    Abstract: The present disclosure relates to methods of controlling a microbial level in an aqueous fluid or a solid component used in an oilfield operation or a pre- or post-production process associated with wellbore production, the method comprising: measuring a microbial parameter of the aqueous fluid; and subsequently using the measured microbial parameter to decide on an appropriate antimicrobial treatment. These proposals also relate to methods further including monitoring of a microbial parameter in such a fluid or on such a solid component over a period of time. The methods and aspects of the present disclosure may be applied in any oilfield operation or a pre- or post-production process associated with wellbore production.

    CPC classification number: G01N11/14

    Abstract: A method includes disposing an open end of a housing in a wellbore fluid, flowing the wellbore fluid into the housing though the open end, rotating an impeller disposed within the housing at a first rotational speed with a motor coupled to the impeller, and determining at least one of viscosity and rheology of the wellbore fluid based on the rotating an impeller. An apparatus includes a housing, a mechanical agitator disposed in the housing, a motor operatively coupled to the mechanical agitator, a first sensor coupled to at least one of the mechanical agitator and the motor, and a second sensor disposed in the housing and configured to measure a fluid property or characteristic.
