The Source Qatar's North Field
Qatar was gifted with a strategic geographical location that placed it in the heart of the largest offshore non-associated gas field in the world, the North Field.
The North Field is believed to be the most significant natural gas reserve in the world for the production of LNG , capable of comfortably supplying multiple large-scale renewable gas sales contracts for many decades.
The Qatari North Field
Discovered in the early 1970s, the Qatari North Field currently has estimated reserves of more than 900 trillion standard cubic feet of recoverable gas. The field covers a total 6,000 square kilometres and extends from slightly onshore to continue all the way north to the three contract areas, i.e. RasGas (RG), Qatargas (QG) and North Field Alpha (NFA).
Development of the North Field commenced in 1991 with the NFA complex, operated by Qatar Petroleum. Prior to 1991 and after a number of appraisal wells were drilled to quantify the reservoir's gas accumulation, delineate its extension, and determine the reservoir fluid and the geological characteristics of the field. The reservoir at the North Field is the Khuff formation.
Within the main Khuff gas-bearing reservoir, four Khuff zones were defined. Of the four zones, K-4 is the most prolific and contains approximately 60 per cent of the gas reserves. The offshore contract locations within the North Field are known as the 'North Contract Location' and the gas-bearing reservoir from which RasGas and RasGas (II) extract petroleum products lies entirely offshore.
