The seven-year deal is worth more than $250m. It covers the supply of 16 electric motor-driven centrifugal compressors for high-pressure injection applications in the Kauther, Saih Nihayda and Yibal gas fields.

The compressors will be manufactured at GE Oil & Gas facilities in Italy, and will be shipped to Oman over the period of 2009-2015, for a total of 14 projects that will come on line between 2010 and 2016.

In 2007, GE received two contracts from PDO to supply centrifugal compressors for projects in the Saih Rawl gas field and the Harweel oil field in the south of the sultanate.

A gas compressor is a mechanical device used to increase the pressure of gas, thereby making it easier to extract.
