INC 1490 Non-Emulsifying Corrosion Inhibitor Intermediate is a high molecular weight imidazoline formulated to reduce emulsification tendencies. It provides excellent film persistency and stability in oilfield brines. It does not require additional emulsion breakers when formulated with polymer acids and surfactants.

Usage Information
  • Formulations based on INC 1490 Non-Emulsifying Corrosion Inhibitor Intermediate may be applied preferentially in batching operations via a chemical injection truck or wellhead lubricators.
  • To establish a good initial film, it is recommended that 2 to 5 gallons of the final blend of INC 1490 be batched into the annular space, and the well put on circulation for 4 to 6 hours.
  • Preferably, sufficient time should be allowed to provide more than one pass around the tubulars prior to putting the well back on production.
  • Recommended dosages for batch-treatment range from 25 to 60 ppm. based on the well’s total production per treatment period, and the severity of corrosion.
  • A good rule of thumb is to batch no less than one gallon per treatment, as lesser amounts may not provide sufficient product to coat the entire downhole tubulars.
  • Formulations based on INC 1490 Corrosion Inhibitor Intermediate may be injected continuously down the annular space through a side stream flush arrangement in wells which have low fluid levels or are pumped off.
  • Dispersibility in the produced waters is of utmost importance, and this type of application may not be optimal in situations where high fluid levels are encountered.
  • However, the dispersibility of the product may be increased by adding one half to one gallon of INC 1801 Surfactant per drum.
