Task 3 - Improve quantitative models of CO2 plume activity in reservoirs using perfluorocarbon and geochemical tracer data in new simulator modules.

Maximizing the value of tracer data requires modeling with a reservoir simulator to quantify the degree of CO2 dispersion, dissolution, fingering, and other transport properties of the CO2 plume. Estimating these parameters using unprecedented PFT and isotope measurements is addressing the main metrics of CO2 plume area and pressure differentials that control leakage and induced seismicity risk. Predicting these properties through a new tracer-simulation MVA package that leverages capabilities of an advanced reservoir simulator is the goal of this task.
