Recording Equipment

Universality:
profitability in the seismic environment

Developing the best seismic equipment in the world is one thing, getting it to work in a variety of environments is a different challenge. Our dedicated Geo-X professionals, working with our clients, enabled us to develop the Uni-RAM and the Uni-TAP. These units allow you the freedom, flexibility and peace of mind to know the recording system will work, wherever you’re working. Uni-RAM is a universal solution from mountain top to shallow ocean bottom.

Combined with other ARAM-ARIES features Uni-RAM provides continuous coverage through the use of:

  • Connector technology
  • Superior water protection
  • Auto-routing Fire by Wire
  • "Wireless" repeater technology
 

...whatever conditions dictate.

Reliability and productivity of the ARAM.ARIES system is enhanced by multiple baseline and redundant cable connection technology. This allows the data-collection process to continue, uninterrupted, even in the event of a broken or cut cable. The most complex "Layouts" become an easy to use reality with the touch of a mouse.
This attention to both sturdiness and
reliability make ARAM.ARIES and
Uni-RAM the universal solution
for today’s seismic
environment.

 

Adaptability
and redundancy mean gains in productivity

ARAM.ARIES is unparalleled in its adaptability to various seismic environments. This is aided by built in System Wide Redundancy (SWR). SWR provides you with the ability to keep shooting with no interruptions and also protects your seismic data from the channel to the tape:

  • Shot memory
  • Error- free Data Recovery
  • Redundant Telemetry Acquisition
  • Dual transmission in RAMs and cable
  • Multiple transmission in TAPs and Baseline
  • Redundant cable connection technology
  • Redundant Line Card connections
  • Mirrored hard drives

SRW is a pre-requisite for the growing demand for Mega-channel recording

Portability is logistics

Size and weight has an impact on all aspects of collecting seismic information. Those most effected by the weight of seismic equipment may appear to be the crew responsible for setting it up and taking it down. But size and weight also have impact on:

  • Environmental footprint
  • Crew size
  • Health and Safety
  • Mobilization costs
  • Equipment movement in the field
  • Overall productivity

That's why ARAM.ARIES is designed to be the smallest, lightest system in field today

 

Emerging trends
require Mega-channels.

Advances in High Definition 3D, Single Point Recording, Multi-Component Recording, and an increased need for gains in productivity and data quality for traditional 3D acquisition-are all reasons for the industry's call for increased channel availability-Mega-channel Recording. To answer this demand Geo-X has developed:

  • Variable Transmission Rates which optimizes system performance at all takeout intervals.
  • Independent transmission rates in the new ARIES Line Tap Unit which optimize channel capacity throughout the entire network.

Mega-channel operations are also a reality today because the ARAM.ARIES system can handle in excess of 39,000 channels in real time and virtually an unlimited number of channels in near-real time.

These unique features of our system in conjunction with system wide Redundancy makes Mega-channel acquisition possible.
