Brent Crude may refer to any or all of the components of the Brent Complex, a physically and financially traded oil market based around the North Sea of Northwest Europe; colloquially, Brent Crude usually refers to the price of the ICE Brent Crude Oil futures contract or the contract itself. The original Brent Crude referred to a trading classification of sweetlight crude oil first extracted from the Brent oilfield in the North Sea in 1976.[1] As production from the Brent oilfield declined over time, crude oil blends from other oil fields have been added to the trade classification. The current Brent blend consists of crude oil produced from the Brent, Forties (added 2002), Oseberg (added 2002), Ekofisk (added 2007), and Troll (added 2018) oil fields (also known as the BFOET Quotation).[2]
The Brent Crude oil marker is also known as Brent Blend, London Brent and Brent petroleum. This grade is described as light because of its relatively low density, and sweet because of its low sulphur content.
Brent is the leading global price benchmark for Atlantic basin crude oils. It is used to set the price of two-thirds of the world’s internationally traded crude oil supplies. It is one of the two main benchmark prices for purchases of oil worldwide, the other being West Texas

An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign state has special rights regarding the exploration and use of marine resources, including energy production from water and wind.[1] It stretches from the baseline out to 200 nautical miles (nmi) from the coast of the state in question. It is also referred to as a maritime continental margin and, in colloquial usage, may include the continental shelf. The term does not include either the territorial sea or the continental shelf beyond the 200 nautical mile limit. The difference between the territorial sea and the exclusive economic zone is that the first confers full sovereignty over the waters, whereas the second is merely a “sovereign right" which refers to the coastal state’s rights below the surface of the sea. The surface waters, as can be seen in the map, are international waters.     quoted from Wikipedia

Subi Reef, also known as Zamora Reef (Tagalog: Bahura ng Zamora, lit. ’Reef of Zamora‘); Zhubi Reef (Mandarin Chinese: 渚碧礁; pinyin: Zhǔbì Jiāo); Vietnamese: đá Xu Bi, is a reef in the Spratly Islands of the South China Sea located 26 km (16 mi) southwest of Philippines‘ Pag-asa island Thitu Island under the municipality of the Kalayaan Island Group, Palawan province. It is illegally-occupied by China (PRC), and claimed by Taiwan (ROC) and Vietnam. According to the claims of the PRC, it currently falls under the de facto jurisdiction of Nansha islands, Sansha city, Hainan province, China. But under the clauses of the UNCLOS, which the PRC is also a signatory, the international law (if applied) only the Philippines has the maritime rights to exploit its resources or build structures, as it is within the continental shelf (“Extended Continental Shelf“) of the coastal country.   from Wikipedia
