摘要 |
A system and method for determining the asphaltene content of a downhole oil sample are provided. In one example, the method includes obtaining a hydrocarbon sample from a hydrocarbon formation of a reservoir at a given depth using a downhole tool. A liquid phase of the hydrocarbon sample is isolated within the downhole tool and the liquid phase is subjected to downhole analysis within the downhole tool to create a chromatography sample. The downhole analysis is based at least partially on size exclusion chromatography. A first property of the chromatography sample is measured to obtain a measured value, and a second property of the chromatography sample is estimated based on the measured value and known calibration curves. |
