中国石化新闻网讯 据普氏能源资讯里约热内卢10月26日消息称，巴西石油公司周五表示，由巴西国家石油公司、英国石油公司和中国石油天然气集团公司组成的财团已开始在巴西Peroba盐下海域钻探首口油井。
该集团于2017年10月在巴西第三次盐下储层产量分成拍卖期间收购了该地区。
巴西国家石油公司(Petrobras)在一份声明中表示“Peroba是2017年和2018年在产量分成机制下收购的七个区块中开始钻探的第一个。”
在开始钻探之前，巴西国家石油公司(Petrobras)的腐败丑闻和油价暴跌导致勘探活动停滞数年，随后出现了一波收购地震活动的浪潮，这是勘探活动首次取得具体进展。过去两年，巴西石油公司与英国石油公司、挪威石油公司、埃克森美孚、壳牌和道达尔一道在巴西大规模重新开放油田期间，重振陆上和海上油气田的投资组合。
Peroba被认为是盐下产量分成拍卖中最受欢迎的区域之一，这引发了三家独立财团的激烈竞标。巴西国家石油公司拥有该油田40％的运营股份，而BP持有40％的股份，中国石油天然气集团公司(CNPC)持有20%的股份。该集团支付了20亿雷亚尔（6.3亿美元）的签约奖金，并保证政府76.96％的利润份额以赢得Peroba的开发权。
巴西国家石油管理局估计该区块的石油储量高达53亿桶，而咨询公司IHS Markit估计该区域可采储量可达10亿桶。
Peroba位于里约热内卢州离岸约300公里处。巴西国家石油公司称，该区块面积近1100平方公里，水深2100-2600米。它夹在北面的卢拉油田和西部的萨皮霍油田之间。卢拉和萨皮霍是巴西两大石油和天然气生产商。
巴西国家石油公司说：“靠近这些油田的位置是盐下产量最高的油田之一，这表明该地区具有巨大的潜力，”
自2017年底以来，巴西共进行了6次单独的许可销售，其中包括9月底的第五次盐下产量分成拍卖，此前改革工作设定了年度投标的固定日程，开放了根据产量分成合同出售的海底石油田由国际石油公司运营和减少在勘探和开发中使用当地生产的商品和服务的要求。预计到2020年中期，巴西的原油日产量将从目前的300万桶增加到550万桶。。
巴西国家石油公司仍然是盐下最大的利益相关者，但通过与业内几家顶级公司战略合作来摆脱政府干预分担风险，公司转变了政策。降低风险的举措包括将新土地的运营控制权让给挪威国家石油公司、埃克森美孚和道达尔，以换取少数股权。。
巴西国家石油公司表示，该公司总共收购了21个新的勘探区块，涉及产量分成和特许权销售。
巴西国家石油公司在谈到近期的收购时表示：“这些新项目有助于加强巴西国家石油公司的勘探组合，确保公司未来生产的可持续性。”

Petrobras-led group drills first well in Peroba subsalt area
A consortium of Petrobras, BP Energy and CNPC has started drilling its first well in the offshore Brazil Peroba subsalt area, Petrobras said Friday.
The group acquired the area during Brazil's third subsalt production-sharing auction in October 2017.
"Peroba is the first of seven blocks acquired in 2017 and 2018 under the production-sharing regime to start drilling," state-led Petrobras said in a statement.
The start of drilling followed a wave of seismic-acquisition activity that represented the first concrete advance in exploration activity after several years of stagnation caused by a corruption scandal at Petrobras and the collapse in oil prices. Petrobras was joined by BP, Norway's Equinor, ExxonMobil, Shell and Total in revitalizing portfolios of onshore and offshore acreage during a grand reopening of Brazil's oil patch over the past two years.
Peroba was considered one of the top areas available during the subsalt production-sharing auction, which triggered heated bidding from three separate consortia. Petrobras owns a 40% operating stake in the field, while BP has 40% and CNPC has 20%. The group paid a signing bonus of Real 2 billion ($630 million) and guaranteed the government 76.96% share of profit oil to win development rights to Peroba.
Brazil's National Petroleum Agency has estimated the block held up to 5.3 billion barrels of oil in place, while consultants group IHS Markit estimated the region could hold up to 1 billion barrels of recoverable reserves.
Peroba is located about 300 kilometers offshore Rio de Janeiro state. The block comprises an area of nearly 1,100 square kilometers, with water depths at 2,100-2,600 meters, Petrobras said. It is sandwiched between the Lula Field to the north and the Sapinhoa Field to the west. Lula and Sapinhoa are Brazil's two biggest oil and natural gas producers.
"The location close to these fields, which are among the most productive in the subsalt, indicates the high potential of the area," Petrobras said.
Brazil held six separate licensing sales since late 2017, including the fifth subsalt production-sharing auction in late September, after reform efforts set a fixed calendar for annual bid rounds, opened subsalt fields sold under production-sharing contracts to operation by international oil companies and reduced requirements to use locally produced goods and services in exploration and development. The sales are expected to drive Brazil's crude oil production to 5.5 million b/d by the mid-2020s, up from about 3 million b/d currently.
Petrobras remains the biggest stakeholder in the subsalt, but shifted company policy amid newfound freedom from government meddling to share risk via strategic partnerships with several of the industry's top players. The move to reduce risk included ceding operational control of fresh acreage to Equinor, ExxonMobil and Total, for example, in favor of minority stakes.
In total, Petrobras acquired stakes in 21 new exploration blocks across the production-sharing and concession sales, the company said.
"These new projects contribute to the strengthening of Petrobras' exploration portfolio, ensuring the sustainability of the company's future production," Petrobras said of its recent purchases.?
