Gulf-Times: New Qatargas projects ‘well on track’ – Shell

DOHA: The offshore works relating to Qatargas 3 and 4 projects are “right on track”, Shell has said.
Qatargas 3 and Qatargas 4 comprise two mega trains of 7.8mn tonnes per year (tpy) annual capacity each.

Qatar Petroleum and Shell are shareholders in Qatargas 4 while QP, ConocoPhillips and Mitsui are shareholders in Qatargas 3.

To leverage the benefits and economies of scale by working together and share technological know-how and expertise, the development of the majority of the facilities for the two ventures has been brought under the management of a single Joint Asset Development Team (JADT), says a report in the latest issue of “Shell in the Middle East

Ken Marnoch, deputy chief operating officer Qatargas 3 & 4 JADT, said the project began operations in November 2004 by spudding an appraisal well for Qatargas 3. In June 2005, Qatargas 3 and Qatargas 4 came together as an integrated project and in August that year personnel from Qatargas, Shell and ConocoPhillips began working together as a single team.

“Each of the two LNG trains will produce 7.8mn tpy and will need to be supplied with 1.4bn standard cubic feet per day (scfd) of gas each. To do this we have under construction, three production platforms, each with a capacity for 15 wells,” Marnoch said.

He said some three jackets (support legs) on which the production platforms will be installed, are in place. The production platforms are currently being built in Jebel Ali near Dubai and will be ready for installation and hooked up to the pipelines and wells by the year-end.

“At the moment we have three rigs, one for each jacket, drilling development wells. These wells were expected to deliver around 85,000scfd of gas on average with the wells being designed to produce a maximum of 150,000scfd of gas, if required.

“So far we have drilled and completed six of the 33 wells and are using a batch drilling process, where we drill the same hole size on several wells rather than drilling and completing one well at a time,” he said.
According to Marnoch there had not been a single lost time incident (LTI) since the Joint Asset Development Team began operations in November 2004 in 3.5mn man hours of drilling.

“We continue to make good progress offshore but the great news is that everyone is going home safe” he said. He said, “This project has a strong safety culture with everyone in the upstream team playing their part. “While we continue to demonstrate that it is possible to be incident and injury-free, we know our past performance is no guarantee for future. Our focus for 2008 is to engage with more people to build, strengthen and deepen our relationships as our safety bottom line is about people.”
