Abstract
A rheology device comprises an elongated body having a flow path defined therein, first and second pressure lines in communication with the first and second ends of the flow path, respectively, and a differential pressure sensor for measuring a difference in pressure between the first and second pressure lines. In embodiments, the pressure lines are filled with a spacer fluid different from the fluid in the flow path. Based on at least three measurements of difference in pressure and corresponding flow rates, a yield point, a consistency factor, and a power factor can be calculated, and a rheology model of the fluid can be generated. Related methods are described which allow fluid rheology models to be determined and updated frequently. The device and methods herein may be useful in oil and gas operations, for example for rheology and hydraulic modeling in drilling operations.
