“…In this case, the value 0.4 is selected as the threshold based on visual inspection of the results. The lack of sensitivity of the time‐lapse seismic response to fluid changes is also observed in other studies (Gasperikova et al., 2022; Schmitt et al., 2022). Figure 9 shows the inverted porosity and CO 2 saturations obtained using seismic data alone.…”

“…Time‐lapse (4‐D) seismic acquisition is one of the monitoring techniques widely deployed in GCS projects, where a series of seismic surveys are sequentially acquired to quantify changes in reservoir properties (e.g., elastic properties, fluid pressure and saturation) during and after CO 2 injection (Caspari et al., 2011; A. Chadwick et al., 2010; Egorov et al., 2017; Glubokovskikh et al., 2020; Grude et al., 2013; B. Li & Li, 2021; Rubino et al., 2011). However, in some cases, depending on the rock stiffness, the time‐lapse seismic response might be insensitive to fluid changes (Gasperikova et al., 2022; Schmitt et al., 2022). To address this issue, non‐seismic monitoring techniques have been investigated and successfully applied to GCS.…”

Geologic CO 2 sequestration (GCS) is one of the main mitigation strategies to prevent carbon dioxide (CO 2 ) from entering the atmosphere by capturing and injecting it into subsurface geological formations, such as depleted oil reservoirs and deep saline aquifers (Aminu et al., 2017;Metz et al., 2005). To ensure safe and long-term CO 2 storage, geophysical monitoring surveys are periodically acquired to surveil the behavior of the injected CO 2 and make informed decisions for storage management (Davis et al., 2019). Time-lapse (4-D) seismic acquisition is one of the monitoring techniques widely deployed in GCS projects, where a series of seismic surveys are sequentially acquired to quantify changes in reservoir properties (e.g., elastic properties, fluid pressure and saturation) during and after CO 2 injection (Caspari et al.

“…The spring stiffness k can be expressed as: (1) where E is Young's modulus of silicon (130 GPa [29], [30]), b and h are width (17 μm) and length (500 μm) of the spring section respectively, and L is the length of spring beam (7 mm). Taking the derivative of (1) with respect to temperature and dividing both sides by k, we have (2) It can be seen that the temperature coefficient of the spring stiffness comprises the contribution of the Young's modulus (-80 ppm/K [29] to -60 ppm/K [30]) and the thermal expansion coefficient of silicon (2.6 ppm/K [31]). Considering that the fixture for installation and other parts that may introduce additional temperature effects, the overall temperature coefficient of the assembled MEMS gravity sensor was measured to be 87.3±3.3 μGal/mK in our case.…”

Precision measurements of local gravitational acceleration variations are of great importance in geophysical surveys. With advantages such as cost-effectiveness and portability, Micro-Electro-Mechanical system (MEMS)-based gravimeters have shown the potential for long-term gravity measurements. In this paper, aiming to further improve the stability of the instrument, the design considerations and system evaluations of a MEMS gravimeter are presented. With a linear spring design for the silicon proof-mass, a low natural frequency of ~14 Hz and a large linear range of ~10300 mGal are achieved with an ultra-low self-noise floor of 1.2 μGal/√Hz@1 Hz. By implementing a vacuum chamber system, the pressure variation is reduced from hundreds of Pa/day in atmosphere to a linear variation of ~6 Pa/day. In addition, an active temperature control system can suppress temperature fluctuations by 2 to 3 orders of magnitude within the band from 1×10 -4 Hz to 1×10 -2 Hz. The stability of the proposed MEMS gravimeter is demonstrated via long-term Earth tides observations within a 30-day time span, giving a correlation coefficient of 0.957 with the reference. An excellent bias instability of ≤4 μGal is demonstrated within the 8-3000 s averaging time range, representing one of the best performances to date in terms of stability for MEMS gravimeters. This shows the potential of high-performance MEMS gravimeters for petroleum and mineral prospecting, seismology and other geophysical applications.

The sealing characteristics of the geological formation located above a CO2 storage reservoir, the so-called caprock, are essential to ensure efficient geological carbon storage. In case CO2 were to leak through the caprock, temporal changes in fluid geochemistry can reveal fundamental information on migration mechanisms and induced fuid-rock interactions. Here, we present the results from a unique in-situ injection experiment, where CO2-enriched fluid was continuously injected in a faulted caprock analogue. Results show that the CO2 migration follows complex path- ways within the fault structure. The joint analysis of noble gases, ion concentrations and carbon isotopes allow us to quantify mixing between injected CO2-enriched fluid and resident formation water and to describe the temporal evolution of water-rock interaction processes. The results presented here are a crucial complement to the geophysical monitoring at the fracture scale highlighting a unique migration of CO2 in fault zones.
