Abstract
High pressure product fluid from a petroleum well goes into a high pressure separation vessel where preliminary phase separation of the constituents takes place. Oil and gas leave the preliminary separator by a flow line. Power fluid for a triplex pump flows from the high pressure separator into a separator tank that opens to atmosphere. Here, further separation of the phases takes place and power fluid low in abrasive solid content is taken off by a charging pump and fed to the triplex pump. The triplex pump increases the head of the power fluid and introduces it to the well. The power fluid may be either water or oil.
