Comparison of the Outcrop with Subsurface Geology and Hydrocarbon Prospect of Jaintiapur and Adjacent Areas in Northeastern Bangladesh | Chapter 3 | Emerging Issues in Environment, Geography and Earth Science Vol. 3

 The appearance of hydrocarbons in Bangladesh's eastern domain suggests that the Bengal basin has alive petroleum methods. The relationship betwixt structural configuration, tectonostratigraphic foundation, and hydrocarbon potentiality in the Surma tub, including the Jaintiapur region, has not yet been settled despite exhaustive research in the region. This work linked outcrop geology and subsurface tectonic data understanding along the L13-01, PK-SY-5, and L13-03 lines to judge the hydrocarbon prospectivity of Jaintiapur and the surrounding Dupigaon area. Based on order stratigraphy in the Sylhet region from projection, seismic, and well-log dossier, the primary three megasequences have existed identified. Surma pot covers the northeastern part of the Bengal basin, exhibiting a promising oil-bearing pan in southeast Asia. Eleven litho-stratigraphic units can be used to classification the exposed Tertiary and Quaternary rocks of Jaintiapur and the environment. These rock units were located in fluvial, deltaic, and shallow marine backgrounds, according to particularized facies investigations. Data from the Sylhet-7, Kailashtila-4, and Jalalabad-1 wells have existed used to determine the underlying lithology of the research domain. The Dauki Fault System dominates the tectonically complicated responsibility where the Jaintiapur domain is located. Intense rock deformation maybe seen in the extent through folding and forsake. Geological studies of the surface and subsurface reveal that faults run near side of rivers while transverse mistakes divide reservoirs. The Petrel program has been used to interpret a total of seven skylines. Based on transverse faults and size anomalies at the PK-SY-5 line that have unconnected bright spots, the seismic attribute study identifies leads and prospects. It appears that the unchanging gas-significance sand is present in the Sylhet-7 well and the surrounding district in the Dupigaon based on basaltic interpretation, attribute analysis, and lithofacies dispersion. The gas sands of the Sylhet-7 well signify the possibility of vapor/oil in the equivalent sedimentary order in the Dupigaon structure as this field is located nearly and more down-dip towards the kitchen extent.
