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. -
Craig Criddle
Professor of Civil and Environmental Engineering, Emeritus
Current Research and Scholarly InterestsCriddle's interests include microbial biotechnology for the circular economy, including recovery of clean water from used water, renewable energy, valuable materials that can replace fossil-carbon derived materials. Current projects include energy-efficient anaerobic wastewater treatment technology, assessment of new treatment trains that yield high quality water; fossil carbon plastics biodegradation, and biotechnology for production of bioplastics that can replace fossil carbon plastics.

Sadie Rosalie Gruenwald Cwikiel
Casual - Non-Exempt, Center for Ocean Solutions
BioSadie is a senior majoring in Earth Systems in the Oceans and Climate track and minoring in creative writing. She grew up in Northern Michigan and has always loved spending time outside. She is interested in oceanography, tropical ecosystems, and conservation. Her favorite Stanford quarter was spent studying ecology and anthropology during the Wrigley Field Program in Hawaii. Her group research project on parrotfish in Hawaiian coral reefs inspired her love for marine ecosystems. Sadie also studied abroad in Santiago, Chile, and enjoyed hiking in the Andes and practicing Spanish. She has spent her summers researching the impacts of drought and flooding events on soil respiration, working with a citizen science program in the Peruvian rainforest, and sailing through the Phoenix Islands Protected Area during a SEA Semester. Outside of academics, Sadie enjoys leading SPOT and adventure trips with Stanford Outdoor Education, leading tours at Jasper Ridge, playing drums in LSJUMB, creative writing, and dancing. In her free time, she likes to go hiking and camping, do ceramics, or go to the beach.
