Saldanadi Gas Field, Bangladesh

3. INTRODUCTION
Importance 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

4.  Modeling a reservoir with Petrel
 Interpretation of seismic data for pick horizons for
delineating seismic horizon
 Identifying faults in the area of study
 Delineating structure for the purpose of reservoir
modeling
 To correlate wire-line log and seismic data
 To create simulation of a reservoir model
 Simulation run with FrontSim
 History matching
OBJECTIVES OF STUDY

5. 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.

35. 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.
