The Queensland Curtis Liquefied Natural Gas (QCLNG) project is the world's first project to convert coal seam gas (CSG) into liquefied natural gas 1 . The project involves drilling thousands of wells in the Surat basin, installing an underground 540 km long pipeline to Gladstone and the building of a plant on Curtis Island to liquefy the natural gas. The project, which has been under construction since 2010, is on schedule to provide LNG for export from the end of 2014.The multi-billion-dollar investment by QGC, the Australian business of BG Group, is one of Australia's largest current capital infrastructure projects. Schlumberger has been contracted to deliver on the drilling and completion phase of this critical project.The "Factory Drilling*" project operates nine rigs using a multidisciplinary team consisting of project management staff utilising/coordinating logistics, warehousing, wellsite management, cementing, wireline, bits, solids control and directional services/personnel. The project has overcome significant challenges in the business development and start-up phases. Through the application of the "excellence in execution" philosophy, records have been broken and new performance benchmarks set in this unconventional CSG market.Since the start of the project in early 2012, using the team's project management abilities and incorporating LEAN (the identification and steady elimination of waste from operations) initiatives, the project has drilled and completed more than 1000 wells, some in as little as 2.15 days (drilling time) and 1.04 days (completion time).The optimisation initiatives have contributed towards reaching a state where the project is currently performing very close to the technical limit, yet challenges are still ahead to maintain and mature the safety culture and improve the operational efficiency even further.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
