Q-Marine Technology Components

Calibrated sources

The signature of any air-gun source varies from shot-to-shot for a multitude of reasons, including gun dropouts and array movement; this variation reduces the accuracy and repeatability of seismic data. Q-Marine has an advanced digital source controller that provides a fully calibrated source signature derived for every shot utilizing the "notional source" method.

Calibrated positioning

Positioning knowledge is crucial for time-lapse and high-resolution reservoir seismic data.

Q-Marine has a positioning system for the in-sea seismic equipment that uses a fully braced acoustic positioning network from the front to the tail of the streamers, independent of streamer length, bringing seismic positioning accuracy to a new level.

Calibrated single sensors

Streamer sensitivity variations introduce perturbations into the seismic data. Q-Marine single sensors enable automatic calibration and "cleaning" of this footprint. Fully flexible spatial sampling will optimize specific survey objectives. Additionally, the single-sensor sampling enables powerful new filtering techniques to remove noise.

Steerable streamers

Q-Marine streamers contain the unique Q-Fin steering devices. These are remote controlled wings, integral to the streamer for reduced noise, which enable both precise depth control and horizontal steering. Horizontal streamer steering provides feather correction, safe streamer separation control, active steering for optimal coverage, and 4D repeatability.
