... informed decisions based on real-time insights. The proposed DSS is tested using synthetic data modeled on a real field, considering key operational factors such as scale precipitation, energy consumption, and equipment efficiency to identify inefficiencies and potential risks. The alarms...

... on the amount of products that have precipitated upstream the point of interest, good data on kinetics may be more important than high accuracy in solubility calculations. This implies that precipitation rates based on thermodynamic equilibrium will be conservative for the wells and the MEG injection point, i.e...

... on the pipeline's surface was computed using the level set method. The precipitation process of the pipeline was simulated across diverse flow field and response reaction kinetics, culminating in the determination of the reaction rate (K) based on changes in the pipeline's geometric shape. In instances of slow...

... is assessing the scale risks simulation and simple laboratory tests. The results of both methods show very high risks of precipitation likely to disturb process operations. The scale quantity is also very sensitive to pH modification. Then, three different scale mitigations solutions were evaluated to prevent...

Abstract Asphaltenes and waxes can precipitate and deposit in reservoirs, wells and equipment increasing production and operation costs. Previous studies showed the co-precipitation of these heavy organic...

.... The abstract must contain conspicuous acknowledgment of OTC copyright. Abstract Asphaltenes are a major problem for oil industry. Their variability in size, structure and polarity presents a challenge to develop formulations that are effective against precipitation and deposition for all types of asphaltenes...

... classes of polymers have been developed into paraffin inhibitors to delay the onset of paraffin precipitation and alter the crystal morphology of the precipitated paraffin particles – these combined phenomena reduce the extent of deposition. While these polymers control wax deposition, several challenges...

Laboratory testing showed good aqueous solubility of the branched C 12,13 -alcohol-7PO-sulfate in seawater with about 3.5% TDS and 1800 ppm divalent ions (minor calcium and major magnesium ions). The pH buffer selected for this application gave a pH of 7 to 9 to: Prevent precipitation of Ca...
