  • Because the basics of CCS and CCUS are mostly familiar to a large part of the readership, I am choosing to bring to your attention the summary of those articles that are devoted to approaches other than or beyond CCS, even if they have to climb further on the development ladder. These include bio-based approaches, geothermal, and use of hydrogen as a substitute fuel.
  • Statistics are important in knowing where the sharp minds of SPE members are investing their energies. Typically, this is also in proportion to what those members need. Hence, it is noteworthy that more than a fifth of the papers were about CO2-based EOR, indicating not only renewed interest but also the motivation for carbon capture, use, and storage.
  • The enhanced-oil-recovery literature produced in the past several months was dominated by reservoir modeling and characterization; flood enhancements; machine learning; and, more notably, relative permeability estimation. This last one needs to be understood further.
  • The bulk of the literature on enhanced oil recovery from the past year has been devoted to an improved understanding of trends started more than a decade ago with physical and numerical modeling.
