4D seismic processing pilot monitors reservoir offshore Qatar ///

In 4D seismic, the four dimensions are X, Y, Z and Time. To monitor a field and its production, 4D seismic technology uses two 3D seismic cubes, spaced by months or years. At the end of the 4D processing, two seismic cubes named Base and Monitor are obtained, each one representing a slightly different observation of the same geology. It will bring unbiased information, as it is an observation without any a prior data. It allows maximizing oil recovery, optimizing infill-well positioning, managing injection and offtake, and monitoring geomechanical effects.
