Fifty three years ago, on this day, January 26th, 1972, a new technology came along.
CO2-enhanced oil recovery (EOR) has been carried out in the United States and Canada since the 1960s. The world’s first large-scale CO2-EOR project, Scurry Area Canyon Reef Operating Committee (SACROC), has been implemented by Chevron in the oilfield in Scurry County, Texas since January 26, 1972 [13]. The CO2 for this project comes from the natural CO2 fields in Colorado and is pipelined to the oilfield for flooding. More than 175 million tonnes of natural CO2 in total were injected in the SACROC project during 1972–2009 [14].
The amount of carbon dioxide in the air was roughly 327ppm. As of 2025 it is 425ppm, but check here for daily measures.
The context was that economies were still growing at a rate that we would now consider either astonishing or Chinese. Energy companies were looking to extract more oil and gas, of course, and to do it as cheaply as possible. In retrospect, we can now see this is the formal beginning of enhanced oil recovery. But at the time, I guess it was just one more experiment (EOR had already been piloted on a much smaller scale).
What I think we can learn from this is that EOR, which is still the raison d’etre behind CCS, or the only way that it will make money, has a long history, longer than 1972.
What happened next
Well, CCS had a long, slow development process. There were studies in the late 70s through the 80s. There was momentary interest in it in 1989 and then the people who would have done it realized how much it would cost and how they could get more bang for their buck elsewhere. And CCS finally took off in the 2000s because the Kyoto Protocol looked like it might come into force, and rich nations needed something with which to pretend to be taking action.
Somebody should write a book. Oh, wait.
What do you think? Does this pass the ‘so what?’ threshold? Have I got facts wrong? Interpretation wrong? Please do comment on this post, unless you are a denialist, obvs.
