Remote sensing of vegetation stress has been posed as a possible large area monitoring tool for surface CO2 leakage from geologic carbon sequestration (GCS) sites since vegetation is adversely affected by elevated CO2 levels in soil. However, the extent to which remote sensing could be used for CO2 leak detection depends on the spectral separability of the plant stress signal caused by various ...

Investigating multi cyclic gas (N2 and CO2) huff and puff have been conducted by long sandpack simulations with four different crude oils from Jiangsu oilfield. According to the production differential pressure and the production regularity during huff and puff, the production process was divided into three sections; the first one is free gas production section; the second section is low viscou...

Sequestration of carbon dioxide (CO2) in depleted oil reservoirs is one of the viable options for carbon management. This paper describes the preliminary modeling and flow simulation part of a DOE sponsored CO2 sequestration project. The main objective of the project is to understand the feasibility of long term sequestration of CO2 in a depleted oil reservoir through a field demonstration expe...

She was treated with a process called carboxytherapy that resulted in great improvement of the scars with minimal to no discomfort or down time. Carbon Dioxide (CO2) therapy was first introduced in France for cutaneous use.1 CO2 is a non-toxic gas that is naturally produced by cells as they undergo the process of metabolism. As CO2 accumulates in the tissues it induces dilatation of capillaries...

We propose a carbon storage strategy where CO2 and brine are injected into an aquifer together followed by brine injection alone. This renders 80–95% of the CO2 immobile in porescale (10 s mm) droplets in the porous rock. Over thousands to billions of years the CO2 may dissolve or precipitate as carbonate, but it will not migrate upwards and so is effectively sequestered. The CO2 is trapped dur...

The recovery of natural gas from CH4-hydrate deposits in sub-marine and sub-permafrost environments through injection of CO2 is considered a suitable strategy towards emission-neutral energy production. This study shows that the injection of hot, supercritical CO2 is particularly promising. The addition of heat triggers the dissociation of CH4-hydrate while the CO2, once thermally equilibrated,...

OBJECTIVE We prospectively compared patients' tolerance for and the usefulness of carbon dioxide (CO2) with iodinated contrast material in the study of lower limb arteries in 30 patients. SUBJECTS AND METHODS We systematically performed digital subtraction angiography with electronic injection of CO2 (injection average, 330 ml) and digital subtraction angiography with iodinated contrast mater...
