据美国油价网2022年1月25日报道，高影响力的石油和天然气钻井活动在2020年经历了10年低点以后，在去年恢复了增长加。2020年疫情和需求暴跌导致石油和天然气公司削减钻井预算并推迟钻井活动。  

全球著名商业咨询服务多元化供应商IHS Markit日前在一份关于高影响力井的最新报告中称，去年全球共完成了1500多口勘探井和评价井，比前一年有所增加，产出至少138亿桶油当量的碳氢化合物。  

IHS Markit全球信息技术研究总监Jack Rivers写道：“尽管面临着行业挑战，但从资源的远景来看，去年仍然可以实现。”

IHS Markit表示：“考虑到持续疫情的逆风和能源转型给上游带来的挑战，去年全球钻井数量略有增加，这才是重要的。” 

根据IHS Markit的数据，其中约有30个发现的油气储量超过1亿桶油当量，共交付了总探明油气储量的82%。

IHS Markit表示，去年全球在排名前30位的新发现中，有许多发现来源于高影响力井，去年总体上是高影响力井钻井的成功。

去年全球开钻了32口高影响力井，其中约三分之二的高影响力井获得了发现。 IHS Markit表示，其中一些发现规模很大，去年新发现的绿地资源中，高影响力井占了近一半。

在高影响力井方面，去年拉丁美洲以完钻17口高影响力井居榜首，其中巴西8口，墨西哥5口，其余在圭亚那、苏里南、秘鲁和玻利维亚。  

今年，全球计划开钻20多口高影响力井，其中6口在去年底或今年初开钻的高影响力井将在今年年内完钻。 此外，还有15口高影响力井也可能在今年开钻。 根据IHS Markit的数据，这些钻井项目被归为“暂定”项目，因为它们计划中的钻井状况仍存在不确定性。

“单单去年的发现就证明高影响力井仍然是勘探的一个基本层面。 今年高影响力钻井将继续对全球勘探产生影响，未来一年将有一些有吸引力的钻井计划。”IHS Markit如是表示。

High-Impact Oil And Gas Drilling Makes A Comeback

High-impact well drilling activity returned to growth in 2021 after a decade-low in 2020 when the pandemic and crash in demand made oil and gas companies slash drilling budgets and defer campaigns.

More than 1,500 exploration and appraisal wells were completed last year, up from the previous year, and delivering at least 13.8 billion barrels of oil equivalent (boe), IHS Markit said in a new report on high impact wells.  

“Even with the industry challenges, 2021 still delivered from a resource perspective,” Jack Rivers, Director - Technical Research, Global Content, IHS Markit, wrote.

“2021 provided a slight uptick in drilling which is significant considering the headwinds of the continuing pandemic and the challenges to upstream provided by the energy transition,” IHS Markit said.

Around 30 of the discoveries had more than 100 million boe, and delivered 82 percent of total discovered volumes, according to the consultancy. 

Many of the top 30 discoveries were drilled with high-impact wells, and 2021 overall was a success for high-impact well drilling, IHS Markit said.

As many as 32 high-impact wells were spudded last year, and some two-thirds of those made discoveries. A number of these discoveries were large, and HIWs in total contributed to nearly half of the newly discovered greenfield resources in 2021, IHS Markit said.

Latin America led in terms of high-impact wells with 17 in total, with eight in Brazil, five in Mexico, and the rest drilled in Guyana, Suriname, Peru, and Bolivia.

This year, more than 20 high-impact wells are planned, while six wells which spudded in late 2021/early 2022 are due to complete in 2022. In addition, there are another 15 high-impact wells that could also spud in 2022. Those are classed as ‘tentative’ where uncertainty remains over their planned drilling status, according to IHS Markit’s data. 

“HIWs remain a fundamental aspect of exploration as proven by 2021 discoveries alone. HIW drilling for 2022 will continue to have a global bearing on exploration and there a re some interesting wells planned for the forthcoming year,” said IHS Markit.
