Ingidol AK

Polyamide base

20.59.59-240-14023401-2019

Ingidol AK is a composition of polyamide products on the basis of hydrolytic sapropel. Ingidol AK has 100% solubility in water, it is a molecular solution. The product has been elaborated as an alternative to oil-base muds, first of all, for drilling at the West Siberia fields under temperatures of 90-100C. It is designed to provide high inhibiting and consolidation properties.

The Ingidol AK polyamide base is delivered in steel drum containers or polypropylene barrels of 250 kg.

Purpose

Ingidol AK polyamide base is used to prepare well construction and workover process fluids, to reduce clay hydration. The inhibiting effect is created due to binding of a most part of water.

Advantages

High inhibiting capacity of Ingidol AK based fluids can be achieved without KCl added.

The solution has high anti-dispersion activity, which prevents formation of shale collars, caving and well narrowing.

Ingidol AK based drilling fluid specific density starts from 1.25-1.3 g/cm3 even without solids added. Thus the fluid can be used for well killing. Ingidol AK is a low-hazardous substance by health effect degree.

If it is used in composition with Terra FL fluid loss reducing agent, the minimal filtration rates can be achieved.

Recommendations to application

Working fluid preparing process includes consequent mixing and dissolving raw components. Ingidol AK polyamide base is added to biopolymer solution in concentration of 20% to 80%, depending on the ready fluid properties. To obtain the solution, by its inhibiting properties comparable with oil-based mud, it is recommended to enter Ingidol AK polyamide base in 50-70% concentration. All of the water-soluble components (polymers, salts etc) are to be dissolved in water first, and only then they should be mixed with the drilling mud, because, if they are entered directly into a polyamide solution, they would be very slow to dissolve.
