Innovative integrated reservoir modeling technology based on latest achievements in seismic processing, rock physics, integrated reservoir/facility modeling, and production optimization is presented. The developed methodology differs from existing approaches in four distinct ways:
1. It provides a step-by-step procedure for building reservoir models based on all available seismic, well log/core, and production data. Latest achievements in geophysics are applied for the construction of sand/shale 3-D volumes based on seismic spectral decomposition. Object based geostatistical modeling is used for the construction of the 3-D facies models constrained by well data and seismically derived sand/shale 3-D volume. Correlations from rock physics are utilized to directly derive rock properties from seismic attributes.
2. It integrates models of multiphase fluid flow in reservoir, well tubing strings, pipeline system, and separation facilities into one system. It allows answering on the crucial question: What happens to the production profile if you modify facilities?
3. It utilizes 4D seismic technology for reservoir model validation and for making business decisions. Flow barriers and fluid movements derived from 4-D seismic are applied.
4. It incorporates field production optimization technology for optimizing well production rates and surface pipeline network structure in giant oil fields.
Significant business value has been added with the new technology applications for the optimization of infill drilling, waterflood, and facility modification programs which are supported by reservoir studies in GOM,
