INTRODUCTIONImportance of Reservoir Modeling
o For new fields, 3D models may help development of the wells by identifying the number of wells required, the optimal completion of wells, the present and future needs for artificial lift and the expected production of oil, water and gas.
o For already developed fields to locate new well to increase oil and gas production

WHY SOFTWARE IS USED IN THE THESIS?
Analytical methods generally cannot capture all the details of the given reservoir or process.
In modern reservoir engineering, they are generally used as screening or preliminary evaluation.
Reservoir simulation models are used by oil and gas companies in the development of new fields.
Models are used in developed fields where production forecasts are needed to help make investment decisions.
Improvements in simulation software have lowered the time to develop a model.

CONCLUSION
In previous a static model was developed on this structure. A dynamic model along with simulation run has been developed in my thesis work.
Further to develop this reservoir: More attention should be given on new well
drilling study. It is recommended to carry out 3D seismic
survey before attempting any further drilling campaign over Saldanadi field.
