An Experimental Study of the Oil Production from Domanik Formation Rocks Under Hydrothermal Conditions

Abstract

The experimental results on synthetic oil production from rocks of the Domanik Formation under hydrothermal conditions are reported. The potential for oil-product extraction from the oil fractions of the rocks under a hydrothermal impact was up to 60 mg/g or 6.0 wt %. The injection of inorganic additives (sodium carbonate or silica gel) did not increase the oil-recovery factor. As well, the amount of the recoverable oil products directly depended on the mineral composition of the rocks. The relationship between the percentage of hydrocarbon yield and the mineral composition of the rocks was determined. Clay minerals and silica increased the yield of synthetic oil; carbonates, conversely, inhibit the process.
