石油设备网讯 据油气杂志3月26日消息称，在收购雪佛龙巴西分公司上游的弗雷德公司后，里约石油公司目前经营着巴西北部Campos盆地的弗雷德油田，这是一个重油和天然气田。
通过这笔交易，里约石油公司将雪佛龙在该特许权中的51.74％股权，加入了其从弗雷德Japao石油公司手中收购18.26%股份的未决协议。弗雷德Japao石油公司是Inpex和Sojitz组建的合资企业。该协议是在2018年10月达成的，需要条件和批准。巴西石油公司持有剩余的30%。
弗雷德油田目前的产量为20000桶/日。所有生产井都有海底完井，并通过立管连接到由特许经营商拥有和运营的弗雷德浮式生产、储存和卸载船，该船可处理多达100000桶/天的液体，可储存150万桶石油。里约石油表示将为该油田的再开发制定计划，包括钻探活动和注水。该公司预计其日产量将增加11000桶，其2P石油储量将增加4300万桶。
该油田位于距离卡波弗里奥125公里，距离波尔沃油田172公里的1128米深的水中，预计可开采石油储量为2-3亿桶。其结构为一个低地势背斜，面积20多平方公里。它有两个主要断块，包含三个叠层储层。第一次生产是在2009年6月。2011年的一次原油泄漏导致勘探活动停止，2012年的一次渗漏导致雪佛龙在2013年4月重启生产之前自愿停产。2014年钻探和注水作业获准恢复。
作为交易的一部分，里约石油公司获得了参与巴西盐矿的权利，其勘探前景可能类似于Roncador油田，深度为4,500米，这可能会被纳入2020年计划的新钻探计划中。
该公司表示，这笔交易包括西拉盆地深水CE-M715区块50%的运营权益。西拉盆地是一个具有石油潜力的新领域。
里约石油公司拥有Polvo油田100%和Manati油田10%的股份。

PetroRio becomes operator of Frade field offshore Brazil
PetroRio SA is now operator of Frade field, a heavy oil and gas field in Brazil’s Northern Campos basin, following the close of its acquisition of Chevron Brasil Upstream Frade Ltda.
With the deal, PetroRio adds Chevron’s 51.74% stake in the concession to its pending agreement to acquire 18.26% from Frade Japao Petroleo, a joint-venture formed by Inpex and Sojitz. That deal, struck in October 2018, is subject to conditions and approvals. Petrobras holds the remaining 30%.
Frade currently produces 20,000 b/d. All producing wells have subsea completion and are connected via risers to the Frade floating production, storage, and offloading vessel—owned and operated by the concessionaires—which has the capacity to process as much as 100,000 b/d of liquids and can store 1.5 million bbl of oil. PetroRio said it will plan for the field’s redevelopment, which could include drilling campaigns and water injections. The company expects its production will increase by 11,000 b/d and 43 million bbl of oil will be added to its 2P reserves.
The field, which lies in 1,128 m of water about 125 km from Cabo Frio and 172 km from Polvo field, holds estimated reserves of 200-300 million bbl of recoverable oil. Its field structure is a low relief anticline spread over 20 sq km. It has two primary fault blocks containing three stacked reservoirs. First production was in June 2009. A crude oil spill stopped exploration in 2011 and a 2012 seep caused Chevron to voluntarily shut production before restarting in April 2013. Drilling and water injection operations were granted permission to resume in 2014.
As part of the deal, PetroRio gains participation in the Brazilian presalt, with the possible exploration of prospects analogous to the discovery in Roncador field, at a depth of 4,500 m, which could be included in new drilling initiatives planned for 2020.
The transaction includes a 50% operating interest in the deepwater CE-M715 block in the Ceara basin, a new frontier with oil potential, the company said.
PetroRio owns stakes in producing fields Polvo 100% and Manati 10%.
