Using vessels of any type

It does not require a specially equipped node-handling vessel and can use any vessel of opportunity: instead of bulky node-on-a-rope deployment and retrieval equipment our technology applies built-in acoustic release system, which does not require special on-board handling mechanisms or special deployment sheaves or winches.

OBN self pop-up from the seabed

Water provides natural transportation environment for our buoyant node when it rises to the surface after by acoustic release disconnecting the OBN from the anchor weight that keeps it on the seafloor, which ensures better operational efficiency and speed.

Wireless downloading of data

After recovery the recorded data are downloaded from the nodes via high speed wireless link without opening of the housing, which speeds up the shipboard operations and ensures data QC every node redeployment.

90 days of autonomous operations

The nodes have been optimized for low power consumption, which increases their autonomy time and ensures reliable long-term operations without recharging/change of the OBN battery during the survey time.

Night operations

The nodes are equipped with LED lamp, which ensures their fast location on the sea surface during the night hours.

Built-in GPS module

Built-in GPS module ensures accurate location of the OBN unit after surfacing.

High data quality

Seafloor positioning

Exact seafloor positions of the nodes are provided by the acoustic transponders mounted on the OBS units.

Significant improvement of signal-to-noise ratio

Rope-free operations provide good separation of stationary sensors from the sea surface, hence improved signal-to-noise ratio in a quieter seafloor environment (especially in shallow sea).

Four-component full azimuth survey

Allows to capture not only compressional waves, but also shear waves, as well as converted waves, which provides higher quality imaging results.

Additional direct hydrocarbon and lithology indicators

Apart from conventional seismic tools low-frequency component of seismic data can provide valuable information for use of direct hydrocarbon indicators, without additional cost to the client.

Operations in most challenging environments

Deep see, with depths from 0 to 7000 meters

Various bottom topography

Oil platforms and heavy marine traffic

Sea bottom obstacles, such as rocks, pipelines, shipwreck, etc.

Tidal area, rough sea conditions

In Arctic areas, ice sea conditions

How It Works

1 Этап

Problems Addressed

Sea bottom multicomponent full azimuth 3D seismic survey with unlimited acquisition aperture overcomes “blind spots” of conventional offshore acquisition technology. It can provide reliable delineation of fractured reservoirs and obtain seismic image of a target under a seismic obscured zones such as gas cups, basalt or salt structures.

  • Identification and imaging of dry or fluid-saturated fractured reservoirs
  • Imaging of structures under complex overburdens
  • Such as sub-basalt and sub-salt structures
  • Gas chimneys and sea-floor seeps
