- Formulations based on INC 2277 do not offer the thermal stability of either the phosphonates or the acrylates, having a maximum temperature tolerance of approximately 170 ºF; thereafter exhibiting thermal degradation. However, INC 2277 is a better overall inhibitor in that it can successfully inhibit the formation and deposition of the three major oilfield scales - Calcium Carbonate, Calcium Sulfate, and Barium Sulfate - at lower ppm than either the phosphonates or the acrylates.
- Unneutralized formulations of INC 2277 have been successfully used in squeeze applications, both in single-component blends, or in combination with INC 2241, or INC 2213. In the presence of limestone, INC 2277 will precipitate a slightly soluble calcium salt, which will slowly feed back into the wellbore, protecting against the formation and subsequent deposition of mineral scales in the downhole surfaces. A typical formulation of INC 2277 may consist of between 9 to 13 gallons of INC 2277 in water. The formulation may be neutralized with caustic soda, caustic potash, or aqua ammonia, the pH dependent on the solubility characteristics desired. It has been our experience that at lower pH values (3 to 5), finished formulations will exhibit a better tolerance to high-calcium content in produced waters, especially when neutralized with aqua ammonia.
- INC 2277 Scale Inhibitor Intermediate may also be formulated into combination scale & corrosion inhibitor finished products. Typically these formulations may consist of 3 to 9 gallons of scale inhibitor, along with 9 to 3 gallons of a water soluble corrosion inhibitor such as INC 2421 or INC 1477, with the idea of tayloring a product to the situation at hand. Most often 6 gallons of scale inhibitor and 6 gallons of corrosion inhibitor in water make up the typical blend.
- We recommend that finished formulations of any scale inhibitor be tested to determine its solubility in any given water to be treated.
