Dylan Marshall Crain
Ph.D. Student in Energy Resources Engineering, admitted Autumn 2022
Current Research and Scholarly InterestsMy current research revolves around optimizing the monitoring design of Carbon Capture and Sequestration (CCS) projects in such a way that the posterior (after data assimilation) predictions are as close to reality as can be hoped for.
In CCS projects within the U.S., it is important to have monitoring plan, which can consist of wells with pressure, saturation, salinity, et cetera sensors, seismic lines, or gravimetric above-ground measurements, before any injection has begun into the subsurface. This is due to the permitting requirements that must be satisfied before operations are begun.
Due to this constraint, any monitoring optimization (at least initially) needs to be determined using only a prior (highly uncertain) understanding of the subsurface. This makes the optimization much more challenging. We utilize a prior optimization scheme from a previous student which allows us to optimize a monitoring plan using only prior information to get the minimized, expected uncertainty reduction in the posterior models for a given quantity of interest. This scheme is limited by some Gaussian assumptions. We optimize it using a genetic algorithm.
From this point, with the monitoring plan established, the information gathered from the optimized monitoring scheme (using only monitoring wells at the moment) is used to history match (data assimilate) our understanding of the subsurface. The results can be used to predict the CO2 plume flow and behavior into the future.
This work was initially developed to assist a project in Illinois that is currently seeking Class VI injection well permits in the self-same state in order to begin injecting CO2 produced from two companies paying for the work from the Illinois Geological Survey. -

Emma Shaw Crane
Assistant Professor of Anthropology
BioEmma Shaw Crane is an urban and environmental anthropologist. Her research and teaching focus on war, environment, and racialization in the urban Americas.
Her current book project, Counterinsurgent Suburb, is a study of the environmental and spatial arrangements that sustain U.S. empire on the peripheries of Miami, Florida. It draws on ethnographic fieldwork across a military base, a detention camp for migrant children, a nuclear power plant, and industrial plantations sustained by Indigenous Maya migrant workers. The project engages war as a transnational racial project that is routinized and reproduced in the American suburb.
A second project examines aftermaths of war in Bogotá and draws on long-term fieldwork with former guerrilla combatants in Colombia’s civil war. It examines how peripheral neighborhoods become the targets of municipal, humanitarian, and insurgent efforts to repair past atrocity, often in ways that seek to remake urban built environments.
Crane’s work is grounded in the principles and practices of research justice. She currently co-directs a project investigating a county jail and federal migrant detention center in Glades County, Florida.
