Pentair’s UF membranes selected for pretreatment duties on Kraken FPSO

The FPSO, from Malaysia’s Bumi Armada, is designed to process up to 460 000 bpd and has a storage capacity of up to 80 000 bpd of oil and 20 MMscf of gas. Seawater injection is at a rate of a maximum of 275 000 bpd.

Using the X-Flow UF membranes as the pretreatment solution rather than conventional pretreatment options, such as multimedia filtration followed by disposable cartridge filters, provides lower life-cycle costs, a smaller footprint and lower installed weight, and improved performance of the downstream sulphate removal membranes.

The Kraken field is one of the largest subsea heavy-oil field projects under development in the UK section of the North Sea. Kraken could have reserves of 137 million barrels of heavy oil, with an estimated field life of 25 years. At its peak, it is expected to produce over 50 000 barrels per day (bpd).

“This order confirms again the suitability of Pentair’s X-Flow brand of UF membranes for offshore seawater treatment and we are committed to support the important water treatment needs of our oilfield customers,” said Eric Leegwater, Pentair’s business development manager for Oil and Gas.
