油气开发项目开始在欧洲、亚洲、中东和非洲启动。在今年前几个月,全球范围内的石油企业开发项目发展迅速,在欧洲、中东和非洲地区有相当大的增长。预计在不久的将来,中东和非洲会有一些额外的项目,东亚地区最近也蓄势待发,预计将在年底前实现增产。
道达尔在欧洲设得兰群岛西部的Laggan-Tormore油气田项目计划生产9万桶/天石油当量的天然气(Laggan Tormore是位于设得兰群岛以西的一个深水天然气项目,日产量9万桶石油当量,大约为英国总产量的6%)。尽管Laggan-Tormore项目最初预期在2014年底投产,在未来总产量增长中起着至关重要的作用,但该项目多次被推迟投产。位于水下1968英尺的Laggan-Tormore天然气和凝析气田拥有四个水下气井,通过86英里连接设得兰天然气厂,该厂具有5亿立方英尺/天的天然气处理能力。石油圈原创,石油圈公众号:oilsns
英国石油和天然气首席执行官,在今年二月份的一份声明中强调了该油田项目将会给英国油气行业带来的好处。她说,“对于英国石油和天然气行业来说,在这个充满挑战的时期,Laggan-Tormore项目工业油流的首次出现是一个可喜可贺的消息(工业油流是是在目前的经济、技术条件下,一口井具有开发价值的最低油气产量标准,即工业油井试油稳定日产量超过规定下限的标准)。此气田的开发给英国吸引了数十亿英镑的投资,解决了成千上万人的就业问题,但仍需要数年的技术革新。此气田的产量将供应英国天然气需求,并且会占据很大的比重。英国长期将天然气作为燃料也是从行动上支持了能源安全”。
二月份另一个欧洲油气开发项目在英国威尔德盆地的Horse Hill-1油田启动。起初油井以超过700桶/天的产量生产,油水各占一半,稳定后以超过463桶/天的产量生产,其中有99%的油和不超过1%的水。Horse Hi ll-1油井以超过456桶/天产量稳定生产API为40度的低硫轻质油,之前从这里开采的348桶原油已被炼制。爱尔兰油气分析师Brendan D’Souza表示,这个让人震惊的产量远远超过预期。
根据斯伦贝谢的研究,Horse Hill油藏是英国陆地石油最重要的供应来源之一。今年八月,经油服公司计算,在这不足55平方英里的范围内就有109.93亿桶原油储量。斯伦贝谢公司最新的估计建立在对Horse Hill-1井岩石物性评价的基础上,此井位于PEDL137靠近伦敦的盖特威克机场。根据美国岩石物性分析公司先前的一份报告估计,Horse Hill-1井所在的区域就有1.58亿桶原油/平方英里的储量。
在欧洲其他地方,俄罗斯石油公司的子公司RN-Uvatneftegaz在1月份宣布,在Zapadno-Epasskoye油田发现商业油流,这是俄罗斯秋明地区Uvat项目的一部分。俄罗斯石油公司声明,这个油田的石油探明储量超过1.21亿桶。同时,在Nervesa气田也发现了商业气流,它位于意大利东北岸,目前计划将产量增加到180万立方英尺/天。(商业油流,是广泛用于评价某一油井/油层产量具有商业价值的最低极限值)石油圈原创,石油圈公众号:oilsns
中东和非洲
在中东,伊朗的North Azadegan 和Yadavaran油田开发项目正在启动。继位于Karoun河西部两个油田扩建之后,现在伊朗的产量有潜力提高到约16万桶/天。一月份制裁解除后,伊朗的增产计划如期实现。石油圈原创,石油圈公众号:oilsns
当国有石油巨头沙特阿美公司透露他们已开始经营与Wasit项目相关的增产项目时,沙特阿拉伯在今年年初也有了明显增产。沙特阿拉伯Wasit海上天然气田预计在不久的将来开始获得商业气流。另外一个中东油气田开发项目启动也在二月公布,以Najiyah油田的名义,澳大利亚Petsec能源公司获得了100%的参与权。在2014年该油田停产之前,Najiyah油田已生产原油2500万桶,该油田从2004年开始投产,共有25口井,在2006年3月已达到12716桶/天的产油峰值。
自2016年初以来,非洲也开始了几个油田开发的项目,海上Angola Mpungi油田和阿尔及利亚南部油田项目相继在一月和二月开展。作为West Hub Development Project(WHDP)的一部分,埃尼公司1月11日宣布Angola Mpungi油田海上项目正在实施,这标志着WHDP油田三期项目的启动。该油田有望在第一季度发展将原油产油提高到约10万桶/天。
阿尔及利亚国家石油公司、英国石油公司和挪威国家石油公司合资在2月份开始了在阿尔及利亚南部的油田项目,包括Gour Mahmoud、In Salah、Garet el Befinat和Hassi Moumene干气田的扩建项目。Hassi Moumene 和 Garet el Befinat油田计划将天然气产量增加到500万立方英尺/天。石油圈原创,石油圈公众号:oilsns
非洲其他增产计划还包括位于尼日利亚海上的Aje油田和在坦桑尼亚的Kiliwani North-1井。根据Panoro能源的统计,Aje油田原来的两口井估计可生产2850万桶石油。另外计划中的两口井有望带来超过5000万桶的产量。Kiliwani North 1井预计产量达30万桶/天,相当于超过5000桶的石油当量。
亚洲
中海油在2月份宣布,开始涠洲12-2油田联合开发项目和涠洲11-4北油田二期项目,这两个油田开发项目都位于中国南海的北部湾盆地。涠洲12-2项目的油田位于约118英尺水深的海域,包括涠洲12-2、12-1西部和涠洲11-2的北部的三个油田。中海油表示,该项目的主要生产设施包括3个井口平台和18口生产井,目前日产大约1.6万桶原油。
位于平均水深131英尺的涠洲11-4北部地区,目前生产设施有2个井口平台和15口生产井。中海油表示,目前只有一个井在作业,日产大约500桶原油,预计日产大约8000桶原油的最高产量预计在年内达到。中海油也在今年早些时候投产了渤海南部的垦利10-4油田。目前在垦利10-4油田共有6口井在生产,每天生产总计约6540桶的原油。该油田预计在2016年将达到大约9600桶原油的最高产量。石油圈原创,石油圈公众号:oilsns
