Asphaltene Gradient Modeling Methods |
| 摘要 |
The present disclosure relates to methods and systems for developing an equation of state model for petroleum fluids. In one embodiment, formation fluid from a plurality of depths within a wellbore may be analyzed to determine a change in a gas oil ratio with respect to depth. The change in the gas oil ratio may be employed to determine a ratio of solubility and entropy terms to a gravity term. The resulting ratio can be used to develop the equation of state model. |

1. A modeling method comprising:
analyzing formation fluid within a fluid analyzer of a downhole tool at a plurality of stations to determine a change in a gas oil ratio with respect to depth; employing the change in the gas oil ratio with respect to depth to determine a ratio of a solubility term and an entropy term to a gravity term; and developing an equation of state model based on the ratio. |
