Project Profile
Value: US$290 million
Location: Sindh, Pakistan
Start-up Year: 2003
Gas production: 104,754×106 cu ft (2.9663×109 m3)

Sawan Gas Field is a located in Sindh, Pakistan. A total of 15 wells have been drilled in Sawan Field and 14 are supplying 270×106 cu ft (7,600,000 m3)d gas to Sui Northern Gas Pipelines and 40×106 cu ft (1,100,000 m3)d to Sui Southern Gas Company. The total volume of gas sold from Sawan field during 2009-2010 was 104,754×106 cu ft (2.9663×109 m3) as compared to 123,485×106 cu ft (3.4967×109 m3) during 2008-2009. Sawan is still one of the largest discoveries of gas reserves in Pakistan with proven gas reserves of 1,120 billion cubic feet (BCF).
In November 2001, OMV Pakistan awarded Clough the Phase 1 contract for the engineering, procurement, construction and commissioning (EPCC) of a 170 million standard cubic feet per day (MMSCFD) greenfields gas processing plant. The whole project includes a central processing plant (CPP), a 20 kilometres of 8 inch and 10 inch duplex flowlines linking the production wells to the CPPDesign, the installation of four 240 US gallons per minute (USGM) permanent bore and a water supply pipeline, necessary to meet the plant’s water requirements for the 25 year design life. In July 2002, Clough’s scope of work was expanded when awarded the second phase of the gas field development. The Phase 2 contract included the complete EPCC of a second 170MMSCFD gas processing train, enhanced utilities, and infield flowlines and wellhead facilities for two additional wells.
Gas produced from the Sawan field is fed into the Sui Southern Gas Company Limited distribution grid using the existing Kadanwari to Nawabshah pipeline. A 15 kilometre, 20 inch API 5LX65 tie line was constructed by Clough to link the CPP to the existing pipeline. The tie line was laid through extensive areas of very dry desert sand that posed challenges for the pipeline crew. Clough also designed and constructed 15 accommodation blocks suitable to house up to 140 permanent operations and maintenance staff and contractors.
OMV started full production at the new Sawan gas field in Pakistan on 22nd October 2003. OMV has a stake of 19.74 per cent in Sawan.
