Operated by Qatar Petroleum, Halul Island is located around 80 kilometres northeast of the city of Doha and serves as the crude oil export terminal for Qatar marine crude oil produced from offshore oilfields. ⠀
In the mid 1950s, with the drastic increase in oil exploration and production in territorial waters around Halul the importance of the island increased and attention was given to its usage as a loading terminal for vessels transporting tools and equipment needed for exploration and drilling operations. In the early 1960s the importance of Halul Island further increased with the start of oil production from the offshore oilfields in Qatar territorial waters close to the island. ⠀
Eventually, Halul became a loading terminal for crude production from those fields. Preliminary infrastructure was developed between 1964 and 1966. The island is hilly, rising to an elevation of 202 feet.
