Research:
Dr. Heidari’s research team develops new methods for reliable interpretation and integration of multi-scale (i.e., pore-scale, core-scale and well-log-scale) formation data measured in the laboratory or in the subsurface in challenging formations such as organic-rich mudrocks and carbonate formations. These new unconventional methods include (a) laboratory measurement techniques and (b) interpretation techniques to characterize unconventional rocks, where conventional methods often fail. Her team’s research outcomes improve evaluation of static and dynamic formation properties, which leads to enhanced reservoir characterization and production planning in both conventional and unconventional reservoirs.
