I have been working in the petroleum industry for more than 35 years now. As I reviewed papers for this feature, I reminisced about a couple of events in my early career. First, as I was looking through petroleum journals, an article on the pending oil shortage caught my interest. The author outlined how, at current or increasing production rates, current development scenarios, and current prospective of new discoveries, oil production would soon peak. Thus, with increasing oil demand, a world oil shortage was imminent. The author did not believe there were any significant unexplored oil-bearing regions that could arrest the upcoming demise. This article was written in the early 1920s. This was not the last such article in the last 100 years. The combination of technology advances and world politics results in oil supply-and-demand cycles that have occurred repeatedly over the past 100 years and that have affected and will continue to affect our careers.
Second, about the same time 30 years ago, I was taught a timely lesson. As we were forging ahead in carbon dioxide (CO2)/oil/brine phase-behavior research at reservoir conditions, I was explaining some of our advances to a company colleague. He had been with the company for about 20 years, and I was delighted that he seemed so interested as he listened and asked pertinent questions. He then related how he had worked in an earlier enhanced-oil-recovery group that had been disbanded because of low oil prices. The irony of this was that I had not known of the existing corporate knowledge in my area of research. If I had, it would have saved some time, advancing our work.
These events both show the importance of documenting work and reviewing the literature. Not only knowledge of recent advances, but a historical perspective is important for significant advances in the industry. I commend SPE for its many conferences and other forums for technology transfer and for the conference policy of “no paper, no podium.” This is not the case in many scientific and engineering societies. This policy provides volumes of information that would otherwise not be publicly documented and also a multitude of manuscripts from which papers for peer review can be selected.
Papers related to CO2 applications in the literature this year covered a variety of topics from nanolevel investigations to full-scale field development, representing the international extent of SPE and including subjects such as reservoir fracturing, enhanced oil recovery, and carbon storage. The following pages summarize four articles that highlight activities related to CO2 applications. These articles represent the variety, advances, and constants that continue in the use of CO2 to improve petroleum-industry results.

CO2 injection is a successful EOR technology that has been deployed extensively in the Permian Basin. Further expansion of CO2 EOR has been limited by the availability of affordable CO2 rather than the existence of suitable target reservoirs. This situation may be about to change.
The evolution of horizontal drilling and multistage completions has changed matrix stimulation from the “more acid, better result” belief to effective lateral distribution and deeper penetration with less acid.

While the floating liquefied-natural-gas (FLNG) option initially looked promising, high capital expenditure and very high operational expense (OPEX) have limited its potential application, with four potential FLNG projects being canceled in Australasia in the last 2 years.
