Coreflooding test results before the vibration effect can increase oil production by 51.96% and reduce the residual oil saturation by 59.03%. The surprising results when the vibration effect was applied to the coreflooding test method with P wave types continuously succeeded in increasing oil production by 60.54%, intermittent P waves by 63.53% and circular waves by 64.76%, while also reducing Sor by 48.49% in continuous P waves, intermittent P waves at 44.81% and C waves at 43.3%. The P wave type vibrational method has an increase in oil gain by 16%, intermittently by 22%, Sor reduction by 18% and 24%, in circular wave oil gain increases by 25%, and Sor decreases by 27% from before the vibration effect given. Besides vibration can change the physical properties of rocks, among others; permeability has increased by 7% using P waves continuously, intermittently by 31% and C waves by 4%; porosity of 5.88% with P waves continuously, intermittently of 6.46% and circular waves of 4.63%; grain size before vibration of 45.16 μm after vibration using continuous P waves of 42.01 μm, intermittently of 47.98 μm, and circular of 50.46 μm; changes in oil composition to contain more alkanes, and lack of aromatic compounds; oil viscosity increased by 3% with continuous P waves, intermittent of 5%, and circular 61%. The new point from this paper is analyzing the vibroseismic effect by using SEM images in terms of the watershed segmentation of the Rabbani algorithm compared to lab results, which have an error rate of under 2%, and a review of oil composition by the GC-MS method.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Chemical composition,Circular wave (C),Coreflooding,Enhanced oil recovery,Frequency,Longitudinal wave (P),Residual oil saturation (sor),Vibroseismic,Viscosity[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]We want to thank the researchers who provided input and direction related to the research and writing of this thesis; Barabanov as a Russian vibroseismic researcher, Arash Rabbani University of Manchester researcher, Huang Zeng BP Chemist, Diana Chirkova University of Manitoba researcher, Prof. Yana Maolana Syah, M.S.
