The State of Qatar has developed into the largest LNG supplier in the world in a span of 15- 20 years after a strategic decision to develop the North Field. The journey has seen the development of 14 LNG trains over this period with application of cutting edge technologies, evolving during this period. This has not only helped to build bigger and efficient facilities, but has also contributed in this development at unprecedented pace. The fundamentals of "lessons learned" have been effectively applied during this period to continuously improve, by either optimizing the selected technology or upgrading to the new technologies.
The utilization and application of new technology has been consistent throughout the "wells to wheels" concept. It started from strategic location of well bores to facilitate maximum recovery at sustained production levels and ensure sound life cycle reservoir management practices. The implementation of "Fast Drill" concept and OBB (Optimized Big Bore) resulted in significant capital cost savings. Additionally, the OBB wells also ensured increased production capacity per well. Transition from dry-gas (offshore dehydration) to wet gas concept was successfully implemented and more than 80% of LNG production is now achieved by wet gas transportation from offshore pipelines. Wet gas concept also introduced new chemicals for managing the hydrate and corrosion concerns. The receiving onshore gradually upgraded the technology in various projects. The sulphur recovery processes was changed from Sulfinol based to Ucarsol/Selexol process combination. The split MR compression process was introduced from Ras Gas Tr-3 onwards, improving the efficiency of liquefaction system. APx process in main cryogenic liquefaction process was introduced for the Mega trains in Ras Gas and Qatar Gas. The transportation of LNG plays a key role in delivering the product to the customers. Technology development resulted in almost doubling the carrying capacity from conventional tankers to Q-flex and Q-max ships.
In summary, the role of technology and the State's willingness to apply it, has resulted in Qatar being the largest LNG producer in the world.
