Modeling of CO2-driven cold-water geyser in the northeast Qinghai-Tibet plateau

Investigating the Changes in Periodicity of the CO2‐Driven Cold‐Water Geyser Eruptions Through Field Observation at Tenmile Geyser, Utah

“…Through the analyses of naturally driven geyser eruptions, essential factors, including C CO 2 , P , T , and v , were identified (Cai et al., 2021; Lu et al., 2006). Pressure can be artificially controlled through pumping to induce CO 2 eruption.…”

“…The exsolution of non‐condensable CO 2 gas from CO 2 ‐rich water can lift deep formation water to a wellhead (Han et al., 2013; Ladd & Ryan, 2016). The eruption duration (ED) of a CO 2 geyser is divided into self‐enhancing and self‐limiting processes, which are governed by in‐well controlling factors such as pressure, CO 2 concentration, depth of CO 2 bubble generation (flashing depth (FD)), and recharge rate from the sourcing aquifer (Cai et al., 2021). If the geological and hydraulic conditions are constant, the ED and strength of eruption will remain unchanged.…”

A multiphysical‐geochemical coupling model for caprock sealing efficiency in CO2 geosequestration

“…As an effective mitigation strategy for the reduction of CO 2 concentration in the atmosphere, CO 2 geosequestration has received more and more attention (Bachu & Bennion, 2008; Beerling et al, 2020; Huisingh et al, 2015; Isah et al, 2022; Lehmann & Possinger, 2020; Xie et al, 2022). CO 2 injected into the deep ground layer generally migrates in two stages: the first stage is the CO 2 transport within the storage reservoir; the second stage is the CO 2 accumulation beneath caprock (Cai et al, 2021; Heath et al, 2012; Hou et al, 2012; Shang et al, 2022). More and more studies have shown that CO 2 possibly migrates to shallow aquifers and pollutes freshwater resources (Carroll et al, 2014; Keating et al, 2013; Ruggieri & Gherardi, 2020; Smith et al, 2013; Takaya et al, 2017; Wang & Wang, 2018).…”
