The interactions between water-saturated supercritical carbon dioxide, organics, and minerals are relatively unknown despite being important to carbon sequestration and enhanced hydrocarbon recovery activities. The goals of this study include verification of organic transport through scCO2 and exploration of whether organic ligands can impact carbonate formation. An in situ near-infrared spectroscopic...
In the process of reservoir water-flooding development, the injected water of sodium sulfate type and calcium, barium and strontium ion in high salinity formation water combine to form slightly-soluble sulfate scale, result in low efficiency of water injection system and reduction of water-flooding swept volume. In view of above problems, nanofiltration (NF) will be a main driver in injection water...
