“…Also, the bands were detected at 2513 and 2916/cm, which indicated the calcite and C-C (mode of vibration). The bond at 1795 was assigned to the calcite vibration mode [21,[23][24][25][26]. Figure 3 shows the morphology of calcium carbonate nanoparticles.…”

Application of nanoparticles in improvement of drilling fluid properties through effective control of fluid loss and rapid formation of thin, smooth and low permeable filter cake has gained considerable attention in recent years. In this study, calcium carbonate nanoparticle was synthesized by precipitation method and characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscope (SEM), dynamic light scattering and Zeta-potential measurement. Water based bentonite drilling fluid was used as base fluid. Various concentrations of calcium carbonate nanoparticle (0.025-0.5 wt%) was added to water-based drilling fluid. Fluid loss volume, filter cake thickness and its surface morphology, and rheological properties of both base fluid and fluid containing calcium carbonate nanoparticles was measured and compared. Results show that addition of calcium carbonate nanoparticle greatly affects filtration properties and forms smoother cake surface. Optimum concentration of 0.07 wt% calcium carbonate nanoparticle was obtained which results in reduction of fluid loss volume and filter cake thickness by 26% and 64% respectively while minor change in rheological behavior was observed. SEM image showed smoother cake surface of drilling fluid with calcium carbonate nanoparticle as additive compared to base drilling fluid. Considerable improvement in filtration properties using acid soluble CaCO 3 nanoparticles can help in minimizing fluid leak-off and formation damage of producing layers and more effective well cleanup for fast oil and gas production.

“…A series of scale inhibitors have been developed [16][17][18]. PBTCA (2-phosphonobutane-1,2,4-tricarboxylic acid) is currently widely used as a scale and corrosion inhibitor because of its low phosphorus content and good scale-and corrosion-inhibition performance [19][20][21]. However, there are few reports on the formation and control of scaling substances on the surface of cathodes in equipment such as electrocatalytic oxidation.…”

The formation of CaCO3 crystals on the cathode surface and the scale-inhibition performance of scale inhibitor 2-phosphonobutane-1,2,4-tricarboxylic acid (PBTCA) on the cathode surface were studied by methods of solution analysis, gravimetric analysis, SEM, FTIR, and XRD techniques. They were then compared with the results of the formation and suppression of CaCO3 crystals in aqueous solution. PBTCA had a good solution-scale-inhibition performance and good lattice-distortion effects on CaCO3 crystals in solution, which could change the CaCO3 from calcite to vaterite and aragonite crystals. The solution-scale-inhibition efficiency exceeded 97% when the PBTCA concentration reached 8 mg/L. Under cathodic polarization conditions, the surface-scale-inhibition efficiency of the cathode and solution-scale-inhibition efficiency near the cathode surface both exceed 97% at polarization potential of −1V. The addition of PBTCA significantly reduced the amount of CaCO3 crystals formed on the cathode surface and had good surface and solution-scale-inhibition effect. However, the lattice-distortion effect of PBTCA on CaCO3 crystals disappeared on the cathode surface, and the resulting CaCO3 contained only calcite crystals. The high-scale-inhibition effect of PBTCA under cathodic polarization was mainly due to the inhibition of the formation of calcium carbonate crystals by PBTCA, and not because of the lattice distortion of CaCO3 crystals.

“…Wang et al studied the performance and inhibition mechanism of CaCO 3 scale control in the presence of aluminum oxide (Al 2 O 3 ) nanofluids and commercial SIs such as 2-phosphonobutane-1,2,4-tricarboxylic acid (PBTCA). , Nanoalumina (γ-phase, with 20 nm average particle size) was used in this study. SEM was used to identify the morphology and structure analysis of CaCO 3 crystals in the absence and presence of Al 2 O 3 NPs- co -PBTCA SI.…”

Nanotechnology has grown rapidly in both research and applications over the past two decades including in the upstream petroleum industry. A recent hot area for studying nanotechnology has been oilfield scale management. The formation of oilfield scale deposits such as calcium carbonate and Group II sulfate scales in conduits and on equipment, both downhole and topside, can cause serious loss of hydrocarbon production and unwanted downtime. Scale management is expensive to the field operator, mostly due to downtime causing deferred or loss of production. Many types of nano-based materials and treatments have been developed to combat this problem, most of them containing one form or another of an organic scale inhibitor. In this review, we reviewed the various types of nanotechnologies that have been developed and include comparisons to conventional treatments where available. The nanotechnologies include nanoemulsions, nanoparticles, magnetic nanoparticles, polymer nanocomposites, carbon-based nanotubes, and other miscellaneous technologies. Several nanoproducts developed for squeeze treatments indicate improved squeeze lifetime compared to conventional squeeze treatments. Other potential benefits include improved thermal stability for high-temperature wells, reduced formation damage for water-sensitive wells, and environmental impact.
