Abstract
A fluid sensor (and method) for determining at least one parameter of a fluid of a wellbore is provided. The fluid sensor has a base positionable in the wellbore, a base electrode operatively positionable in the insulation, and a raised electrode having at least one base portion and at least one raised portion. The base comprises insulation. The base portion is operatively positionable in the insulation. The at least one raised portion is positionable a distance above the base electrode such that a space is defined therebetween for the passage of the wellbore fluid therethrough. A voltage is applied across the base electrode and the raised electrode to generate a current therebetween whereby at least one parameter of the wellbore fluid may be determined. The fluid sensor is deployable into the wellbore via the downhole tool.
