The kinetic isotope effects (KIEs), kH/kD, have been determined for reaction of CH3I/CD3I with several organoplatinum(II) complexes [PtR2(NN)], in which the bidentate NN ligand is bpy = 2,2′-bipyridine, tBu2bpy 4,4′-bis(tert-butyl)-2,2′-bipyridine, phen 1,10-phenanthroline, or Me2phen 2,9-dimethyl-1,10-phenanthroline, at different temperatures and solvents having polarities. values obtained secondary α-deuterium KIEs are close to 1 dependent on solvent; up 7−10% larger reactions polar...
Waterflooding is potentially a viable approach to enhance oil recovery, though its efficacy can profoundly be compromised due formation damage as result of inorganic scale deposition. In this study, series high-temperature core flooding experiments were conducted evaluate two green inhibitors (SIs) folic acid and inulin alternative mitigate mineral The co-injection incompatible brines (with without SIs) for flow rates 0.5 3 mL/min into samples dolomite sandstone was experimentally...
Many aspects of oilfield scale inhibition with green inhibi-tors (SIs) have remained untouched. For instance, the discharge large amounts produced water containing various types hazardous chemi-cals, such as SIs into environment has become a major concern. In-stead, environmental regulators encourage operators to look for greener SIs. In this study, performance SI was investigated using PHREEQC simulation. specific case two brines are considered mix incompatibly estimate critical mixing...
Summary The deposition of inorganic matters onto rock surfaces emanates from the interfacial interactions present in scale/brine/rock system. Accordingly, experimental work this study investigates incompatibility cationic and anionic brines with/without dolomite at elevated temperature. For doing so, brine included 6500 ppm ?SO?_4^(2-) is mixed with three different solutions which possess 3000, 6000 9000 ?Ca?^(2+), respectively. observed findings imply that more gypsum deposits are obtained...
Summary Deposition of calcium carbonate and sulfate mineral scales is the major problem encountering to oil industry. Indeed, these salts exist co-precipitate in system seawater injection for purpose EOR. For a long time, scale adhesion has been matter much attention. Instead difficult removal, it seems that inhibition can be suitable alternative, as prevention better than cure! This paper investigates efficiency through two distinct green inhibitors (SI), (A) (B). The experimental results...
The deposition of asphaltene in well columns would compromise flow assurance and possible occurrence under deposit corrosion. formed is the net difference between removal fouling. While there has been a body research on deposition, subjects its dominant mechanisms have received less attention. present study therefore examines most important shear force, rolling, rebound field operating conditions. To achieve this, critical velocity was examined as function oil properties density (870-1000...
