Seismic Logging Systems,
Data Acquisition, Quality Control, Processing and
Communications
Baker Atlas Downhole Seismic Services (DSS) offers a
complete range of purpose-built dedicated seismic logging
systems. From a fully integrated system with borehole
seismic capabilities, within the openhole ECLIPS™ logging
unit – to a stand-alone borehole seismic data acquisition
system, to portable PC-based system – the DSS systems
allow for quick deployment and remote operations.All
DSS seismic logging systems are efficient and reliable
data acquisition systems for all borehole seismic
applications. These systems allow for detailed quality
control of all aspects of the service, including downhole
data integrity, surface and downhole instrumentation
tests, source monitoring and navigation information to
ensure data quality.
The seismic logging systems have the flexibility to record
digital and analog downhole receivers and surface
channels. And also an interface with 3D surface seismic
systems allowing for simultaneous surface and downhole
data acquisition.
Real-time QC displays permit the field engineer to monitor
energy source firing, raw data recording, tool depth and
cable tension. Borehole seismic data field processing is
performed using a wide range of processing capabilities at
the well site. Data transmission from location to office
or to our processing and interpretation centers is also
possible by traditional dial-up, wireless and satellite
communication methods. |

Integrated Tasman
Navigation SystemThe Downhole Seismic Services (DSS)
Tasman navigation system meets or exceed all
specifications for land and marine VSP positioning
accuracy, QC and reporting. Using multiple Differential
Global Positioning Systems (DGPS), from local reference
stations to satellite-conveyed corrections, accurate
navigation positioning can be performed anywhere in the
world. Custom software packages, running on a PC
platform, control and log all position data, provide
real-time QC displays and manage telemetry between the
source and the recording unit from the simplest surveys
to the most complex 3D.
The DSS purpose-built Tasman navigation system provides
highly accurate, repeatable, shotpoint positioning in
any pattern. An extended interface protocol between DSS
Tasman navigation and the seismic acquisition system
ensures accurate and comprehensive recording of all
survey parameters and positioning data.
Energy Source Controllers
Baker Atlas DSS seismic
logging systems interface with all vibrator electronics,
airgun and explosives controllers. Our proprietary
airgun controller provides a major advance in VSP airgun
synchronization. It is capable of controlling up to 16
airguns at each eight-source location, using
micro-embedded PC controls to automatically tune large
airgun arrays and record individual gun-timing, sensor
signals, near- and far-field hydrophones, gun pressure
and depth information. |
