(BAPEX) Abstract In Bangladesh, most of the onshore part has been explored widely for natural gas, yet there is more possibility to explore the resource inland by remodeling and re-studying with modern techniques. Fenchuganj Gas Field is one of the producing gas fields located at northeastern part of Bangladesh. Five exploration wells (FNG-1, FNG-2, FNG-3, FNG-4 and FNG-5) have been drilled so far and two wells FNG-2 and FNG-3 are producing natural gas. Both the well FNG-1 and FNG-5 have been abandoned as dry wells. The well FNG-4 is still under evaluation. There are nine gas sands recognized are New Gas Sand IV (NGS IV), New Gas Sand III (NGS III), New Gas Sand V (NGS V), New Gas Sand II (NGS II), Upper Gas Sand (UGS), New Gas Sand I (NGS I), New Gas Sand VI (NGS VI), Middle Gas Sand (MGS) and Lower Gas Sand (LGS). Producing gas sands are UGS, MGS and LGS. Out of nine gas sands, seven have been modeled in this research work. The structure of Fenchuganj Gas field has re-studied with petrel simulation software by incorporating seismic and wirline log data. The gas sand horizons were picked and 3D time contour map and depth structure map of each horizon were made. Fault models have been made for fault interpretation. Two major reverse faults have been identified trending NNE-SSW in the study area. These faults divided the study area into three segments which can be named as western part, eastern part and faulted zone. Maps and models showed that the structure of the Fenchuganj Gas Field is almost NNE-SSW trending asymmetric anticlinal fold. The eastern flank is steeper than the western flank.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
