The K14-K18 gas fields are significant natural gas producing areas in the Netherlands sector of the North Sea, about 120 km north west of Den Helder. These five contiguous fields started producing gas in 1977 and are still operational.
The K14-K18 gas fields are located in the Southern North Sea. They extend over the Netherlands Offshore Blocks K14, K15, K16, K17 and K18. The gas reservoirs have the following properties: [1][2][3]
