Petrochina has invited companies to submit bids for two project management consultancy (PMC) packages on the development of the Halfaya oil and gas field in Iraq.

The two management contracts cover the central processing facility-3 (CPF3) and the gas process plant.

The state-owned Chinese group has set deadlines of 19 October for proposals to be submitted on both packages.

Phase three of the Halfaya project is planned to increase the field’s production capacity to 535,000 barrels a day (b/d) by 2017 with the construction of the main facilities and a gas processing plant.

Petrochina and its partners plan to double the field’s production to 200,000 b/d, from 100,000 b/d currently, with the Halfaya export pipeline due to be completed in 2014 and the phase-two central processing facilities (CPF) expected to be commissioned in 2015.

The Halfaya consortium includes Petrochina’s parent group China National Petroleum Corporation (CNPC), Malaysia-based Petronas, France’s Total and state-owned Missan Oil Company.

In December 2013, UK-based Mott MacDonald was awarded a new contract to provide technical support for the second and third phases of development at Halfaya. The company had already completed work on the first phase of the development.
