Curiosity at Gale Crater, Mars: Characterization and Analysis of the Rocknest Sand Shadow

Abstract : A core flow test autoclave has been designed in order to reproduce an injection well at a scale of 1/20. This autoclave allows the CO2 injection into a steel tube cemented to a core sample of red sandstone from the Triassic formations of Lorraine (France). Temperature and pressure gradients can be recorded between the injection point and the confining water phase. Such gradients imply solubility gradients of CO2 and mineral species into the water phase as permeability changes with time. Some chemical reactions can be observed from collected sample at the end of the experiment. Precipitation and dissolution are suspected both into the cement and rock phases. No fracturing is observed. Cement-rock interface is not opened.
