Regular well pattern provided longer oil production time at a constant rate until CO 2 breakthrough compared...

... Abstract When conducting enhanced oil recovery (EOR) projects, utilizing CO 2 as a solvent, there are three primary options for sourcing the CO 2 injectant. These are naturally occurring deposits, anthropogenic flue gas capture, or recycled CO 2 from an earlier stage of an EOR project. All...

... of the saturated water content of acid gas mixtures up to 69000 kPa. With gases containing CO 2 , the CO 2 must be converted to an "equivalent" H 2 S concentration. For purposes of this predictive tool, it is assumed that the CO 2 will contribute 75% as much water to the gas mixture, on a molar basis, as H 2 S...

...Phase research of H₂S and CO₂ Equation of state (EOS) is effective in phase research. The properties of H 2 S and CO 2 and their mixture in six phases area are calculated by SRK(Soave-Redlich-Kwong) equation, PR(Peng-Robinson)equation, PT equation and PR-Mathias equation...

Lab experiment shows that the high efficient dissolver agent may decrease the viscosity of the heavy oil around...

... reservoir, the Saskatchewan Research Council (SRC) conducted a laboratory feasibility study of augmenting the injection water with chemicals (alkaline/surfactant/polymer). The resulting process is known as CAG, or chemical-alternating-gas (CO 2 or flue gas). SRC's integrated approach included interfacial...

... Abstract The effect of completion techniques and reservoir heterogeneity on CO 2 storage and injectivity in saline aquifers has been studied using a compositional reservoir simulator CMG-GEM. Two reservoir models were built using data extracted from publications, to represent a deep saline...

... encountered in this kind of reservoir. Experiments were conducted in vug-pore artificial cores with the size of 4.5 × 4.5 × 30 cm to study the influence of viscosity and different inclination angle on the oil recovery (OR). The influence of N 2 and CO 2 on the relative location of the water-oil/gas-water...

... in the presence of aggressive formation and injection fluids (such as magnesia or sulfate containing brines and CO 2 ) are given. API cement hydration mainly produces Calcium-Silicate-Hydrate (C-S-H) phases, which are responsible for the strength, and portlandite "Ca(OH) 2 " which is basically a weak point within...

... Abstract Supercritical pipelines are most commonly used in CO 2 transportation. Liquid models are always utilized for design and hydraulic checking of those pipelines. However, supercritical CO 2 may show significant characteristics of gaseous under certain operating condition...

With the increasing CO 2 concentration in the natural gas, the calculation error of vdW-P model increased, but the Chen-Guo model's reduced. In general, the Chen-Guo model is superior to the vdW-P model. Based on the experimental data...
