BlueQube Acquisition

The key technology in BlueQube is Gravity Gradiometry Imaging (GGI) which measures the gradient of the earth's gravity field, effectively logging density variations in the underlying rocks. From this, a detailed structural geological picture can be determined, which can be used to help with lease decisions, overcoming seismic uncertainty, velocity modelling, prospect generation, prospect identification and drilling locations.

At the heart of BlueQube is a modified Lockheed Martin FTG (Full Tensor Gravity Gradiometer) which can be deployed on various survey platforms together with a range of other complimentary geophysical instruments as required.

Operational Modes

ARKeX use a number of different acquisition platforms to carry out BlueQube surveys. The type of platform deployed depends upon the geology and terrain of the target area. The ARKeX Operations Team works closely with you to determine the most appropriate platform to meet your objectives.

Cessna C208B Grand Caravan

Onshore - Airborne - Single engine plane

Aircraft: Cessna C208B Grand Caravan

Speed: 220km/hr (62m/sec)

Endurance: 4.5 hrs (with reserve)

Ideal for onshore work, the light nimble Cessna has proved itself to be the reliable workhorse of the survey industry. The plane carries the FTG (Full Tensor Gravity Gradiometer) along with magnetic field instrumentation, digital video recorder and LiDAR (Light Detection And Ranging). LiDAR is a digital mapping tool that provides a more accurate terrain correction in data processing.

De Havilland Canada DHC-6-200 Twin Otter

Transition Zones -Airborne - Twin engine plane

Aircraft: De Havilland Canada DHC-6-200 Twin Otter

Speed: 338 km/h (94m/sec)

Endurance: 4.5 hrs (with reserve)

Although also suitable for onshore work, the twin turbo-prop De Havilland makes a perfect platform for transition zone work. Onshore/offshore survey work demands a platform with increased range and stability that also meets the stringent QHSE requirements when flying over water.

Similar to the Cessna, the Twin Otter carries the FTG along with magnetic field instrumentation, digital video recorder and LiDAR.

BlueQube Marine ship

Offshore - BlueQube Marine

For marine work ARKeX use a vessel of opportunity. The equipment can be installed on your own vessel or one can be leased for the duration of the survey. In most cases the FTG is housed in a self-contained 20ft container fitted to the back deck. The vessel configuration includes:

  • FTG
  • Conventional Gravity
  • Magnetic Data (optional)
  • Multi or Single Beam Bathymetry

The instrument configuration can also be adapted to meet the needs and objectives of your survey.
