IOG油氣公司在英國北海Skipper油田鉆取了第一口評價井,但探井結果喜憂參半。IOG稱:該評價井從Skipper油田中提取并檢測油樣以優化開發方案。雖然檢測證明石油資源確實存在,但結果顯示油樣密度約為11° API,且黏度大大高于預期。
重油一般具有高黏度和高密度。美國石油學會規定密度低于22.3°API的原油即為重油, 其氫碳比重較低,含有大量瀝青烯、硫、氮和重金屬成分,且含酸量較高,開采難度較大。這意味著IOG需要在未來數月開展進一步的油樣測試,并審核Skipper項目開發方案。

Independent Oil & Gas (IOG), a company working to develop its Skipper oil discovery in the UK sector of the North Sea, has shared mixed results of its first operated appraisal well there. The appraisal well was completed and, IOG says, it achieved its primary objective of retrieving oil samples from the Skipper reservoir in order to optimize the Skipper field development plan. However, while the drilling of the appraisal well proved oil, the first sample results indicate that the oil is approximately 11° API and has a significantly higher viscosity than expected, IOG said.
Crude oil with high viscosity (typically above 10 cp), and high specific gravity is considered heavy. The API classifies heavy oil as crudes with a gravity below 22.3° API. Heavy oils typically have low hydrogen-to-carbon ratios, high asphaltene, sulfur, nitrogen, and heavy-metal content, as well as higher acid numbers, and might be difficult to extract. This means IOG now needs to do more testing of samples and review its Skipper development options, which could take months to complete.
