Assignee:

Gushor Inc. - Calgary, Alberta

International Classification:

G01N 1/22

US Classification:

7386323

Abstract:

The invention relates to an apparatus and method to obtain a bitumen or heavy oil sample from an oil reservoir sample, such as a core sample, to enable measurement of physical properties such as viscosity, API gravity, or chemical properties such as sulphur content of the obtained bitumen or heavy oil sample. The analysis performed on the samples obtained in accordance with the invention are effective in assisting oil field operators in making timely drilling and production decisions at the oil reservoir or for routine laboratory extraction of oils and bitumens. The invention also permits the collection of samples from simulated thermal recovery operations and also allows the collection of bitumens and oils for online analysis of live oil physical properties.

Abstract:

A process is described for measuring a property of oil extracted from a sample, for example, the viscosity or density. The oil is extracted from the sample using a volatile polar first solvent. A portion of the extracted oil is used to determine a concentration factor. A dry weight of the oil in the sample is calculated using the concentration factor. A second solvent less volatile than the first solvent is added to the remaining extract. The first solvent is substantially removed from the remaining extract. Different amounts of the second solvent are removed from each of a series of sub-samples taken from the remaining extract. Solvent concentrations and viscosity values and/or density values of the solvent-oil mixtures are measured for each sub-sample. Based on the measured solvent concentrations and viscosity values and/or density values, the second-solvent free viscosity and/or density of the oil in the sample is estimated.
