Abstract

Methods for determining fluid rheology, the methods including determining a first discharged volume or weight of a fluid at a first time, determining at least a second discharged volume or weight of the fluid at a second time, and calculating fluid rheology based on the determined first and at least second discharged fluid volumes or weights at the first and second times.

First claim

What is claimed:

1. A method for determining fluid rheology, the method comprising:
determining a first discharged volume or weight of a fluid passed through a Marsh funnel into a measuring cup at a first time;
determining at least a second discharged volume or weight of the fluid passed through the Marsh funnel into the measure cup at a second time; and
calculating, by a logic controller in operative communication with the Marsh funnel and the measuring cup, fluid rheology based on the determined first and at least second discharged fluid volumes or weights at the first and second times.

2. The method of claim 1 , wherein the method comprises at least one of a: Newtonian model, Power-Law model, Bingham plastic model and Herschel-Bulkley model.

3. The method of claim 1 , wherein the determining further comprises:
converting the determined first discharged volume or weight at the first time to a first height at the first time; and
converting the determined at least second discharged volume or weight at the second time to a second height at the second time.

4. The method of claim 1 , wherein the calculating further comprises: characterizing the fluid rheology from the determined funnel data through an optimization algorithm.

5. The method of claim 4 , wherein the optimization algorithm comprises the average deviation function:

6. The method of claim 1 , further comprising:
determining density of the fluid.

7. A system for determining fluid rheology comprising:
a Marsh funnel having a fluid inlet and a fluid outlet disposed in a housing;
a measuring cup disposed in fluid communication with the fluid outlet of the Marsh funnel;
a weight measurement device disposed proximate the measuring cup and configured to determine a weight of the measuring cup;
a logic controller in operative communication with the Marsh funnel, the measuring cup, and the weight measurement device, wherein the logic controller is configured to determine the fluid rheology based on the weight of the fluid in the measuring cup at a time interval.

8. The system of claim 7 , further comprising:
a density measurement device disposed proximate at least one of the Marsh funnel and the measuring cup, wherein the density measurement device is configured to determine a density of the fluid.

9. The system of claim 7 , wherein the logic controller further comprises program code to calculate fluid rheology of the fluid based on determined volumes or weights of the fluid at a particular time interval.

10. The system of claim 7 , wherein the program code calculates the fluid rheology based on at least two determined fluid volumes or weights determined at two separate time intervals.

11. The system of claim 7 , wherein the logic controller is operatively connected to a remote communication network.

12. The system of claim 11 , wherein the system is controlled remotely over the remote communication network.

13. The system of claim 7 , wherein a temperature of the fluid and a pressure in the housing is monitored over the remote communication network.

14. The system of claim 7 , wherein fluid rheology is automatically calculated by the logic controller.

15. The system of claim 7 , further comprising a fluid injection line in fluid communication with the Marsh funnel and the measuring cup.

16. The system of claim 7 , further comprising:
a temperature measurement device to determine temperature of the tested fluid;
a pressure measurement device to determine pressure in the housing.

17. A method for automated fluid rheology calculation at
