  The process of primary migration, which controls the transfer of hydrocarbons from source to reservoir rocks, necessitates the existence of fluid pathways in low permeability sedimentary formations. Primary migration starts with the maturation of organic matter that produces fluids which increase the effective stress locally. The interactions between local fluid production, microfracturing, stress conditions, and transport remain difficult to apprehend in shale source rocks. Here, we analyze these interactions using a coupled hydro‐mechanical numerical model based on the discrete element method. The model is used to simulate the effects of fluid production emanating from kerogen patches contained within a shale rock alternating kerogen‐poor and kerogen‐rich layers. We identify two microfracturing mechanisms that control fluid migration: i) propagation of hydraulically driven fractures induced by kerogen maturation in kerogen‐rich layers, and ii) compression induced fracturing in kerogen‐poor layers caused by fluid overpressurization of the surrounding kerogen‐rich layers. The relative importance of these two mechanisms is discussed considering different elastic properties contrasts between the shale layers, as well as various stress conditions encountered in sedimentary basins, from normal to reverse faulting regimes. The layering in shales causes local stress redistribution that controls the prevalence of each mechanism over the other and the onset of microfracturing during kerogen maturation. Results are applied to the Draupne formation, a major source rock in the Norwegian continental shelf in the North Sea.

  Depleted oil reservoirs are considered a viable solution to the global challenge of CO2 storage. A key concern is whether the wells can be suitably sealed with cement to hinder the escape of CO2. Under reservoir conditions, CO2 is in its supercritical state, and the high pressures and temperatures involved make real-time microscopic observations of cement degradation experimentally challenging. Here, we present an in situ 3D dynamic X-ray micro computed tomography (μ-CT) study of well cement carbonation at realistic reservoir stress, pore-pressure, and temperature conditions. The high-resolution time-lapse 3D images allow monitoring the progress of reaction fronts in Portland cement, including density changes, sample deformation, and mineral precipitation and dissolution. By switching between flow and nonflow conditions of CO2-saturated water through cement, we were able to delineate regimes dominated by calcium carbonate precipitation and dissolution. For the first time, we demonstrate experimentally the impact of the flow history on CO2 leakage risk for cement plugging. In-situ μ-CT experiments combined with geochemical modeling provide unique insight into the interactions between CO2 and cement, potentially helping in assessing the risks of CO2 storage in geological reservoirs.

  Field observations and geophysical data reveal a causal link between brittle seismic failure and eclogitization of the lower continental crust. We present results from experimental deformation of plagioclase-rich samples at eclogite-facies conditions and quantify the link between rock rheology and the kinetics of the eclogitization reactions. The deformation was ductile both in the absence of reaction and when the progress of eclogitization was fast compared to the imposed strain rate. However, when the reaction rate was relatively slow, the breakdown of plagioclase into nanocrystalline reaction products induced a weakening that triggered seismic failure. Fluid-induced plagioclase breakdown under eclogite- facies conditions is an exothermic reaction accompanied by a negative change in solid volume. This is similar to other mineral transformations that are known to trigger transformational faulting. We demonstrate that mineral reactions lead to brittle deformation in situations where reaction rates are slow compared to the deformation rate. This reaction-induced instability may provide a generic mechanism for embrittlement at depths beyond the normal seismogenic zone.

  Understanding maturation of source rock is increasingly of interest in both conventional and unconventional plays. Shale diagenesis and hydrocarbon generation in shales has a direct relationship with the evolution of the mechanics of maturation. The Draupne Formation, a world class source rock, which stretches over a broad range of depths and maturity, provides the ideal candidate to study the interplay between maturation and geomechanical parameters. Wireline logs and Rock-Eval data from eight wells were used to analyse how seismic waves and rock strength interplays with the source rock shales. Results reveal that the Draupne shale behaves typically in terms of maturation, however the relationship between maturation and geomechanics counters the common trend for shale. There are a wide variety of factors that could impact the geomechanical trends, including but not limited to, lithology, mineralogy, pressure, temperature, fluid content, diagenesis, compaction, fracture density, and organic content. This paper identifies key relationships between geomechanical parameters and a number of these factors, while identifying further work that could be carried out in other areas. This further highlights the importance of in-depth play fairway analysis and presents questions that require answers for successful exploration and exploitation of hydrocarbon

  Understanding shale’s geomechanical and elastic properties is critical to success in conventional and unconventional plays. This understanding provides a framework for the safe extraction of hydrocarbons as well as a guide to mapping favorable source locations. The Upper Jurassic Draupne shale in the North Sea is a world class organicrich source rock, a commendable seal for both hydrocarbon and possibly CO2, and potentially a future reservoir. As such, the Draupne Formation is an ideal candidate to study the modeling of maturation as they relate to both elastic and geomechanical properties.

  Antimony, which has damaging effects on the human body and the ecosystem, can be released into soils, ground-, and surface waters either from ore minerals that weather in near surface environments, or due to anthropogenic releases from waste rich in antimony, a component used in batteries, electronics, ammunitions, plastics, and many other industrial applications. Here, we show that dissolved Sb can interact with calcite, a widespread carbonate mineral, through a coupled dissolution–precipitation mechanism. The process is imaged in situ, at room temperature, at the nanometer scale by using an atomic force microscope equipped with a flow-through cell. Time-resolved imaging allowed following the coupled process of calcite dissolution, nucleation of precipitates at the calcite surface and growth of these precipitates. Sb(V) forms a precipitate, whereas Sb(III) needs to be oxidized to Sb(V) before being incorporated in the new phase. Scanning-electron microscopy and Raman spectroscopy allowed identification of the precipitates as two different calcium–antimony phases (Ca2Sb2O7). This coupled dissolution–precipitation process that occurs in a boundary layer at the calcite surface can sequester Sb as a solid phase on calcite, which has environmental implications as it may reduce the mobility of this hazardous compound in soils and groundwaters.

  Pseudotachylite-networks in granulites on Holsnøy in the Bergen Arcs, SW Norway, and seismic tomography of the Tibetan plateau reveal that earthquakes were triggered even at the high temperature/ high pressure conditions of the lower continental crust. Both, field and geophysical observations, demonstrate a strong link between the nucleation of intermediate-depth earthquakes and areas of partial eclogitization within nominally anhydrous granulitic lower crust. This study presents four deformation experiments performed on granulite samples from Holsnøy. To accelerate reaction kinetics, which is very slow in dry rocks, we applied confining pressures of 2.5-3 GPa and temperatures in the range 995-1225 K, significantly higher than the expected eclogitization conditions of the Bergen Arcs (pressure= 1.5-2 GPa, temperature= 923-973 K). Based on the mechanical data, micro- and nanostructural observations, and recorded acoustic emissions, we were able to correlate the degree of eclogitization to the rheological behavior of the samples. Depending on the net eclogitization rate relative to the deformation rate (5∙10-5 s-1) the sample either behaved strong and ductile if no reaction occurred, mainly brittle when the rate of eclogitization was slow, or mostly weak ductile when the rate of eclogitization was fast. Our experimental results emphasize that shear localization due to grain size reduction triggered by the breakdown of plagioclase under eclogite-facies conditions lead to brittle failure accompanied by acoustic emissions. These and other experiments on a variety of lithologies suggest that there could be one common mechanism that triggers intermediate and deep earthquakes.
