RasGas has announced that it has completed offshore drilling of 30 development wells for the US$10.3bn Barzan Gas Project in Qatar
According to the company, this will pave the way for subsequent phases of the project to proceed with connecting the wells to subsea pipelines that will take gas to shore.
The wells — spread over three offshore wellhead platforms — have a total length of approximately 138 km and reach more than 3,000 metres below the sea’s surface.
The Barzan offshore drilling operations required three jack-up drilling rigs working for a combined total of 4,740 days.
Dave Frye, chief subsurface and technology officer of RasGas, said “Highly sophisticated drilling technologies and techniques such as a pressurized mud cap drilling technique were successfully employed to address unique technical challenges allowing the wells to be drilled safely and efficiently.
When in operation, RasGas’ facilities of liquefied natural gas and pipeline sales gas will have a total production capacity of around 311mn standard cubic metres of gas per day, company sources said.
Nafez Bseiso, RasGas’ chief venture officer, said that the completion of the offshore drilling took the country’s landmark energy project one step closer to completion.
“Construction of Barzan Gas Project onshore facilities recently surpassed the 50 per cent completion mark. The next significant step will be to connect the project pipelines running from Ras Laffan to the wells located 80 km off the coast of Qatar.”
RasGas was appointed by shareholders — Qatar Petroleum and ExxonMobil — to execute the Barzan Gas Project and operate the facilities, one of the largest and technologically advanced gas processing plants in the region.
