The Harding oilfield is a small oil field operated by TAQA, in the North Sea block 9/23b, approximately 200 miles (320 km) North-East of Aberdeen and in 110 metres (360 ft) of water.

[1] The field was discovered in 1987, when oil was found in Eocene at a depth of 1,850 metres (6,070 ft).

[2] The abundance of naphthenic acid in the oil however made the development unattractive at the time.

The crude is heavy and naphthenic and is generally of a lower value compared to other North Sea oils.

The selected development solution was a heavy-duty steel jack-up production unit based on a proprietary design by Technip Geoproduction resting on a concrete gravity base which had storage for 550,000 barrels (87,000 m3) of oil.

The project is being recycled and in 2018 TAQA was in discussion with its then partner, Maersk Oil, to investigate alternative development options for the gas resources in the area.