另外,中国石油天然气集团公司和雪佛龙公司将中国西南川东北酸气项目提上议程。川东北项目占地面积超过309平方英里,主要包括罗家寨、铁山坡、渡口河-七里北等几个气田。其中,罗家寨气田预计天然气产量高达1095.3亿立方英尺/年,目前日产气为34.6千万立方英尺。

Oil and gas production projects get underway in Europe, Asia, the Middle East and Africa. Production start-ups have occurred all over the globe within the first few months of this year, with considerable increases in Europe, the Middle East and Africa. Several additional projects across the latter two regions are expected in the near future, and a variety of recent developments in East Asia are expected to ramp-up their outputs by year-end.
In Europe, Total’s UK-operated Laggan-Tormore development in the West of Shetland area, will produce 90,000 barrels of oil equivalent per day (boepd). Despite its status as a “key component” of Total’s future production growth, the Laggan-Tormore project has been delayed numerous times, with output commencement initially expected at the end of 2014. Situated in 1,968 feet of water, the Laggan-Tormore gas and condensate fields feature an 86-mile tie-back of four subsea wells to an onshore Shetland gas plant, which has a capacity of 500 million cubic feet of gas per day (MMcf/d).
Deirdre Michie, the chief executive for Oil & Gas UK, emphasized the benefits the field has brought to the UK hydrocarbon sector in an organization statement in February.“The confirmation of first gas production from the Laggan-Tormore field is very welcome news at a challenging time for the UK oil and gas industry as a whole,” she said. “Developing the field attracted billions of pounds of investment to the UK, employed thousands of people and required technological innovation over many years. Production from the field will supply a significant proportion of the UK’s gas needs, supporting energy security at a time of sustained dependence on gas as a fuel.”
Another European production start-up got underway in February at the Horse Hill-1 discovery in the UK’s Weald Basin. Oil flowed from the well at an initial rate in excess of 700 barrels of oil per day (bopd), in an approximate mix of 50:50 oil to water, before stabilizing to more than 463 bopd, in an approximate mix of over 99 percent oil and less than 1 percent water. Light, 40-degree API, sweet oil continued to flow naturally to surface at the Horse Hill-1 at a steady rate in excess of 456 bopd, and the first two tankers full with 348 barrels of oil from the site have already been sent to be refined. Brendan D’Souza, an oil and gas analyst at WH Ireland, said the results have been highly impressive and far exceed expectations.
