WThe Bouri Offshore Field is part of Block NC-41, which is located 120 kilometers (75 mi) north of the Libyan coast in the Mediterranean Sea. It was first discovered in 1976 at a depth of 8,700 feet (2,700 m) and is estimated to contain 4.5 billion barrels (720,000,000 m3) in proven recoverable crude oil reserves and 3.5 trillion cubic feet (99 km3) of associated natural gas with an annual production potential of 6 billion m³. Bouri is considered the largest producing oilfield in the Mediterranean.
WThe El Sharara oil field is an oil field located in Murzuq Desert. It was discovered in 1980 and developed by Petrom. The oil field is operated and owned by Repsol. The total proven reserves of the El Sharara oil field are 3 billion barrels (403×106tonnes), and production is centered on 300,000 barrels per day (48,000 m3/d).
WNC186 is an oil field located in the southwest of Ubari, Libya. It operated by Repsol.
WThe Raguba field is an oil field located in the central part of Libya's Sirte Basin in Concession 20. The Sirte Oil Company (SOC) operates the Raguba field. The field is connected by pipeline to the main line between the Nasser field, one of the largest in Libya, and Brega. Raguba field has 80 wells producing high gravity (43 °API) oil. The first exploration oil well in this field was drilled in January 1961 with production commencing in 1963. By the end of 2005, the field had produced 787 million standard barrels of oil and 859×10^9 cu ft (2.43×1010 m3) of associated gas.
WThe Sarir Field was discovered in southern Cyrenaica during 1961 and is considered to be the largest oil field in Libya, with estimated oil reserves of 12 Gbbl (1.9 km3). Sarir is operated by the Arabian Gulf Oil Company (AGOCO), a subsidiary of the state-owned National Oil Corporation (NOC).
WWaha field is an oil field located in the Libya sirte basin and owned by the Waha Oil Company (WOC), which is a subsidiary of the National Oil Corporation (NOC). During 2006, the Waha fields produced around 350,000 barrels (56,000 m3) per day, down from around 1 Mbbl/d (160,000 m3/d) in 1969 and 400,000 bbl/d (64,000 m3/d) in 1986. However, WOC expects to increase Waha output by around 200,000 bbl/d (32,000 m3/d) over the next couple of years. In 2005, ConocoPhillips and co-venturers reached an agreement with NOC to both return to its operations in Libya and to extend the Waha concession by another 25 years. ConocoPhillips operates the Waha fields with a 16.33% share in the project. NOC has the largest share of the Waha concession at 59.17%, and additional partners include Marathon Oil (16.33%), and Amerada Hess (8.17%). The Waha oil field was captured by ISIS soldiers on March 5th 2015 but has since been recaptured.
WThe Zelten oil field is located at the foot of the Zelten Mountains, about 169 kilometres (105 mi) south of Brega in Concession 6. Zelten holds the title as the largest oil field in the Gulf of Sidra. The 229 wells in Zelten use a gas lifting system. The Zelten oil field is not associated with the town Zelten, which is located in the North-West of Libya.
