Texas A&M University researchers demonstrated that unsupervised machine learning algorithms could analyze data from a geological carbon sequestration site to determine and model underground carbon dioxide (CO2) plume locations and movements.

The algorithms evaluate CO2 presence in the data using five broad or qualitative ranges, identified by color for a two-dimensional visual representation; their results accelerated the pinpointing of plume location, coverage area, and its approximate size, shape, and density.

Texas A&M's Siddarth Misra said, "We are letting the data tell us where the CO2 actually is. We are also providing rapid visualization because if you cannot see the CO2, you cannot control it deep underground."
