As a demonstration, a web application, Water Digital Avatar, was built from these ROMs to quickly and accurately process predictions of water properties and scaling potential on the basis of the entered water composition and desired...

... Abstract Current seawater fluid systems were designed to reduce the usage of fresh water and the number of trips needed to transport the water. The composition of such fluids needed gel stabilizers to reduce the negative effects high salinity waters have on fluid performance. However...

... in the brine was investigated. It was found that the iron sulfide (FeS) scale was always formed on the mild steel surface under various brine compositions due to the fast kinetics of the sulfide scale precipitation and sour corrosion. While with the presence of calcium, the carbonate scale was easier to form...

... cement would lose its mechanical performance and barrier properties when exposed to high temperatures and acidic environments. Thus, modified cements with adapted mineral compositions have been promoted for the specific use in Geothermal wells construction. As based on different mineralogy, these blends...
