Abstract
An apparatus to test a drilling fluid in a laboratory includes a test cell configured to test the fluid to determine a Sag Factor of the fluid. The test cell may be heated with a heating jacket to a predefined temperature. A plurality of densitometers are configured to continuously measure a density of the fluid circulating in the test cell. A computing device processes the density measurements to determine a Sag Factor of the drilling fluid.
Claims10
An apparatus to test a fluid in a laboratory, comprising:
- a test cell configured to test the fluid to determine a Sag Factor of the fluid;
- a heating jacket configured to receive the test cell and heat the test cell to a predefined temperature;
- a plurality of densitometers configured to continuously measure a density of the fluid disposed in the test cell;
- and
- at least one data line for transmitting the density measurements from the test cell to a computing device in the laboratory,
- wherein the computing device is configured to process the density measurements to determine the Sag Factor of the fluid, and
- wherein the heating jacket covers at least two faces of an exterior of the test cell.

A method for determining a Sag Factor of a fluid, comprising:
- obtaining a sample of the fluid to be analyzed;
- filling a laboratory test cell with the fluid to be analyzed;
- closing the laboratory test cell to seal the fluid inside and applying a selected pressure to the laboratory test cell;
- heating, via a heating jacket that covers at least two faces of an exterior of the laboratory test cell, the laboratory test cell to a selected temperature;
- measuring, via a plurality of densitometers, a density of the fluid inside the laboratory test cell under the selected pressure and temperature;
- transmitting the density measurement to a computing device for processing;
- and
- determining the Sag Factor of the fluid in the laboratory test cell.
