Abstract
Abstract: A method and device for separating particles from injection water, the injection water being used for the stimulation of a petroleum reservoir. The water is drawn from a water reservoir, cleaned and typically treated by means of additives before being led into the petroleum reservoir. The injection water is first led into a closed space (14), in which the flow rate is sufficiently low for undesired particles to precipitate from the injection water.

A method for separating particles from injection water, the injection water being used for the stimulation of a petroleum reservoir, and the water being drawn from a water reservoir, cleaned and typically treated by means of additives before being led into the petroleum reservoir, characterized in that the water is led into a closed space (14) at the lower portion of the space (14) and out at the upper portion of the space (14), the flow rate within the closed space (14) being sufficiently low for undesired particles to precipitate from the injection water by means of gravitation.
A device for separating particles from injection water, the injection water being used for the stimulation of a petroleum reservoir, and the water being drawn from a water reservoir, the water being cleaned before being led into the petroleum reservoir, characterized in that the water is led into a closed space (14), the cross-sectional area of the space (14) being arranged to make the flow rate of the water low enough for precipitation of undesired particles from the water by means of gravity to take place.
