The L10 gas field is a major natural gas producing field and hub in the Netherlands sector of the North Sea, about 65 km west of Den Helder. The field started producing gas in 1976 and was still operational in 2021.

at a depth of 3,772 to 3,800 metres. The properties of the gas are:
Development
The L10 gas reservoir was developed by a number of offshore installations across the L10 Block. The L10-A complex is the hub of the field, it receives gas from its bridge-linked riser platform, from L Block satellite platforms, and from the adjacent Block 12.
The L10-A complex also receives gas from K12-C/CC, K12-D, K12-G and K12-K platforms.
Gas from the field is transported through the 178 km, 36-inch diameter Noordgastransport pipeline from the L10-A Complex to

Decommissioning
In June 2020 Neptune Energy announced that it had decommissioned three platforms in the L10 Field. These were the satellite platforms L10-C, L10-D and L10-G.
In December 2020 Neptune Energy began a feasibility study into whether depleted gas fields near L10-A, L10-B and L10-E could be used to sequester carbon dioxide. The capacity of the reservoirs is around 120-150 million tonnes of CO
2 and the annual injection rate would be about 5-8 million tonnes per year.
