f Integrated study of an unconsolidated reservoir

The following two objectives were sought in order to improve volumetric analyses and to enhance the production of a field from the North Sea: map the gas/oil contact, and its evolution through time as the field is produced, and identify areas of high permeability. By integrating petrophysical data such as empirically derived porosity-permeability relationships for each facies, an attempt is made at characterizing the seismic response of high permeability sands and to identify them seismically.
