A schematic drawing of the Ekofisk Phillips Norway Group plant shows the various steps to gas reinjection. The first commercial crude oil is being produced from this newly discovered giant North Sea oil field. During the second half of 1973, a complete gas separation plant and a reinjection plant will be placed in operation making it possible to recover all of the condensate from the casing-head accessory gas and at the same time it will help to conserve the remaining natural gas by reinjecting it back into the producing zone. All compression equipment, 6 units totalling 110,000 hp and consisting of multistage centrifugal compressors, are driven by gas turbines. The discharge pressure of the 2 reinjection compressors, 9,200 psig, represents a record high at the moment for centrifugal compressors. The development of these special high pressure centrifugal compressors was necessary to fill the need for relatively lightweight, compact equipment in order to keep the cost of the supporting, deep water, underwater structure to a minimum. The design criteria for the equipment are given.
