Abstract
Seismic systems and methods are provided to synchronize both source and receiver data using inexpensive timers and/or low energy timers to obtain high resolution seismic data.
Claims5
A seismic recording system comprising:
- a) a seismic energy source,
- b) an autonomous data recorder with a field timer that records field time,
- c) a standard timer that records standard time,
- c1) a control timer that records control time,
- d) a processor that corrects the field time from the field timer (b) by using a regional drift, wherein the regional drift is a correction factor calculated using recorded control time and standard time,
- e) calculating a regression-based model of the regional drift;
- and
- f) modifying the field time using the calculated regional drift.
