In this research, a simple experimental setup for fluid contact angle measurement is constructed using an optical microscope and video camera with 29 frames per second. Measurement of contact angle of fluid with variation of salinity, i.e.: 1M, 2M, 3M, 4M, and 5M is carried out by recording a single droplet placed on a rock surface. Each frame of the recorded video are then analysed using image processing technique to detect the edge and calculate the contact angle. A single 8th order polynomial was applied to the edge of the wetting type droplet, but two types of polynomial fitting curves are applied for edge of non-wetting type droplet. It is obtained that on preparatory glass, the higher the molarity, the longer the droplet will evaporated. On the sandstone surface, fluid contact angle on sandstone surface is about 80° and decreases with time with different trend of decrement. This may be due to complex interaction between fluid and pores at sandstone surface spot.[/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]Contact angle of fluids,Enhanced oil recovery,Frames per seconds,Image processing technique,Order polynomials,Polynomial fittings,Salinity variations,Single droplet[/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][/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]This research was funded by the research program from Ministry of Research, Technology, and Higher Education of The Republic of Indonesia (Kementrian Riset Teknologi dan Pendidikan Tinggi Republik Indonesia).[/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=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1755-1315/311/1/012035[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
