ChemEOR Inc. SI-731

The term Scale refers to water-borne mineral deposits and suspended solids that precipitate from oilfield waters. The accumulation of such mineral scale deposits downhole can reduce oil production or even block the flow into a production well. These mineral deposits in the surface facilities also can block normal flow or disrupt the efficiency of the separation and processing of produced fluids to meet their specified quality requirements.

Scale inhibitors can be applied down hole in a problem production well or in the surface facilities to delay the onset of these undesirable precipitates. If properly selected, the scale inhibitor treatment concentrations of only a few ppm into the target stream may be effective to prevent scale problems.

ChemEOR scale inhibitors have a wide application and are designed to prevent the formation of common calcium and barium scales even under severe conditions, and at a good value.

• Effective for barium/calcium sulfate, calcium carbonate
• Excellent performance against calcium ions
• Applied widely in squeeze treatments, topside production and seawater injection
• Hydrolytically and thermally stable
• High Performance - Outperforms commonly used phosphonates and polyacrylates types scale inhibitors against barium/calcium carbonate, calcium sulfate
• Easy Implementation - Detectable in oilfield brines for a good control of squeeze treatments. Provides excellent adsorption/desorption profiles
• Improved Thermal Stability - Hydrolytically and thermally stable to at least 180 °C (356 °F)
