Investigation of the hydrocarbon potential of the Arsuz (Hatay) regional Kızıldere formasyon

The study area comprises Arsuz - HATAY region and the formation characteristics of the clay rocks of Kızıldere Formation (Middle - Upper Miocene) and sedimentation environment of formation were investigated. The petroleum-rich regions formed during the Miocene, these formations; Kalecik Formation (Middle Miocene) with conglomerates, Horu Formation (Middle Miocene) with reefal limestones and Kızıldere Formation. From these formations, Horu Formation with reservoir rock feature and Kızıldere Formation providing reservoir rock source rock and cap rock properties is important for petroleum potential. The Middle-Late Miocene aged Kızıldere Formation is typically observed in the Konacık (Arsuz) region. Sand and clay layers are common in the formation, bedding thickness of the gray-yellow colored sandstones are 10-50 cm (medium-thick), and gray claystones are 2-30 cm (thin-medium). Nodular and stratified gypsum layers are observed at the top of the succession of sandstone and claystone and gypsum layers thickness are 5-15 cm. Tectonic cracks in the formation are widely observed by virtue of tectonism that is effective after Middle Miocene in the region. Plant residues in marl that is layered with gypsum layers are macro-scale. The average total organic carbon (TOC) values in the claystones are 0.56 which indicates that there is a potential for oil production in claystones. The averages of the concentrations of trace elements are as follows: V-1180,65 ppm, Ni-219,83 ppm , Cr-149,26 ppm, Co-19,45 ppm, Cu-22,63 ppm, Rb-42,96 ppm, As-8,40 ppm, Zn-54,47 ppm, Sb-0,61 ppm, Mo-1,28 ppm, Cd - (- 0,71) ppm, Pb-5,68 ppm, U-1,35 ppm, Ba-171,15 ppm, Li-24,64 ppm, Cs-3,06 ppm is S-325.48 ppm. Increases in vanadium concentrations and V / Ni, Ni / Co, V (V + Ni), V / Cr ratios indicate that claystones are deposited in the marine and anoxic environment suitable for protection of organic matter. According to trace elements and TOC values, classification was made in cluster diagram and it was determined that the transition of environment conditions. The classification of trace elements and TOC values in the region and the environment transitions in which organic matter preservation increases were determined.
