Deposits of barium sulfate are a common issue in the oil and gas industry. The presence these crystals impacts production, causing technical problems such as inhibiting flow rate, increasing pressure pipe, pipe to break be damaged. results this study show formation (BaSO4) with batch crystallizer method at 300 °C under influence stirring rotation speed (0 rpm, 120 240 360 480 rpm) additive conc...

One of the world's largest concentrations of sediment-hosted stratiform zinc-lead-barite deposits is (Figure 1). The largest and most developed of these is located in the Gataga area of northern British Columbia the CirqueiSouth Cirque deposit, with estimated geological reserves of 38.5 million tonnes averaging 8.0% Zn, 2.2% Pb and 47.2 gitonne Ag at Cirque and gitonne Ag at South Cirque (M...

The chemical and isotopic compositions of oceanic biogenic and authigenic minerals contain invaluable information on the evolution of seawater, hence on the history of interaction between tectonics, climate, ocean circulation, and the evolution of life. Important advances and greater understanding of (a) key minor and trace element cycles with various residence times, (b) isotopic sources and s...

Barium sulphate (BaSO4) precipitation has been suggested to occur by non-classical pathways that include the formation of a dense liquid precursor phase, nucleation of primary nanoparticles and two levels of oriented aggregation resulting in micron-sized barite single crystals. In this study we build from this previous knowledge and explore how Ba and SO4 2− ions associate in solution prior to ...

Monitoring and controlling of mineral precipitation is a major challenge in several industry segments such as oil gas or geothermal energy. Especially at elevated pressures, temperatures, salinities, these reactions are poorly understood difficult to predict. Real-time monitoring under conditions, however, crucial for reduction prevention scaling well process modelling. In this study, novel fib...
