable is designed specifically to maximize
the reliability of the in-water equipment. The subsea cables array
segments are manufactured in “customer-specified” lengths
depending on handling equipment and deck storage considerations.
4-component digitized sensors are assembled in pressure modules
containing power supplies, digitization and telemetry electronics then
packaged in a robust hermetically sealed pressure cylinder which is
over molded to the cable to form continuous “connector-less”
sensor/receiver seabed cables.

SETTING NEW STANDARDS FOR QUALITY DATA, HIGH PERFORMANCE ACQUISITION and UNMATCHED IN-WATER EQUIPMENT RELIABILITY
The OMNI Series geophone
provides a unique on axis
sensitivity regardless of tilt angle in
space. Each OMNI element have
the same specifications of
sensitivity, impedance, phase,
frequency response, and harmonic
distortion providing an ideal vector
fidelity response.
The mathematical precision of the
resulting measurements
significantly improves the
discrimination of plane wave
measurements at the detector.
DEEPENDER
HYDROPHONE
The DEEPENDER
hydrophone is a cylindrical
piezoelectric crystal uniquely
molded inside the housing of the
digitized sensor module.
The DEEPENDER
hydrophone operates to 3,500
meter water depths with less than
1.5 dB sensitivity change.
