Reliability

Q-Marine technology enables the identification of the key sources of noise and error that impact reliable seismic data quality and repeatability. Its main components include:

	Calibrated sources The signature of any airgun 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 has 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 optimizes specific survey objectives. Additionally, the single-sensor sampling enables powerful new filtering techniques to remove noise.
