新领域之一为深层“盐下”。目前巴西东部深水区盐下油气勘探主要集中在位于Santa Catarina州和Sa Paulo州海域的桑托斯盆地,盐下勘探活动始于2004年。巴西深水油气盐下开采技术难度大,单井成本高,但由于单井产量高,桶油成本是全球深水作业区中最低的,平均操作成本在10美元/bbl左右,盈亏平衡点在40美元/bbl左右。新领域之二为“超深水区”。这是目前海域油气勘探的又一焦点,主要集中分布于西非海域、墨西哥湾、巴西近海、澳
One of the new areas is deep “under salt.” At present, deep-sea oil and gas exploration in eastern Brazil is mainly concentrated in the Santos Basin located in the waters of Santa Catarina and Sa Paulo states. Exploration activities under salt began in 2004. Due to the difficulty of deep submarine mining technology in deepwater oil and gas in Brazil, the single well costs are high. However, due to the high output of single well, the cost of barrel oil is the lowest in the global deepwater operation area with an average operation cost of around 10 USD / bbl and a break-even point of 40 USD / bbl or so. The second area is “ultra-deep water area”. This is yet another focus of oil and gas exploration in the sea, mainly concentrated in the West African waters, the Gulf of Mexico, offshore Brazil, Australia
