Reservoir Challenges VS Solutions

 

Challenges	Solutions
ü Reservoir Heterogeneity :           -   Lateral and vertical facies changes     -    Depositionnel environnements modelling.	Reservoirs Characterization using integrated seismic interpretation, inversion, geologic modelling with sedimentological studies.
ü  Structure Complexity -    Structural pattern is very complex, especially in the deeper Paleozoic section. -          Multi tectonic phases. -          Seismic data mask by multiples.	Ø  Overcome by sophisticated structural seismic attributes (faults likelihood as example) to detect most of faults trends. Ø  Understanding the geologic and structure setting. Ø  Structure restoration.
ü  Defining potential blocks. ü  Defining the reservoir quality.	Ø  Integrating structural interpretation with seismic attributes, available petrophysical and Engineering data.
ü  Compartimentalization	Ø  Optimized structural configuration. Ø  PVT @Pressure Analysis. Ø  Fault seal Analysis.
ü  Low resistivity pays	Ø  Conductivity of clay and minerals. Ø  Micro porosity and high irreducible water saturation. Ø  Deep invasion of high salinity filtrate.
