Q-Marine Point-Receiver Marine Seismic System

Overview Library

High-fidelity seismic images for reliable mapping of complex reservoir features

The Q-Marine point-receiver marine seismic system was launched in 2000 and introduced multiple new concepts to the towed-streamer market. The Q-Marine system set the benchmark for other acquisition technologies and continues to perform at the highest levels today. Since its introduction, the system has successfully delivered across the full spectrum of basins and environments around the world. At all stages across the E&P cycle, the Q-Marine system delivers essential value through high resolution and repeatability within required reservoir time frames.

Point-receiver measurements

A major source of the noise that seriously affects marine seismic data quality and repeatability is related to weather and sea conditions. The Q-Marine system uses single-sensor recording to characterize noise with sufficient spatial fidelity, eliminating it using targeted digital filtering techniques. Unlike conventional noise suppression, this does not affect the signal bandwidth or fidelity.

Steerable streamers

The Q-Marine system pioneered steerable streamers by introducing the Q-Fin marine seismic streamer steering system. The Q-Fin system's remote-controlled wings reduce noise and 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.

Calibrated sources and positioning

The signature of any seismic source varies from shot to shot for a multitude of reasons, including source dropouts and array movement. This variation reduces the accuracy and repeatability of seismic data. The Q-Marine system has an advanced digital source controller that enables calibrated marine source—a fully calibrated source signature derived for every shot utilizing the notional source method.

Positioning knowledge is crucial for time-lapse and high-resolution reservoir seismic data. The Q-Marine system 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.
