Lithofacies variation of Lower Cretaceous sedimentary succession: An interaction of paleo-high and mixed carbonate- clastic system and its consequence on the distribution of reservoir units in Abadan plain, SW-Iran
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2017, Vol 10, Issue 4
Abstract
The Neocomian Fahliyan Formation as a prolific hydrocarbon reservoir in the Abadan Plain, show remarkable lithofacies variation. In the current work, integrating geological, geophysical and petrophysical log data from more than 10 wells belong to six oil fields, the lithofacies variation as a prominent factor affecting the reservoir quality was studied. Also, paleontological investigation were carried out on a number of 253 microscopic thin sections from well A-1,to differentiate the Upper Fahliyan marginal marine fine-grained classic from basinal argillaceous facies of Garau Formation. Moreover, for clay mineral identification as a possible indicator of sedimentary facies, six XRD analysis was conducted. Detailed well log correlation complemented by seismic sections in a regional scale, help us better understand the sedimentary model of the Lower Cretaceous sedimentary succession. Sequence-wised stratigraphic correlation revealed that the facies variation of Lower Cretaceous sedimentary succession influenced from both regional and local parameters. As a conclusion, the lithofacies of the Lower Cretaceous sedimentary succession is the record of the interplay of regional dip of the platform, paleo-high geometry, clastic intrusion from South-West, channeling system pattern and structural lineaments, all affecting the reservoir thickness and quality of the Lower Fahliyan.
