3D modeling of biogenic gas-bearing Neogene deposits at Arkalochori region, Messara, Crete, Greece3D modeling of biogenic gas-bearing Neogene deposits at Arkalochori region, Messara, Crete, Greece Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2015-10-302011enNumerous biogenic methane gas seepages in Arkalochori region of Central Crete were the motivation to explore the gas potential of the area. According to recent studies, the gases seem to be of biogenic rather than thermogenic origin. To quantify the size of the potential reservoir, the construction of a 3D model concerning the shallow Neogene sediments of the area became essential. The available data needed for the construction was scarce, so in order to enrich our data pseudo-boreholes were introduced. The resulting lithostratigraphic model honors the main structural characteristics and the spatial distribution of Neogene deposits, specifically those that belong to Tefelion Group. A 3D lithostratigraphic model in combination with sedimentological observations could assist in delineating possible locations of gas accumulation so that they could be examined thoroughly in the futurehttp://creativecommons.org/licenses/by/4.0/International Association for Mathematical Geosciences Manoutsoglou Emmanouil Μανουτσογλου Εμμανουηλ Pyliotis Ioannis Πυλιωτης Ιωαννης Panagopoulos Georgios Παναγοπουλος Γεωργιος Avraam Zelilidis Evangelos Spyridonos Vafidis, Antonios, 1958- Geology--Surveys geological surveys geology surveys
