IOG油气公司在英国北海Skipper油田钻取了第一口评价井，但探井结果喜忧参半。IOG称：该评价井从Skipper油田中提取并检测油样以优化开发方案。虽然检测证明石油资源确实存在，但结果显示油样密度约为11° API，且黏度大大高于预期。
重油一般具有高黏度和高密度。美国石油学会规定密度低于22.3°API的原油即为重油， 其氢碳比重较低，含有大量沥青烯、硫、氮和重金属成分，且含酸量较高，开采难度较大。这意味着IOG需要在未来数月开展进一步的油样测试，并审核Skipper项目开发方案。

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.
