The high significance lies in the immobile portion of the oil, that is usually left behind, occurring as impregnations with a tendency to adsorb on the mineral surfaces of the pores (Leythaeuser et al., 2007). In terms of hydrocarbon recovery, numerous studies have addressed wettability as a key factor controlling fluid distribution in carbonate reservoir pores. In this study, we propose an integrated geochemical and petrophysical approach to (1) investigate the petrophysical control on the distribution of hydrocarbon fluids of varying compositions in carbonate core samples of varying modality, (2) analyze the molecular composition of the adsorbed oil, and (3) experimentally quantify the impact of hydrocarbon composition on reservoir wettability changes.Keywords: pore-scale fluid distribution, oil composition, carbonate pore network, wettability properties, biomarkers fingerprintingPermalink: https://doi.org/10.1190/image2022-3745518.1FiguresReferencesRelatedDetails Second International Meeting for Applied Geoscience & EnergyISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2022 Pages: 3694 publication data© 2022 Published in electronic format with permission by the Society of Exploration Geophysicists and the American Association of Petroleum GeologistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 15 Aug 2022 CITATION INFORMATION Maram AlSaif, Mustafa Hakimuddin, Khaled Arouri, and Ibrahim Atwah, (2022), "The impact of oil composition on fluid distribution in a reservoir pore network," SEG Technical Program Expanded Abstracts : 1071-1073. https://doi.org/10.1190/image2022-3745518.1 Plain-Language Summary Keywordspore-scale fluid distributionoil compositioncarbonate pore networkwettability propertiesbiomarkers fingerprintingPDF DownloadLoading ...
