“…Similar field observations were recently reported at the sites of cold, liquid or supercritical, CO 2 injection for geological carbon storage (Rangriz Shokri et al., 2019; Zhou et al., 2020). The maximum temperature reduction varied from 30°C at Ordos, China to 60°C at Cranfield, Mississippi, USA.…”

Injection of cold fluids through/into deep formations may cause significant cooling, thermal stress, and possible thermal fracturing. In this study, the thermal fracturing of low‐permeability formations under one‐dimensional heat conduction was investigated using a plane strain model. Dimensionless governing equations, with dimensionless fracture length scriptL $\mathcal{L}$, aperture normalΩ ${\Omega}$, spacing scriptD $\mathcal{D}$, time τ $\tau $, and effective confining stress scriptT $\mathcal{T}$, were derived. Solution of single thermal fracture was derived analytically, while solution of multiple fractures with constant (or dynamic) spacing were obtained using the displacement discontinuity method (and stability analysis). For single fracture, scriptL(τ,T) $\mathcal{L}(\tau ,\mathcal{T})$ increases nonlinearly with τ $\sqrt{\tau }$ and then transitions to scaling law scriptL=f(scriptT)τ $\mathcal{L}=f(\mathcal{T})\sqrt{\tau }$, indicating that late‐time fracture length increases linearly with the square root of cooling time. For constantly spaced fractures, scriptL(τ,T,D) $\mathcal{L}(\tau ,\mathcal{T},\mathcal{D})$ deviates from the single‐fracture solution at a later τ $\tau $ for a larger scriptD $\mathcal{D}$, showing slower propagation under inter‐fracture stress interaction. For dynamically spaced fractures, fracture arrest induced by stress interaction was determined by the stability analysis; the fully transient solution provides evolution of dimensionless fracture length, spacing, aperture, and pattern; a similar scaling law, scriptL=f′(scriptT)τ $\mathcal{L}={f}^{\prime }(\mathcal{T})\sqrt{\tau }$ with f′(T)

“…At Cranfield, three subsequent tracer tests were conducted using SF 6 and Kr (Lu et al, 2012; Zhou et al, 2020). The first tracer was injected 2 days after the initiation of CO 2 injection, and the subsequent tracer tests were conducted after 4 and 5 months later.…”

Tracers are used to tag the injected carbon dioxide (CO 2) for verification of the storage performance and containment in geosequestration. Yet the characterization of the transport behavior of a chemical tracer in two-phase flow system has not been fully investigated. We present experimental observations together with numerical results for both homogeneous and heterogeneous media from core scale to field scale. The key features of the breakthrough curves (BTCs) that include the tracer arrival time, peak concentration, and tailing pattern were examined. We identify distinct differences in BTCs depending on whether the formation was previously swept by CO 2. When the tracer is released before CO 2 sweeps the formation, the tracer transports at the front of gas-liquid interfaces with a narrow tracer plume distribution and the BTCs reflect the effect of local heterogeneity. Furthermore, a series of tracer pulse can be used to identify whether new pathways have been developed during CO 2 injection. Plain Language Summary Geologic storage of carbon dioxide (CO 2) has become an attractive climate change mitigation option, and ensuring the containment of injected CO 2 is of prime importance for successful geological storage. Tracers are an effective means of tracking injected CO 2 and verifying containment within the storage formation. Here we show that distinctive features in observed tracer data are highly related to whether or not the storage formation was previously swept by CO 2. When the tracer is released at the beginning of CO 2 injection, the tracer moves with narrow distribution and is advantageous for the tracer data to reflect multiple pathways. By contrast, once the CO 2 sweeps the formation, the tracer moves much faster with a wider dispersion pattern.

Quantitative characterization of subsurface properties is critical for many environmental applications and serves as the basis to simulate and better understand dynamic subsurface processes. Geophysical imaging methods allow to image subsurface property distributions and monitor their spatio-temporal changes in a minimally-invasive manner. While it is widely agreed upon that models integrating multiple independent data sources are more reliable, the number of approaches to do so is increasing rapidly and often overwhelming for researchers and, particularly, novices to the field.With this work, we aim to contribute to the development multi-method imaging through (1) an overview of, and didactic introduction to, existing inversion approaches for the integration of multiple geophysical data sets with other measurement types (e.g., hydrological observations), petrophysical models, and process simulations, (2) a state-of-the-art review on the use and potentials of these approaches in various environmental applications, and (3) a discussion on new frontiers and remaining challenges in the field.We hope that this chapter provides an entry point to recent developments in multimethod geophysical imaging, clarifies similarities, differences and development potentials of existing approaches, and ultimately helps practitioners to choose the optimum one to integrate their data sets.