The Horse Hill discovery could lead to one of the most significant oil supplies found onshore UK, according to Schlumberger’s research. In August, the oilfield services firm calculated that 10.993 billion barrels of mean oil in place was imbedded within the 55 square miles of the PEDL137 and PEDL246 Horse Hill licenses. Schlumberger’s latest estimates build on the company’s previous petrophysical evaluation of the Horse Hill-1 well, located in PEDL137 near to London’s Gatwick Airport. A previous report by U.S. petrophysical analysis firm Nutech estimated that the Horse Hill-1 well contained a total OIP value of 158 million barrels per square mile.
Elsewhere in Europe, RN-Uvatneftegaz, a Rosneft subsidiary, announced in January that commercial oil production had started at the Zapadno-Epasskoye field, which is part of the Uvat project in Russia’s Tyumen Region. Recoverable oil reserves at the field amount to over 121 million barrels, according to a Rosneft statement. First commercial production also occurred at the Sound Energy operated Nervesa gas discovery, located onshore northeast Italy, which is currently ramping up to a planned output rate of 1.8 MMcf/d.
The Middle East And Africa
In the Middle East, two production start-ups stemmed from Iran’s North Azadegan and Yadavaran development projects. Following the completion of expansion work at the two oilfields, which are located west of the Karoun River, North Azadegan and Yadavaran, now have the potential to boost Iran’s production capacity by around 160,000 bopd. The latest development in the country follows Iran’s plans to boost output after sanctions were lifted in January.
Saudi Arabia also saw a significant production development at the start of the year, when state oil giant Saudi Aramco revealed it had started to operate one of the output processing units associated with the Wasit project. Offshore gas production from the Saudi Arabian Wasit venture is expected to begin in the near future. An additional Middle Eastern production start-up was announced in February, in the form of the An Nagyah oil field, after Australia’s Petsec Energy Ltd acquired a 100 percent participating interest in. Prior to its suspension in 2014, the An Nagyah oil field had produced 25 million barrels of oil since 2004 from 25 wells, reaching a peak oil rate of 12,716 bopd in March 2006.
Several output commencements have occurred in Africa since the start of 2016, too, with the offshore Angola Mpungi field and the Southern Fields project in Algeria coming online in January and February, respectively. Eni announced Jan. 11 it had brought the offshore Angola Mpungi field on-stream as part of the latest phase of the West Hub Development Project, marking the third WHDP field start-up. This field is expected to ramp-up production from the development to approximately 100,000 bopd within the first quarter.
The Sonatrach, BP and Statoil joint venture, In Salah Gas, said in February it would begin production of the Southern Fields project in Algeria, which comprises the development of the Gour Mahmoud, In Salah, Garet el Befinat and Hassi Moumene dry gas fields. Production from the SF project is planned to ramp up to 500 MMcf/d as wells in the Hassi Moumene and Garet el Befinat fields are brought online.
Other African assets scheduled to begin production include the Aje field, located offshore Nigeria, and the Kiliwani North-1 well, in Tanzania. Aje will produce an estimated 28.5 million barrels of oil from two initial wells, according to Panoro Energy. Two further wells are expected to bring total Cenomanian oil production from the field up to over 50 million barrels. The Kiliwani North 1 well is anticipated to produce at an approximate rate of 30 MMcf/d, equivalent to more than 5,000 bopd, according to Solo Oil.
Asia Production
China’s CNOOC Limited announced in February it has started production at the Weizhou 12-2 oilfield joint development project and the Weizhou 11-4 North oilfield Phase II project, both in the Beibu Gulf Basin of the South China Sea. The Weizhou 12-2 project, which lies in an average water depth of approximately 118 feet, has three oilfields comprising Weizhou 12-2, Weizhou 12-1 West and the north part of Weizhou 11-2. CNOOC indicated that the project’s main output facilities include three wellhead platforms and 18 production wells, currently producing a total of 16,000 bopd.
Weizhou 11-4 North, in average water depths of 131 feet, makes use of two wellhead platforms and 15 producing wells. The state-owned Chinese firm has said only one well is currently in operation, producing around 500 bopd, although peak production of approximately 8,000 bopd is expected from the project this year. CNOOC also brought the Kenli 10-4 oilfield in the South of Bohai online earlier this year. There are currently six producing wells at Kenli 10-4 with an output total of approximately 6,540 bopd. The oilfield is expected to reach peak production of approximately 9,600 bopd in 2016.
In southwest China, China National Petroleum Corp. and Chevron Corp. brought the Chuandongbei Sour Gas Project online. The Chuandongbei project occupies an area of over 309 square miles and consists of several gas fields including Luojiazhai, Tieshanpo, and Dukouhe-Qilibei. The Luojiazhai gas field, which is designed to produce 109.53 billion cubic feet per annum, currently produces 346 MMcf/d.
