Offshore Filtration Testing and Analysis of Seawater for Oil-Field Injection Available to Purchase

A high rate media-type filter developed for water injection applications has been tested on a 4000 BWPD (barrels of water per day) pilot plant to gather data on water quality achievable on equipment practical for offshore oil production installations. This work has been spread over 13 offshore locations around the world in seven different seas that represent a wide variety of water types, levels of suspended solids, temperatures, and depths.

The test procedures and analytical techniques used on these trials are described together with the filtering characteristics of various seawaters. Analysis included Coulter Counting, core testing, millipore tests, gravimetric, turbidity, and residual chlorine.
