The patented Sorb™ solid inhibitors prevents downhole deposition and tubular damage, resulting in enhanced flow assurance that increases production with less nonproductive time (NPT). Sorb chemicals inhibit scale, paraffin, asphaltenes, and salt; they counteract bacteria and corrosion. In multistage completions, Sorb specialty chemicals prevent problems from a traditional intervention standpoint.
Producing wells often experience flow assurance challenges caused by corrosion and inorganic and organic deposition corrosion, leading to reservoir souring. The patented Sorb solid inhibitors safely and efficiently inhibits downhole deposition or tubular damage with slow-releasing and long-lasting chemicals applied to a solid substrate and pumped deep into the formation.
Sorb solid inhibitors are matched to the specific reservoir, stimulation fluid, and well environment. They are designed to mitigate a wide range of downhole flow assurance risks including scale, paraffin, and asphaltene deposition. The treatment beings before the produced fluids reach the sensitive areas of the formation where temperature or pressure changes commonly cause flow-assurance and corrosion problems.
Conventional treatments, such as continuous squeezing, injection, or batch treating liquid chemicals and pumping liquid inhibitors in stimulations not only delay production but they are expensive and still do not provide a long-term flow assurance solution.
The Sorb chemicals last longer than conventional, liquid flow assurance chemistry because, as a solid, these chemicals slowly desorb into the appropriate fluid. For example, ScaleSorb™ solid inhibitor desorbs in the water phase, whereas ParaSorb™ solid inhibitor and AsphaltSorb™ solid inhibitor desorb into the oil phase. In addition some liquids flow back with the bulk production, regardless of solubility, and may be completely absent from the well by the time it is needed to perform its job. In some cases, Sorb inhibitors have remained in production fluids at effective levels five years after placement.
