Petrofac preparing to tender Qatar gas sweetening civil works

07 April 2010

Qatar Petroleum projects are at Mesaieed and Dukhan

The UK’s Petrofac has begun soliciting interest from contractors for the civil works subcontract for its planned gas processing facilities in Qatar.

The company expects to tender the contract in June. Initial estimates for the civil works packages put the value at more than $100m with the project spread across two sites, at Dukhan and Mesaieed.

Petrofac won the estimated $650m contract to upgrade state-run Qatar Petroleum’s (QP) gas processing facilities at the sites on 29 March (MEED 29:3:10).

The scheme includes the construction of a 750 million-cubic-feet-day (cf/d) acid-gas removal unit and amine-sweetening plant at Mesaieed. QP already has two operational units at the North field processing plant in Mesaieed. The gas from the plant will primarily be used as feedstock for petrochemicals plant planned for Mesaieed.

A second acid-gas removal unit will be built at the onshore Dukhan field, with the capacity to process 450 million cf/d of gas from the Khuff reservoir, which is part of the field.

The Dukhan field contains three oil reservoirs, and a fourth non-associated gas reservoir. The Khuff reservoir is one of four sour-gas sources supplying Qatar’s industrial consumers. The plants will remove sulphur from the gas to meet environmental regulations and industrial gas specifications on sulphur content of 4-25 parts per million to reduce emissions.

“The immediate focus for Qatar Petroleum (QP) at the moment is the shutdown which they have awarded to [local] QCon”, says a source close to the project. This is expected to be completed by 15 April.
