Experiments were conducted to assess the potential impact of fractured well-cement degradation on leakage rate. Permeability was monitored while CO2-enriched reservoir-equilibrated brine flowed at constant rate through a single fracture in class G cement core under conditions mimicking geologic sequestration environments (temperature 60 °C, pressure 10 MPa). The results demonstrate that, least for used experiment, an initial 42 μm aperture (permeability = 1.5 × 10(-10) m(2)) can be...
The potential for mineral carbonation of carbon dioxide (CO2) in a plutonic mafic rock is addressed this work through set laboratory experiments on gabbro-anorthosite sample from the Torrão - Odivelas Massif (Portugal). experiment was conducted two stages under pressure (8 MPa) and temperature (313.15 K) conditions similar to those expected around CO2 injection well. Stage-I simulated dissolution conditions, with crushed (1–3 mm) exposed 30 days supersaturated seawater (0.576 M). Stage-II...
The potential for mineral carbonation of CO2 in plutonic mafic rocks is addressed through a set laboratory experiments on cumulate gabbro and gabbro-diorite specimens from the Sines Massif (Portugal). were conducted an autoclave, maximum 64 days, using supersaturated brine under pressure temperature conditions similar to those expected around injection well during early-phase injection. Multiple techniques mineralogical geochemical characterization applied ante- post-carbonation experiments....
Adequate hydrogeophysical monitoring of CO2 geological storage remains a challenge as different parameters might be modified during storage. That implies to compare real-time measurements an adequate baseline. At the Maguelone shallow experimental site representative baseline for electrical resistivity was built from large number downhole geophysical measurements. this coastal issue is particularly important due production biogenic gas subsurface sediments. For this, petrophysical model...
<p>The focus of this research is a qualitative study mineralogical and chemical changes in plutonic mafic rock samples after exposure to CO<sub>2</sub>-rich brine, under supercritical conditions (SC), clarify the behavior brine initial stages mineral carbonation. The studied consists gabbro-anorthosite from Odivelas massif, southern Portugal. sample was exposed SC (P≈8 MPa,...
