  • What is 4D seismic method?

    By recording 3-D seismic data over the field at various time intervals, which may be from months to years, we introduce the fourth dimension to the the analysis of the data — calendar time, thus the term 4-D seismic method to describe the time-lapse 3-D seismic exploration.

  • What is 4D seismic monitoring of CO2 sequestration?

    4D seismic involves repeating 3D seismic surveys in time-lapse mode to image changes in the subsurface over time, whether due to injection or depletion in a hydrocarbon reservoir, injection and storage of CO2 for sequestration projects, or other subsurface processes such as groundwater flow or environmental contaminant

  • What is the difference between 3D seismic and 4D seismic?

    These are known as 4D surveys or time-lapse surveys, and hence the data density is higher over the same area, over a period of time because there are multiple data points over the same location. In general, 4D data density per unit area is higher than 3D, which in turn is higher than 2D.
  • 4D, or time-lapse, seismic is the process of using 3D seismic data acquired at different times, over the same area. It is used to assess changes in a producing hydrocarbon reservoir over time (the fourth dimension). Changes may be observed in fluid location and saturation, pressure and temperature.
