The Effects of Dissolved Sodium Chloride (NaCl) on Well Injectivity during CO2 Storage into Saline Aquifers
Abstract: Among different options proposed for carbon dioxide (CO2) storage and sequestration, saline formations seem promising due to their wide availability and potentially large storage capability. As supercritical (SC) CO2 is injected into the formation, a variety of coupled processes takes place. Halite precipitation requires particular interest due to its potentially significant impact on permeability impairment, and thus reduction of injectivity in the near well bore region. The selected candidate for …

Mud Acid Effect on Fines Migration Problem Using a Newly Developed Al/Zr-Based Clay Stabilizer (A): Mitigation Can Happen
Abstract: Sandstone reservoirs exhibit severe fines migration problems subsequent to conventional mud acid (HCl: HF) treatments. The acid treatment proved to be effective for a relatively short period of time, with a sudden production decline owing to either that mud acid spent rapidly in close proximity to the wellbore, causing clays to migrate into the acidized area and re-plug the formation; or that the mud acid system actually weakens the structure …

Use of Industrial and Agricultural Waste in Soil Stabilization
Abstract: Soil is the foundation material, which supports loads from the overlying structure. Soil is the most widely used material in a highway system, either in its natural form or in a processed form. Also, all pavement structures eventually rest on soil foundation. The construction cost can be considerably decreased by selecting local materials including local soils for the construction of the lower layers of the pavement such as the sub-base …

Utilization of Flue Gas Conditioned Fly Ashes in Cement and Construction Industries
Abstract: Fly ash is a waste generated from coal based boilers and has been used in various civil engineeringapplications. The pozzolanic activity of the fly ash plays a major role in its utilization. The ageing of theelectrostatic precipitators (ESPs), variation in coal and ash properties results in higher suspendedparticulate matter (SPM) emissions. Globally the SPM limits are being reduced, flue gas conditioning(FGC), i.e. dosing of ammonia and sulphur trioxide to the …

Prediction of Transformer Oil Parameters Using UV/VIS Spectroscopy Graphs
Abstract: AbstractUltraviolet–visible rays (UV/VIS) spectroscopy is a method based on a spectrum, which forms a graph between radiations absorbed by the material and the wavelength of the radiations. UV/VIS spectroscopy is able to tell the impurities or decay contents present in any sample material. In this paper, we have used data collected from various tests performed on the transformer oil samples and compared these results with the UV/VIS spectroscopy results. This …
