据Splash 4月21日消息，巴国油和Equinor已开始生产Roncador提高石油采收率(IOR)项目的头两口井。Roncador油田位于巴西海岸的Campos盆地，自1999年开始投产，是该国第五大产油资产。巴国油是该项目的运营商，拥有该油田75%的股权；Equinor拥有25%的股份。
这两口井是一系列IOR井中第一口达到生产的井。启动时间比计划提前了近五个月，成本仅为计划成本的一半。这些油井每天为Roncador增加约2万桶石油当量，使日产量达到约15万桶，并降低了该油田的碳强度（每桶生产的排放量）。
通过第一个IOR项目，该合作伙伴将钻探18口井，预计将提供1.6亿桶的额外可采资源。油井设计的改进和合作伙伴的综合技术经验是前六口井成本降低50%的主要驱动力，其中包括生产中的两口井。
除了计划中的18口IOR井外，该合作伙伴认为，它可以进一步提高采收率，旨在将可采资源量增加10亿桶石油当量。该油田现有的石油当量超过100亿桶，许可证有效期至2052年。战略联盟协议还包括Roncador的能源效率和二氧化碳减排计划。

Petrobras and Equinor start production at IOR project
Petrobras and Equinor have started production from the first two wells of the increased oil recovery (IOR) project at Roncador. Located in the Campos Basin off the coast of Brazil, the Roncador oil field is the country’s fifth-largest producing asset and has been in production since 1999. Petrobras is operator on the project and has 75% equity in the field; Equinor has 25%.
The two wells are the first of a series of IOR wells to reach production. Startup is almost five months ahead of schedule and at half of the planned cost. The wells add approximately a combined 20,000 barrels of oil equivalent per day to Roncador, bringing daily production to approximately 150,000 barrels and reducing the carbon intensity (emissions per barrel produced) of the field.
Through this first IOR project, the partnership will drill 18 wells, which are expected to provide additional recoverable resources of 160m barrels. Improvements in well design and the partners’ combined technological experience are the main drivers behind the 50% cost reduction across the first six wells, including the two in production.
In addition to the planned 18 IOR wells, the partnership believes it can improve recovery further and aims to increase recoverable resources by a total of 1bn barrels of oil equivalent. The field has more than 10bn barrels of oil equivalent in place, under a licence lasting until 2052. The strategic alliance agreement also includes an energy efficiency and CO2 emissions-reduction program for Roncador.
