最近有人提醒我，术语 IOR（提高石油采收率）和 EOR（提高石油采收率）并不总是被我们行业中的每个人使用相同的方式。

当我在 20 世纪 90 年代末和 2000 年代初担任 SPE EOR/IOR TIG（技术兴趣小组）的前联合主席时，我们对这些术语的使用方式进行了一次非正式的简短调查。下图显示了当时该术语最常见的三种用法：选项 1、2 和 3。

早期调查结果显示，该技术的大多数主题专家（约 50% 至 60%）更倾向于使用选项 1，但也有一些人使用选项 2（约±30%），少数人使用选项 3（±10%） ）。这种差异来自接受调查的不同群体。

斯坦福大学的 Henry (Hank) Ramey 博士和 William (Bill) Brigham 博士教了我选项 1，所以这是我的偏好。但是，由于我认为我们的行业应该在沟通中尽可能清晰，因此我想再次对我们的社区进行非正式民意调查。

该调查链接已发布在SPE Con​​nect 技术社区、油藏和生产以及SPE 研究和开发技术部分的讨论中。

请通过完成一项简单的三问题调查来分享您的意见。它将一直开放到 2023 年 10 月 15 日。

我将尽力在 10 月底之前收集并总结反馈意见，或者如果可能的话，在圣安东尼奥 SPE 年度技术会议和展览之前收集和总结反馈意见。

I was recently reminded that the terms IOR (improved oil recovery) and EOR (enhanced oil recovery) are not always used the same by everyone in our industry.

While I served as a past co-chair of the SPE EOR/IOR TIG (Technical Interest Group) in the late 1990s and early 2000s, we did an unofficial, brief survey on how these terms were used. The figure below shows the three most common uses of the terms at that time, Options 1, 2, and 3.

The results of the earlier survey showed that most subject matter experts in this technology (about 50 to 60%) preferred to use Option 1, but some used Option 2 (approximately ±30%), and a few used Option 3 (±10%). The variation came from different groups that were polled.

Henry (Hank) Ramey, PhD, and William (Bill) Brigham, PhD, both of Stanford University, taught me Option 1, so that is my preference. However, since I believe that our industry should try to be as clear as possible in our communication, I would like to informally poll our community again.

The survey link has been posted in discussions in the SPE Connect technical communities, Reservoir and Production, and on the SPE Research and Development Technical Section.

Please share your opinion by completing a simple, three-question survey. It will remain open until 15 October 2023.

I will do my best to collect and summarize the responses toward the end of October or, if possible, before the SPE Annual Technical Conference and Exhibition in San Antonio.
