Abstract

A drilling fluid conditioning system can include a centrifuge, and at least one heat transfer property sensor that outputs real time measurements of a heat transfer property of a drilling fluid that flows through the centrifuge. A method can include measuring a heat transfer property of a drilling fluid, and determining, based on the measured heat transfer property, an operational parameter of a centrifuge through which the drilling fluid flows. A well system can include a drilling fluid that circulates through a wellbore, and a drilling fluid conditioning system including a centrifuge and at least one heat transfer property sensor that measures a heat transfer property of the drilling fluid.

First claim

What is claimed is:

1. A drilling fluid conditioning system for conditioning a drilling fluid, comprising:
a centrifuge;
a first heat transfer property sensor that outputs real time measurements of a heat transfer property of the drilling fluid that flows through a first output of the centrifuge; and
a controller that adjusts operation of the centrifuge in response to the measurements of the heat transfer property of the drilling fluid.

2. The drilling fluid conditioning system of claim 1 , further comprising a second heat transfer property sensor configured to measure the heat transfer property of the drilling fluid that flows through an input to the centrifuge.

3. The drilling fluid conditioning system of claim 1 , further comprising a second heat transfer property sensor configured to measure the heat transfer property of the drilling fluid that flows through a second output of the centrifuge.

4. The drilling fluid conditioning system of claim 3 , further comprising a third heat transfer property sensor configured to measure the heat transfer property of the drilling fluid that flows through an input to the centrifuge.

5. A method, comprising:
measuring a heat transfer property of a drilling fluid flowing through a first output of a centrifuge with a first heat transfer property sensor; and
determining, based on the measured heat transfer property, an operational parameter of flail the centrifuge through which the drilling fluid flows with a controller.

6. The method of claim 5 , wherein measuring the heat transfer property of the drilling fluid further comprises measuring the heat transfer property of the drilling fluid flowing through an input of the centrifuge with a second heat transfer property sensor.

7. The method of claim 5 , wherein measuring the heat transfer property of the drilling fluid further comprises measuring the heat transfer property of the drilling fluid flowing through a second output of the centrifuge with a second heat transfer property sensor.

8. The method of claim 6 , wherein the determining further comprises comparing heat transfer property measurements of the drilling fluid flowing through the input and the first output of the centrifuge.

9. The method of claim 8 , further comprising adjusting operation of the centrifuge in response to the comparing.

10. The method of claim 5 , further comprising controlling operation of the centrifuge in real time in response to the determining.

11. The method of claim 5 , wherein the measuring further comprises outputting the heat transfer property in real time.

12. A well system, comprising:
a drilling fluid that circulates through a wellbore and a drilling fluid conditioning system, wherein the drilling fluid conditioning system comprises a centrifuge, and a first heat transfer property sensor that measures a heat transfer property of the drilling fluid flowing through a first output of the centrifuge; and
a controller that adjusts operation of the centrifuge in response to the measurements of the heat transfer property of the drilling fluid.

13. The well system of claim 12 , further comprising a second heat transfer property sensor configured to measure the heat transfer property of the drilling fluid flowing through an input to the centrifuge.

14. The well system of claim 12 , further comprising a second heat transfer property sensor configured to measure the heat transfer property of the drilling fluid flowing through a second output of the centrifuge.

15. The well system of claim 14 , further comprising a third heat transfer property sensor configured to measure the heat transfer property of the drilling fluid flowing through an input to the centrifuge.
