Detectability of smart proppants traced with gadolinium and samarium in the Vaca Muerta formation [PDF]
Journal of Petroleum Science and Engineering, 2019 Abstract The use of smart proppants traced with gadolinium and samarium was evaluated in a realistic model by Monte Carlo simulations. The addition of compounds with high thermal neutron capture cross section, such as gadolinium oxide (Gd2O3) and samarium oxide (Sm2O3) into ceramic proppants, makes them detectable after placement in induced ...

Lethaia, 2023 In most oxygen-deficient ancient successions, Chondrites and Zoophycos are typical and recurrent trace fossils that are the last to disappear during deoxygenation events. Here, we report an unusual case of an oxygen-deficient ichnofauna lacking Chondrites and showing scarce Zoophycos, from the Upper Jurassic-Lower Cretaceous Vaca Muerta Formation of ...

Basin Research, Volume 35, Issue 5, Page 1840-1855, October 2023., 2023 Schematic representation of Cerro Alquitrán intrusive body. The drawing shows how magmatic brittle structures and structures in the host rock affect subsurface hydrocarbon migration and seepage. Abstract Cooling subvolcanic igneous intrusions are known to have a substantial impact on fluid flow in the shallow Earth's crust, for example activation of ...

Metal in mesosiderites: Evidence for redox and fractional crystallization
Meteoritics &Planetary Science, Volume 58, Issue 9, Page 1211-1228, September 2023., 2023 Abstract Mesosiderites are an amalgamation of crustal silicates and molten metal, and their formational history is not well understood. It is widely believed that redox reactions occurred in the mesosiderites during metal–silicate mixing. Previous studies evaluated redox reactions by studying the silicates within mesosiderites, but little attention has

Geofluids, Volume 2022, Issue 1, 2022., 2022 Aiming at the problem that casing deformation can easily occur in tight oil horizontal well fracturing, based on the rock mechanics experiments and probability statistics, the distribution characteristics and law of the near‐wellbore stress field of the reservoir in STH M56 were solved and analyzed by using the finite element modeling numerical method.

Journal of Geophysical Research: Solid Earth, Volume 126, Issue 7, July 2021., 2021 Abstract This study investigates the nano to core‐scale geomechanical properties of a maturity series of organic‐rich, calcareous shales buried to 100°C–180°C, with a focus on: (a) the mechanical properties of organic matter; (b) the elastic response and anisotropy of the shale composite at micro and core scale; and (c) the creep response.
