Qatar Petroleum and Shell Qatar
Qatar Petroleum (QP) and Shell Qatar broke the record for drilling wells in the North Field here using an innovative approach, a senior executive told Offshore Middle East Conference 2010 which opened Tuesday at the Doha Exhibition Centre. Speaking at the opening session, titled Operators Perspectives, Shell Qatar Executive Vice President Andy Brown said, “The 22 wells for Pearl Gas To Liquid (GTL) were drilled in an average time of 45 days, compared to the industry average of 75 days. The fastest well was completed and ready to produce in just 28 days.”
The three-day Offshore Middle East 2010 conference and exhibition, under the patronage of HE Deputy Prime Minister and Minister of Energy and Industry Abdullah bin Hamad Al Attiyah, that officially opens later this evening, is featuring some of the biggest multi-national companies engaged in oil, gas exploration, production, transportation and ancillary industries. Success in the offshore operations in the North Field was achieved using an approach called Simultaneous Operations for the first time in Qatar. Overall the SIMOPs approach saved the State of Qatar and Shell over $46 million in drilling costs, Brown said.
In Simultaneous Operations, or SIMOPS, one well is drilled while perforation, stimulation and clean up operations are simultaneously conducted on a previously drilled well. A redesign of the operations created more space for crew and equipment while the drilling rig was raised around nine storeys higher than normal. This enabled two extra levels of temporary decks to be installed for the extra equipment required for SIMOPs, Brown told the audience comprising decision-makers and professionals from oil, gas and allied industries. The drilling operations, which took six years from when planning began, were completed without a single Lost Time Injury, he said. Brown highlighted the innovations Pearl GTL is bringing to operating the project’s two offshore platforms over the decades ahead. QP and Shell have designed simple platforms, with minimal processing conducted offshore. This enables the platforms to be unmanned in normal operations, controlled by operators sitting over 60kms away in the Pearl GTL control room situated in Ras Laffan Industrial City. Pearl GTL is the world’s largest GTL project and the largest energy project ever launched in Qatar. It will produce liquid fuels, lubricants and chemical feedstocks from natural gas, opening new markets for Qatar’s natural resources. It will also produce significant quantities of natural gas liquids and ethane. Major construction is expected to be complete by the end of 2010, production will start in 2011 reaching full production in 2012. (QNA)
