==History== The company was established as a producer of a modular plant in Tyler, Texas, United States in 1981. It was first listed on the London Stock Exchange in 2005. In 2010, it bought a 20 percent share in the Gateway storage scheme, an undersea cavern for gas storage. In November 2013, Petrofac and the Italian oil firm Bonatti partnered on a $650 million joint venture with Sonatrach to develop new separation and booster compression facilities, extending the life of the Alrar gas field in south-east Algeria. In November 2014, the company issued a profit warning, saying that profit for 2015 would fall by 25%, as slowing demand in China and abundant US output cut the oil price.
