NC186 is an oil field located in the southwest of Ubari, Libya. It is operated by Repsol.
The oilfield is located in the Murzuq Basin, immediately to the northeast of Repsol's NC115 acreage. It forms part of the El Sharara.
In November 2005, Repsol announced, in a statement to the Madrid stock exchange, a new oil well with an estimated production capacity of 4,650 barrels per day at block NC186 "in the prolific basin of Murzuq". Repsol said the find was discovered just 16 kilometres to the north of the last find in the same block at the start of October.[1]
The economy of Libya depends primarily on revenues from the petroleum sector, which represents over 95% of export earnings and 60% of GDP. These oil revenues and a small population have given Libya one of the highest nominal per capita GDP in Africa.

It is led by Farhat Bengdara, appointed in July 2022, he is seen by many experts as the glue holding east and west together. Of NOC's subsidiaries, the largest oil producer is the Waha Oil Company (WOC), followed by the Arabian Gulf Oil Company (Agoco), Zueitina Oil Company (ZOC), and Sirte Oil Company (SOC).
Sirte Oil Company (SOC) is an oil and gas company in Libya operating under the state-owned National Oil Corporation (NOC). The company is located in Brega SOC’s operations include oil and gas exploration and production (E&P) and manufacturing.
The 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.
The Elephant Field is an oil field located in onshore in Libya's Murzuq Basin.
The 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.
The Sirte Basin is a late Mesozoic and Cenozoic triple junction continental rift along northern Africa that was initiated during the late Jurassic Period. It borders a relatively stable Paleozoic craton and cratonic sag basins along its southern margins. The province extends offshore into the Mediterranean Sea, with the northern boundary drawn at the 2,000 meter (m) bathymetric contour. It borders in the north on the Gulf of Sidra and extends south into northern Chad.

Yme is an oil field in the Egersund basin area in the central part of the North Sea. It is located 160 kilometres (99 mi) northeast of the Ekofisk oil field. The water depth is 93 metres (305 ft). The field was discovered in 1987 and was developed by Statoil with production from 1996 to 2001. In 2001 low oil prices led to the abandonment of the field. After the production license was relinquished by Statoil, a new license group led by Talisman Energy was formed to redevelop the field. In 2007 Talisman was granted permission to redevelop the field. The redevelopment was unsuccessful and the newly installed Yme MOPU STOR was abandoned and decommissioned without having entered production. A new attempt called the Yme New Development was launched by the new operator Repsol, which involved reusing the subsea installations already in place. The Yme field began producing again in 2021, marking the first time that a previously abandoned Norwegian oil field has been restarted.
Oil reserves in Libya are the largest in Africa, and among the ten largest oil reserves globally with 46.4 billion barrels of proven oil reserves as of 2010. Oil production was 1.65 million barrels per day as of 2010, giving Libya 77 years of reserves at current production rates if no new reserves were to be found. Libya is considered a highly attractive oil area due to its low cost of oil production, low sulfur content, being classified as "sweet crude" and in its proximity to European markets. Libya's challenge is maintaining production at mature fields, while finding and developing new oil fields. Most of Libya remains under-explored as a result of past sanctions and disagreements with foreign oil companies.
Estimates of total oil reserves in Cuba are varied, and depend mainly on estimations of undiscovered offshore deposits in the North Cuba Basin. Proved crude oil reserves were 124 million barrels as of 2013.

In late January 2019, the Libyan National Army (LNA) led by Marshal Khalifa Haftar launched an offensive to take control of the city of Sabha and the rest of southern Libya from the internationally recognised Government of National Accord (GNA) and local factions. Officially, the LNA announced that the reason for the operation was to remove terrorists, Chadian rebel groups, and to secure the border, but it has expanded Haftar's territorial control and acquired him oil fields near Sabha. It has also restarted some interethnic conflicts as the LNA has allied with local Arab tribes, while the Tuareg and Toubou tribal militias are loyal to the GNA.
