[WORLDKINGS] World Tops Academy – Top 5 largest offshore oil fields in the world


(WorldKings.org) Oil and gas companies invest heavily in developing oil fields to meet the world’s growing demand for energy. This is top 5 largest offshore oil fields in the world.

1. Marjan Complex- 17,238,800,384 boe



The Marjan Complex, located off Saudi Arabia’s east coast, is comprised of the Marjan, Maharah, Lawhah and Hamur offshore fields. The field is operated by Saudi Aramco, the world leader in oil production and one of the largest and most profitable companies in the world.

With remaining reserves of over 17.2 billion barrels of oil equivalent (BBOe), the Marjan Complex is the field with the largest reserves in the world. These remaining resources are comprised of 15,623.71 million barrels (MMbbl) of liquid reserves and 9,747.96 billion cubic feet (Bcf) of natural gas reserves. Production at the field is at about 50,000 barrels of oil equivalent per day (boepd).

Saudi Aramco has continued to develop the Marjan Complex, awarding engineering contracts in September 2018 and February 2019 for the company’s largest upstream development project in 2019.

2. Safaniya – 17,136,224,734 boe



The Safaniya field is also owned by Saudi Aramco and is located 200km north of the city of Dhahran in the Persian Gulf. Safaniya was discovered in 1951 and has been in production since 1957. It is operated with more than 624 production wells and a series of different platforms.

While the Safaniya field is the second-largest offshore oil field by remaining reserves with over 17.1 BBOe, it is the world’s largest field by recoverable resources with 37 billion barrels of oil reserves and 5,360 billion cubic feet of natural gas.

3. North Field Expansion- 11,509,802,413 boe



The North Field Expansion located offshore Qatar is anticipated to come online in 2023, peaking at 4600.0 MMcfd by 2045 with a projected field life of 58 years. Qatar Petroleum is the operator of the field, with 100% operating interest in the expansion project.

The North Field Expansion is the third-largest field by remaining resources, with total recoverable reserves of over 11.5 BBOe. These resources are comprised of 2,083.24 MMbbl of liquid reserves and 56,554.84 Bcf of natural gas reserves. Located off the north-east shore of the Qatar peninsula and encompassing an area of around 6,000km2, the North Field is one of the largest non-associated natural gas fields in the world.

4. Zuluf – 11,366,711,770 boe



The Zuluf field is another Saudi Aramco-owned project, located approximately 40km off Saudi Arabia’s northeast coast in about 40 metres of water. Zuluf has yet to reach the midpoint of its field life, having recovered 34% of its total recoverable reserves. The field has remaining reserves of over 11.3 BBOe, comprised of 11,072.35 MMbbl of liquid reserves and 1,766.64 bcf of natural gas reserves. Total production at the Zuluf field is around 764 boepd.

Saudi Aramco announced a major expansion to develop Zuluf’s heavier crude reservoirs in November 2017. It is expected to add 600,000 bopd of heavy crude oil to Saudi Aramco’s operations by 2023.

5. Upper Zakum – 11,064,572,697 boe



Located approximately 84km off the north-west shore of Abu Dhabi, the Upper Zakum oil field is the world’s second-largest offshore oil field in the world by recoverable resources and the fifth-largest by remaining reserves.

The current production capacity of the field is about 728,000 barrels of crude per day. The Upper Zakum field has recovered 33.4% of its 16 BBOe recoverable resources, with remaining reserves of just over 11 BBOe. Expansions for the field over the next few years are expected to increase Upper Zakum’s production capacity to 750 boepd, eventually increasing further to one million boepd by 2024.
