Downhole Fluid Analysis Method And Apparatus For Determining Hydrogen Indexes

摘要

The present disclosure relates to determining hydrogen indexes of downhole fluids using fluid composition data. In certain embodiments, the type of the fluid, such as gas, water, or oil, may be determined downhole and used to select a method for determining the hydrogen index of the fluid. The selected method may then be employed while the tool is downhole to calculate the hydrogen index of the fluid.

主权项

1. A downhole fluid analysis method comprising:
analyzing formation fluid within a fluid analyzer of a downhole tool to determine properties of the formation fluid; determining a type of the formation fluid based on the determined properties of the formation fluid; selecting a method for calculating a hydrogen index of the formation fluid based on the determined type of the formation fluid; and calculating the hydrogen index of the formation fluid using the selected method while the downhole tool is disposed within a wellbore.
