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 (), in which the flow rate is sufficiently low for undesired particles to precipitate from the injection water.
