This document summarizes the process of reservoir modeling and simulation for the Saldanadi Gas Field in Bangladesh using Petrel 2009.1.1 and FrontSim software. The workflow includes collecting seismic, well, and production data; interpreting horizons and faults from seismic lines; developing structural and stratigraphic models; modeling properties; simulating initial conditions and production; and history matching simulation results to field data. The objectives are to better understand reservoir characteristics, locate new wells, and forecast production and investment needs to further develop the field.
Reservoir Modeling with Petrel
- 1. RESERVOIR MODELING WITH PETREL 2009.1.1 AND SIMULATION RUN WITH FRONTSIM Presented by Adeeba Rahman Setu 1007006 Supervised by Mr. Tareq-Uz-Zaman Assistant Professor Department of Petroleum & Mining Engineering
- 2. SELECTED FIELD 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

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.
