Abstract
Methods and apparatus for determining a viscosity of oil in a mixture are disclosed herein. An example method includes determining water fractions of a mixture flowing into a downhole tool and determining viscosities of the mixture. The mixture includes water and oil. The example method also includes determining a viscosity of the oil based on the water fractions and the viscosities.
Claims20
A method, comprising:
- determining water fractions of a mixture flowing into a downhole tool, wherein the mixture includes water and oil;
- determining viscosities of the mixture;
- and
- determining a viscosity of the oil based on the water fractions and the viscosities.
A method, comprising:
- determining a viscosity of a flowing mixture as a function of a fraction of a dispersed phase of the mixture;
- and
- extrapolating the fraction of the dispersed phase to zero.
A tangible article of manufacture storing machine readable instructions which, when executed, cause a machine to:
- determine water fractions of a mixture flowing into a downhole tool, wherein the mixture includes water and oil;
- determine viscosities of the mixture;
- and
- determine a viscosity of the oil based on the water fractions and the viscosities.
The tangible article of manufacture of 16 wherein the machine readable instructions, when executed, cause the machine to determine the water fractions of the mixture by determining optical densities of the mixture.
