<p>Apparatus to monitor the rheology of a drilling fluid or mud, that is used during the drilling for oil or gas, where monitoring is conducted in a continuous and in real time. Preferably the apparatus monitors common industry measures, such as the plastic viscosity and yield point of the drilling fluid and mud via two or more viscometers which monitors the changes in the rhelogical curve of a drilling mud, by monitoring the change in the low and/or medium and/or high shear rate portions of the rheological curve (fig E) created from the results of a rotational viscometer 1 on a computer or similar device 2. The computer 2 is linked to the viscometers D1, D2, D3, that monitor mud being pumped through separate sample chambers C1, C2, C3, thereby allowing the different shear rates to be monitored. The apparatus has at least one or more sample chambers of different sizes to generate different sheer rate on the common volumetric flow. Preferably the apparatus draws a continuous sample of the mud into the sample chambers C1, C2, C3 via at least one integral or external pump. The data from the apparatus may be sent electronically to other locations.</p> |
