Doha / QATAR: RasGas has safely and successfully completed offshore drilling for 30 development wells for the $10.3bn Barzan Gas project.

This would pave the way for subsequent phases of the project to proceed with connecting the wells to subsea pipelines that will take gas to shore, said RasGas, which was appointed by shareholders Qatar Petroleum and ExxonMobil, to execute the project and operate the facilities.

The complex Barzan offshore drilling operations required three jackup drilling rigs working for a combined total of 4,740 days and involving more than 300 employees at any given time working in challenging offshore conditions, it said. The 30 development wells – spread over three offshore wellhead platforms – have a total length of approximately 138km and reach more than 3,000m below the sea’s surface.

When the two trains are in operation, RasGas’ facilities (liquefied natural gas and pipeline sales gas) will have a total production capacity of around 11bn standard cubic feet of gas per day (equivalent to almost 2mn barrels of oil per day), making it one of the world’s largest single gas processor.

“Highly sophisticated drilling technologies and techniques such as a pressurised mud cap drilling technique were successfully employed to address unique technical challenges allowing the wells to be drilled safely and efficiently,” according to Dave Frye, chief subsurface and technology officer. Nafez Bseiso, RasGas chief venture officer, said completion of the offshore drilling takes the country’s landmark energy project one step closer to completion.

Highlighting that the construction of Barzan Gas Project onshore facilities recently surpassed the 50% completion mark, he said “the next significant step will be to connect the project pipelines running from Ras Laffan to the wells located 80km off the coast of Qatar.”

As of July, the venture project team reached an unprecedented 78mn hours worked without a lost time incident (LTI), at a rate of over 1.5mn work-hours per week. This LTI milestone achievement surpasses all previous performance in Qatar.
