Measuring Properties and Amount of Producible Oil in Shale-Oil Reservoir Samples

摘要

The subject matter of the present disclosure is directed to developing a method of measuring the amount of producible oil and the producible oil saturation in shale-oil reservoirs using sample source rock. Further, the physical and chemical properties and amounts of producible oil in shale-oil reservoir samples may be determined. First and second solvents are applied to a sample source rock to extract petroleum from the sample source rock. The extracted source rock, the twice-extracted source rock, and the first and second extracted petroleum may be analyzed to determine the characteristics and properties of the reservoir rock.

1. A method for analyzing the chemical properties of a shale-oil reservoir rock, comprising:
extracting a core sample of a shale-oil reservoir rock using a weak solvent to form an extracted core sample and an extracted petroleum; drying the extracted core sample to evaporate the weak solvent; obtaining first data on the extracted core sample; extracting the extracted core sample using a strong solvent to form a twice-extracted core sample and a second solvent-extracted petroleum; drying the twice-extracted core sample to evaporate the strong solvent; obtaining second data on the twice-extracted core sample; and correlating the first and second data to determine producible oil quantities for the shale-oil reservoir rock.
