“…The reduction in permeability was significantly lower in the trial where salinity changes occurred slowly than when radically decreased in one single step. Similar results were reached when salinity was decreased continuously through the use of a permanent dilution vessel and subjected to constant stirring (Mungan, 1965). In all above works, it was considered that there would be no release of clay particles when salt concentration was slowly decreased (Jones and Frank, 1964;Mungan, 1965).…”

“…Therefore, if the difference in salt concentration is small, the osmotic pressure generated would also be too small to be able to release particles. However, Mungan (Mungan, 1965) showed experimental evidences that, in all previously studied situations, the osmotic pressure would not be enough to release particles. Gray and Rex (Gray and REX, 1966a) proposed that particle releases would be caused by the expansion of clay double layer.…”

“…So far, the studies published have sought explanations for phenomenon related to permeability loss due to the particles migration in sandstones free of expansive clays (Gray and REX, 1966a;Mungan and Moore, 1968). However, the oil reservoirs have both non-expansive and expansive clays (Rosenbrand et al, 2013;Mohan et al, 1993a).…”

“…6c) as infiltration dynamics is captured nicely without the need to incorporate a clogging parameter in the numerical model. It is worth noting that infiltration of low-salinity water into natural settings may cause clogging due to clay swelling, dispersion and colloidal release and deposition, which can lead to K s reduction of up to 2 orders of magnitude (Blume et al, 2002;Lado and Ben-Hur, 2010;Mohan et al, 1993;Shainberg and Letey, 1984). The practical importance of these clogging mechanisms during MAR with DSW is unclear.…”

Abstract. We study the relation between surface infiltration and groundwater recharge during managed aquifer recharge (MAR) with desalinated seawater in an infiltration pond, at the Menashe site that overlies the northern part of the Israeli Coastal Aquifer. We monitor infiltration dynamics at multiple scales (up to the scale of the entire pond) by measuring the ponding depth, sediment water content and groundwater levels, using pressure sensors, single-ring infiltrometers, soil sensors, and observation wells. During a month (January 2015) of continuous intensive MAR (2.45 × 10 6 m 3 discharged to a 10.7 ha area), groundwater level has risen by 17 m attaining full connection with the pond, while average infiltration rates declined by almost 2 orders of magnitude (from ∼ 11 to ∼ 0.4 m d −1 ). This reduction can be explained solely by the lithology of the unsaturated zone that includes relatively low-permeability sediments. Clogging processes at the pond-surface -abundant in many MAR operations -are negated by the high-quality desalinated seawater (turbidity ∼ 0.2 NTU, total dissolved solids ∼ 120 mg L −1 ) or negligible compared to the low-permeability layers. Recharge during infiltration was estimated reasonably well by simple analytical models, whereas a numerical model was used for estimating groundwater recharge after the end of infiltration. It was found that a calibrated numerical model with a onedimensional representative sediment profile is able to capture MAR dynamics, including temporal reduction of infiltration rates, drainage and groundwater recharge. Measured infiltration rates of an independent MAR event (January 2016) fitted well to those calculated by the calibrated numerical model, showing the model validity. The successful quantification methodologies of the temporal groundwater recharge are useful for MAR practitioners and can serve as an input for groundwater flow models.

Frictional stability‐permeability relationships for fractures in shales

et al. 2017

There is wide concern that fluid injection in the subsurface, such as for the stimulation of shale reservoirs or for geological CO2 sequestration (GCS), has the potential to induce seismicity that may change reservoir permeability due to fault slip. However, the impact of induced seismicity on fracture permeability evolution remains unclear due to the spectrum of modes of fault reactivation (e.g., stable versus unstable). As seismicity is controlled by the frictional response of fractures, we explore friction‐stability‐permeability relationships through the concurrent measurement of frictional and hydraulic properties of artificial fractures in Green River shale (GRS) and Opalinus shale (OPS). We observe that carbonate‐rich GRS shows higher frictional strength but weak neutral frictional stability. The GRS fracture permeability declines during shearing while an increased sliding velocity reduces the rate of permeability decline. By comparison, the phyllosilicate‐rich OPS has lower friction and strong stability while the fracture permeability is reduced due to the swelling behavior that dominates over the shearing induced permeability reduction. Hence, we conclude that the friction‐stability‐permeability relationship of a fracture is largely controlled by mineral composition and that shale mineral compositions with strong frictional stability may be particularly subject to permanent permeability reduction during fluid infiltration.
