HimStab Fe

The iron stabilizer “HimStab Fe” restores the trivalent ions of iron (Fe3+ ) to its bivalent ions (Fe2+), as a result of which the iron ions do not effect the formation fluid. The stabilizer prevents formation of insoluble sediments and viscous emulsions, with the trivalent iron present, when the acid enters into reaction with rock. Required concentration of the stabilizer is 0.8 to 1.0% (5000 ppm of iron) and 0.5 to 0.7% (2500 ppm of iron). It is obligatory to carry out compatibility testing before its application.

There are 3 basic brands depending on the application temperature.

• Grade «A», liquid form for formation temperatures up to 90°С;
• Grade «Б» , liquid form for formation temperatures from 60 to 120°С;
• Grade «B», dry form for formation temperatures up to 120°С.

Additionally, if necessary, the application of the “HimStab A” activator should be considered in the presence of high temperatures. The product is delivered in dry form, which is very convenient for use.
