Repeatability for Time-Lapse Surveys

The only truly 4D Ready system

The first Q-on-Q time-lapse monitoring survey was completed in the summer of 2003. Over 90% of the survey was shot with a feather match within one degree of the 2001 survey.

Q-Marine repeatability and rapid Q processing led to interpreted time-lapse effects that prompted a revision of the field drilling program within a month of acquisition.

System calibration - streamer steering - positioning accuracy

Fully calibrated sources, receivers, and positioning, in combination with streamer steering, allow Q-Marine surveys to be significantly more repeatable than conventional acquisition. Navigation data from Q surveys can be programmed to dictate shot and streamer positioning on subsequent Q surveys.

Compared to 4D surveys acquired with conventional technology, Q-Marine 4D surveys have typically shown a three-fold improvement in repeatability.
