The US Occidental Petroleum Corporation (Oxy) is prequalifying contractors for its phase 5 expansion at the Idd El Shargi North Dome field in Qatar.
Oxy has been operating the offshore oil field since it signed a production sharing agreement with Qatar Petroleum in 1994. The new expansion is expected to sustain the current production of 100,000 barrels-a-day for the next six years.
Contractors are still waiting for this to move forward, but Oxy is taking its time in the prequalification phase, says an oil and gas source based in Qatar. This will be a large offshore job when the tender is finally released, the biggest in Qatar since the Barzan gas field development.
Oxy stated in July that it expects to invest a total of $3bn in upgrading the facilities at the field.
The scope of works will include drilling 200 wells for production, water injection and water source wells, the construction of new platforms and jackets and the installation of fluid processing equipment. Pipeline debottlenecking and water source projects will be executed and several enhanced oil recovery programmes will be initiated.
The Idd El Shargi North Dome field has been in production since 1963 and production had depleted to 20,000 b/d by 1994. Oxy raised production to 140,000 b/d, but this has now levelled off at 100,000 b/d.
